It was deemed that 232 subjects per age group would be needed. The width of the defined age groups was designed to be equal to 10 years for each of the three groups (18–27, 28–37 and 38–47 years of age) in order to facilitate future determination of incidence in a second cross-sectional survey [16]. In addition, HIV screening data from the routine ANC of the MDH were prospectively collected, stratified by the Fulvestrant mouse predefined age groups and compared with the respective population-based estimates of the same year. At the time the study was conducted,

local guidelines for prevention of mother-to-child transmission of HIV were based on ARV monotherapy administration to the mother from 28 weeks of gestation, plus combined ARVs during labour, and administration of ARVs to the infant for up to

4 weeks. HIV counselling, testing and treatment are available and provided free of charge at the health services in Manhiça Hospital. For the cross-sectional study, Microsoft® Visual FoxPro 5.0 software (Microsoft Corporation, Redmond, WA) was used to generate random lists from the DSS of adults living in the study area stratified Selleck IDH inhibitor by age group and sex, and organized by neighbourhood. The study inclusion criteria were: age 18–47 years, being resident in the main study area, and being willing to participate in the study after signing an informed consent form. Study candidates were recruited regardless of their previously known HIV status. Prior to the study initiation, community sensitization activities were carried out, consisting of informative meetings

about the study and its objectives with the neighbourhood leaders. The selected individuals were visited at home by a study field worker who explained briefly the objectives of the study. If the candidate agreed, he/she was given an appointment card and another home visit was made by a mobile team to provide more information about the study. Voluntary HIV counselling and testing were offered in the households [17]. If the subject was absent, he/she was revisited one more time. In the case of repeated absence or migration, the next listed candidate was visited. At the scheduled date Amobarbital and time, a trained HIV counsellor visited the household. In order to ensure privacy and confidentiality, the counsellor identified an adequate area to perform HIV testing and informed consent. Again, in the case of absence at the time of the visit, candidates were visited only one more time to offer participation in the study. Recruitment was stopped once the minimum sample size for each age and sex group was reached. Basic sociodemographic information was recorded on the study case report form (CRF). Rapid HIV testing was performed by fingerprick following national recommendations using two rapid tests: the Determine HIV 1/2 test (Abbott Laboratories, North Chicago, IL; sensitivity 100%; specificity 99.

This review demonstrates international travelers are at risk of H

This review demonstrates international travelers are at risk of HBV and HCV infection and provides evidence-based information enabling health practitioners to provide more appropriate pre-travel advice. HBV vaccination should be considered in all travelers to countries with a moderate to high HBV prevalence (HBsAg ≥ 2%) and the risk and benefits discussed with the individuals in consultation with the health practitioner. There is no duration of travel

without risk of HBV infection. However, it is apparent that those travelers with a longer duration of travel are at greatest risk of HBV infection (ie, expatriates). selleckchem Travelers should also receive advice regarding the modes of transmission and the activities that place them at risk of both HBV and HCV infection. Over the last three decades, the number of international travelers has risen dramatically. In 2011, the number of international tourist arrivals was 983 million worldwide up from 799 million arrivals in 2005 and 435 million arrivals in 1990.[1] Worldwide, an estimated 350 to 400 million people are living with chronic

hepatitis B virus (HBV) infection and 170 million with chronic hepatitis C virus (HCV) infection,[2] placing a large number of travelers at risk of both HBV and HCV infection. While the incidence of HBV infection in long-term E7080 in vitro travelers (expatriates) has been reasonably well described, there is minimal information mafosfamide available to guide health practitioners on the risks of HBV infection

among short-term travelers or of travel-associated HCV infection. This review focuses on the epidemiology of HBV and HCV in international travelers, the modes of transmission, and the prevention strategies. Evidence-based information is crucial to facilitate informed decision making and support health practitioners in providing more appropriate pre-travel advice. HBV is part of the Hepadnaviridae family in the genus Orthohepadnavirus. It is the leading cause of chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC) worldwide resulting in 500,000 to 1.2 million deaths per year.[2, 3] The prevalence of HBV infection varies widely, so the risk of HBV infection to travelers will alter depending on destination. There are areas of low prevalence (0.1%–2%) including Australia, the United States, Canada, and Western Europe; areas of intermediate prevalence (2%–7% HBsAg+ve) in parts of central Asia, Central and South America, and Eastern Europe; and areas of high prevalence (≥8% HBsAg+ve) in China, Africa, and countries within the Middle East and Southeast Asia (Figure 1).[4, 5] It is estimated that 88% of the world’s population live in intermediate- to high-prevalence countries and >2 billion people have been infected worldwide.[6] The global prevalence of HBV infection and the risk to travelers are likely to decrease as universal vaccination of infants is progressively introduced[7, 8] (Table 1).

6 CFU mL−1) was cultured for 24 h with FC beads at various volume

6 CFU mL−1) was cultured for 24 h with FC beads at various volumes (FC concentration: 30–90 μM) in a simple-PPLO broth (15 mL) containing progesterone

(30 μM), the FC did not inhibit the anti-H. pylori action of progesterone: the CFU increase was not observed in any concentrations of FC (Fig. 4c). The 60 and 90 μM concentrations of FC seemed to decrease the CFU of H. pylori cultured with progesterone (30 μM), but the magnitude of CFU decreases was negligible. These results, at least, indicate that FC does not competitively inhibit the anti-H. pylori action of progesterone. This compelled us, in turn, to examine the inhibitory effect of a high concentration of FC on the anti-H. pylori action Compound Library of progesterone. When the H. pylori (106.3 CFU mL−1) was cultured for 24 h with progesterone at concentrations ranging from 10 to 30 μM in a simple-PPLO broth (15 mL) containing FC beads (FC concentration: 500 μM) or FC-free beads (approximately the same volume), FC at the highest concentration (500 μM) had a noticeable influence on the anti-H. pylori action of the progesterone: the growth-inhibitory

curve of H. pylori cultured with progesterone selleck chemicals in the presence of FC-beads shifted from the control growth-inhibitory curve of H. pylori cultured with progesterone in the presence of FC-free beads to the right side (Fig. 4d). These results indicate that FC noncompetitively inhibits the anti-H. pylori action of progesterone. And taken in combination with the results shown in Fig. 4a and b, they also strongly suggest that progesterone nonreversibly binds to the H. pylori cells and thereby induces the cell lysis and/or inhibits the FC absorption of H. pylori. Earlier investigations (including our own) have shown that H. pylori morphologically converts from a bacillary form to a coccoid form when the organism is exposed to various stresses such as excessive oxygen, alkaline pH, or long-term culture (Catrenich & Makin, 1991; Benaïssa et al., 1996; Donelli et al., 1998; Shimomura

et al., 2004). Cells that change to a coccoid form lack the ability to form colonies on an agar plate, which makes it very difficult to accurately determine the CFU in coccoid-converted H. pylori. The present study revealed that estradiol Inositol oxygenase has the potential to inhibit the growth of H. pylori. We also confirmed that coccoid cells are microscopically unobserved in H. pylori cultured with estradiol (data not shown). Taken together, these results show that estradiol acts bacteriostatically on H. pylori without inducing the coccoid cell conversion. Another recent study demonstrated that estradiol somehow protects against the development of H. pylori-induced gastric cancer in a mouse model (Ohtani et al., 2007). The bacteriostatic action of estradiol may play some role in mechanisms preventing the development of H. pylori-induced gastric cancer. Further investigations will be necessary to elucidate the relationship between estradiol and H. pylori.

However, the lack of temporal specificity inherent in the above t

However, the lack of temporal specificity inherent in the above techniques, such as permanent lesions or long-term blockade, may obscure the more subtle effects that these regions contribute to this task. To address this, we recorded from single neurons in the NAc core U0126 order and shell during the performance of PIT. Further, we assessed how neural encoding was altered by cocaine, a drug that acts by blocking

DA reuptake in the synapse of NAc neurons, by comparing neural firing in animals with a history of cocaine self-administration with naive and saline-infused controls. Experimentally naive male Sprague-Dawley rats (n = 10; Charles River Laboratories), aged between 8 and 12 weeks and weighing approximately 300 g at the time of arrival were used. The individually-housed rats were allowed to habituate to the vivarium for approximately 1 week, during which time they had ad-libitum access to food and water and were maintained on a 12 h light/dark schedule. Following habituation, rats were implanted with indwelling electrophysiological arrays in the core and shell of the NAc (see below). After 2 weeks recovery, rats were shifted to food restriction (unlimited water access) that maintained their weight at 85% of their free-feeding baseline weight. Rats remained on this restricted diet for the duration of the training and test procedures. Animal procedures were conducted in accordance

with

the National Institutes of Health Guidelines for the Care and Use of Laboratory Animals and the guidelines of the University of North Carolina at Chapel Hill Institutional Care STAT inhibitor and Use Committee. Prior to all behavioral testing, rats were anesthetized with medroxyprogesterone ketamine (100 mg/kg) and xylazine (20 mg/kg), and then placed in a stereotaxic apparatus (Kopf Instruments, Tijunga, CA, USA). The scalp was incised and retracted, and the head was adjusted to level in all planes. Holes were drilled in the skull above the NAc core (AP: +1.8 mm, ML: ± 1.4 mm, relative to Bregma) in one hemisphere, and the NAc shell (AP: + 1.8 mm, ML: ± 0.8 mm) in the other hemisphere. The side of the NAc core and shell array placements was counterbalanced across subjects such that approximately equal numbers of recordings were taken from the left and right core and shell subregions, respectively. An eight-wire recording array (NB Labs, Denison, TX, USA) was slowly lowered into the NAc core or shell at a depth of −6.2 mm from the brain surface. The arrays consisted of two parallel rows of four stainless-steel Teflon-coated, 50 μm-diameter wires, tips spaced evenly 0.5 mm apart. A ground wire for each array was placed in the brain distal to the recording location in the same hemisphere. The apparatus was chronically secured with dental acrylic attached to screws placed on the skull surface. Animals were given an oral dose of 1.

Chikungunya virus (CHIKV), is a vector-borne virus transmitted to

Chikungunya virus (CHIKV), is a vector-borne virus transmitted to humans by Aedes spp. mosquitoes. Various outbreaks have occurred in Africa, Southeast Asia, and India since it was first isolated in Tanzania in 1953.[1, 2] In the 21st century after an outbreak described in Kenya, other outbreaks occurred on the Comoros Islands, Réunion, and other Indian Ocean Islands; the epidemic then spread

to India.[3, 4] During summer 2007, for the first time in a temperate climate country, a large outbreak, involving more than 200 cases occurred in Emilia-Romagna region, Italy.[5-7] It has, thus, proven that vector-borne diseases can spread Ku-0059436 cost not only in tropical Vincristine areas but also in all those sites where the vector (in this case the Asian tiger mosquito—Aedes albopictus) is present. Aedes spp. mosquitoes are also considered the competent

vector of Dengue virus (DENV). The geographical distribution of DENV is around the equator where the disease is endemic in more than 110 countries.[8] Its incidence increased 30-fold between 1960 and 2010.[9] In temperate countries, where the competent vector is present, the risk of introduction and transmission of CHIKV and DENV is particularly high. Thus, epidemiological surveillance is crucial to rapidly identify imported cases in order to introduce measures to reduce mosquito density in the area. We report results of DENV and CHIKV surveillance in Italy. Moreover, considering the worldwide spread of DENV and CHIKV and the consequent importation of cases in Italy we estimate the number fantofarone of imported cases using data on airport

arrivals of travelers to the Italian international airports. We describe cases of CHIKV and DENV reported to the National Institute of Health (ISS) and the Ministry of Health, from January 2008 through October 2011. In Italy, the notification of CHIKV and DENV cases is not mandatory, but after the CHIKV outbreak in 2007, some regions (10 of 21 regions) defined a common plan for epidemiological surveillance of CHIKV and DENV fevers. The common plan was implemented based on the presence of the competent vector on regional territory. In 2011, a new national plan on integrated human surveillance of imported and autochthonous vector-borne disease (CHIKV, DENV, and West Nile disease) was issued.[10, 11] The CHIKV and DENV cases were defined according to the EU case definition.[12] Briefly, a confirmed case of CHIKV was defined as a patient with clinical symptoms (sudden onset of fever >38.

The shape of NBD94444–547 in solution was calculated from small-a

The shape of NBD94444–547 in solution was calculated from small-angle X-ray scattering data, revealing an elongated molecule that comprises of two globular domains, this website linked by a spiral segment (Grüber et al., 2010). In many cases, a protein fragment or peptide obtained by cleavage of the full-length protein or by expression of part of the protein can retain a functional domain. This is particularly relevant in drug designing as well as in the search for an antimalarial vaccine, where immunogenic and protective peptides are of prime importance. In this work, we investigated the peptide NBD94483–502, including the amino acids 483FNEIKEKLKHYNFDDFVKEE502,

identified as the nucleotide-binding region of NBD94 protein in Py235 and determined its structure by nuclear magnetic resonance (NMR) spectroscopy. In addition, we also revealed that the erythrocyte-binding property of the reticulocyte-binding protein Py235 was significantly

altered in the presence of this peptide, demonstrating its potential use as a novel drug target. The peptide NBD94483–502 from P. yoelii was synthesized by Liberty Automatic Microwave Peptide Synthesizer (CEM) using N-(9-fluorenyl)methoxycarbonyl chemistry on a Rink amide MBHA resin (Novabiochem, Germany). The C-terminal amidated peptide was purified by reverse-phase HPLC on a Dynamax C-18 column (Varian Inc.), eluted with a linear 5–100% gradient of acetonitrile in 0.04% aqueous trifluoroacetic acid. The identity of the purified peptide was confirmed by MALDI-TOF MS (4800 MALDI TOF/TOF, Applied Etoposide cost Biosystems/MDS Sciex). The purity

of the peptide was confirmed by electrospray ionization-MS. Steady-state CD spectra of NBD94483–502 were measured in the far-UV light (190–260 nm) using a Chirascan spectrometer (Applied Photophysics). Spectra were collected in a 60 μL quartz cell (Hellma) at 20 °C at a step resolution mTOR inhibitor of 1 nm. The readings were an average of 2 s at each wavelength and the recorded millidegree values were the average of three determinations for the sample. The CD spectrum was acquired in a buffer of 25 mM phosphate, pH 6.5, and 30% trifluoroethanol (TFE) with a peptide concentration of 2.0 mg mL−1. The spectrum for the buffer was subtracted from the spectrum of NBD94483–502. CD values were converted to mean residue molar ellipticity (θ) in units of deg cm2 dmol−1 per aa using the software chirascan version 1.2 (Applied Photophysics). This baseline-corrected spectrum was used as an input for computer methods to obtain predictions of the secondary structure. In order to analyze the CD spectrum, the following algorithms were used: Varselec (Manavalan & Johnson, 1987), Selcons (Sreerama & Woody, 1993), Contin (Provencher, 1982) and K2D (Andrade et al., 1993), all methods as incorporated into the program dicroprot (Deleage & Geourjon, 1993). Two millimolar of peptide NBD94483–502 was dissolved in 25 mM phosphate buffer at pH 6.5, 30% TFE and 10% D2O.

Twelve isolates (8%) belonged to group B1, four (3%) to group B2,

Twelve isolates (8%) belonged to group B1, four (3%) to group B2, and eight (5%) to group D (data not shown). The prevalence of VGs among ETEC isolates is higher than non-ETEC Selleckchem Belnacasan isolates (Table 2). Most ETEC isolates that carried the F4 gene were also positive for STa, EAST1, Stx2e, and AIDA-I. Although no VGs could be detected in 10 isolates,

at least two VGs were found in most strains (76%). The average number of VGs (average VG score) was 2.9 (data not shown). Combinations of adhesin and toxin genes encoded by porcine E. coli isolates are presented in Table 3. Most E. coli isolates possessing genes for adhesion also carried toxin genes. Considering all VGs together, a total of 13 different combinations of adhesion and toxin genes were observed. Ixazomib clinical trial Of these 13 combinations,

the most common gene profiles were eae/Stx2e (53 isolates), eae/EAST1 (52 isolates), F4/eae/EAST1 (24 isolates), F4/STa/Stx2e/EAST1 (21 isolates), eae/STa/Stx2e/EAST1 (20 isolates), and F4/STa/EAST1 (18 isolates). All F18-positive isolates possessed genes for EAST1, Stx2e, and AIDA-I. Of 22 EAST1/STa/Stx2e-positive isolates, 15 carried the F4 gene. EAST1 was found to be significantly associated with F4 (P=0.002), STa (P=0.002), STb (P=0.003), and AIDA-I (P=0.01) (data not shown). The distribution of VGs in relation to four phylogenetic groups showed that the presence of VGs differed minimally among the four phylogenetic groups, with a P-value >0.05 (data not shown). Among 167 isolates, 152 different PFGE profiles were obtained according to the criteria of Tenover et al. (1995), suggesting that most of the isolates in the study were not from

a specific E. coli clone. The possible statistical association between antibiotic resistance/susceptibility phenotypes, VGs, and the phylogenetic background of epidemiologically unrelated isolates was subsequently investigated. However, we found that the distribution of phylogenetic groups in relation to AMR phenotypes however was not different (P>0.05), with the exception that streptomycin-resistant isolates significantly belonged to group A (P<0.05) (data not shown). However, a more detailed analysis revealed two further groups of associations: first, an association between resistance to ceftiofur and the presence of F4 (95% CI, 8.36–102.4, P<0.0001) and AIDA-I (95% CI, 1.16–13.03, P=0.044), and second, an association between resistance to doxycycline and the absence of Stx2e (95% CI, 0.20 to −0.93, P=0.03), as well as resistance to kanamycin and the absence of Stx2e (95% CI, 0.08–0.43, P<0.0001) and AIDA-I (95% CI, 0.04–0.52, P=0.002) (Table 4). Otherwise, the average score of VGs between susceptible and resistant strains was different. For example, the difference in the average score of VGs was 0.8 for ceftiofur-susceptible/resistant strains and 1.1 for doxycycline-susceptible/resistant strains, whereas it was 1.9 in the case of kanamycin-susceptible/resistant strains.

, 2004). The vast majority of bacteria in most natural, industrial, and clinical environments

live in biofilms and not as free-living or ‘planktonic’ cells that are commonly studied in the laboratory. Biofilms play a key role in the pathogenesis of many bacterial infections (Parsek & Singh, 2003). Many bacteria and pathogens utilize a biofilm strategy Anti-infection Compound Library concentration to survive inhospitable conditions and cause disease, including Listeria monocytogenes, Salmonella, Shigella, Staphylococcus aureus, Escherichia coli, and Enterobacter (Bower & Daeschel, 1999; Stepanovic et al., 2004; Hanning et al., 2009; Holmberg et al., 2009; Jain & Agarwal, 2009; Yamanaka et al., 2009). Current research has shown that bacteria in a biofilm have increased resistance to host defenses and antimicrobial agents, making most biofilm infections difficult or impossible to be eradicated (Donlan & Costerton, Selleck Venetoclax 2002; Grenier et al., 2009). However, the relationship between virulence and biofilm formation ability, and whether biofilms can exhibit altered virulence factors, has not been investigated. Therefore, the objective of this study was to determine whether biofilm cells can alter adherence, virulence, gene expression, and immunogenicity compared with planktonic cells, using an SS2 virulent strain and an avirulent strain. Three SS2 strains, two virulent and one avirulent, were used in this study. ZY05719 was isolated in Ziyang,

China, in 2005 and HA9801 was isolated by our laboratory in Jiangsu, China, in 1998. T15, the SS2 avirulent strain, was donated by Dr H. Smith (DLO-Institute for Animal Science and Health, the Netherlands)

(Vecht et al., 1997). All SS2 strains were grown in Todd–Hewitt broth (THB) at 37 °C. Planktonic cells and biofilm cell populations were investigated in this study. The collection of different cell suspensions was performed according to the method described previously (Hanning et al., 2009; Wong et al., 2010), with a few modifications. Briefly, for biofilm cultures, SS was grown in THB Exoribonuclease medium supplemented with 1% fibrinogen in 100 mm polystyrene Petri dishes at 37 °C for 24 h. The supernatant was then removed and the plates were rinsed twice with phosphate-buffered saline (PBS, pH 7.2). Biofilms were detached by scraping and sonicated for 5 min (Bransonic 220; Branson Consolidated Ultrasonic Pty Ltd, Australia). All pelleted cultures were washed twice by resuspending pellets with vortexing; biofilm cells were collected by centrifugation. SS planktonic cells were grown in the same culture medium at 37 °C in a rotary shaker (180 r.p.m.). Planktonic cells were pelleted and washed as described in the biofilm cultures above. The production of biofilms by SS was tested using the protocol described by Grenier and colleagues, with a few modifications (Bonifait et al., 2008; Grenier et al., 2009). Briefly, an overnight culture of SS was diluted to an OD600 nm of 0.2 with fresh THB medium supplemented with 1% fibrinogen.

We wish to understand the evolution of BXW and the genetic basis

We wish to understand the evolution of BXW and the genetic basis for the differing host specificities between Xcm, a pathogen of banana, and its close relative Xvv, a pathogen of sugarcane. Genetic differences may also reflect adaptations for epiphytic fitness and for dispersal, perhaps via insect vectors (Tinzaara et al., 2006; Mwangi et al., 2007; Shimelash et al., 2008) rather than virulence factors per se. Recent developments in DNA-sequencing technology provide opportunities

for rapid and cost-effective comparative genomics studies MK-1775 in vitro (MacLean et al., 2009). We used the ‘Next Generation’ Illumina Solexa GA technology (Bentley et al., 2008) to generate draft genome sequences for banana-pathogenic Xcm NCPPB 4381 (Xcm 4381) and for the closely related Xvv NCPPB 702 (Xvv 702), which is not pathogenic on banana. Sequence analysis revealed several genetic differences between these two strains

that might be important for host specificity, virulence and ABT-199 purchase epiphytic fitness, including differences in the repertoires of secreted and translocated effector proteins, type IV pili (TFP) and enzymes for lipopolysaccharide biosynthesis. Xcm 4381 was originally isolated from banana in Uganda 2005. Xvv 702 was originally isolated from sugarcane in Zimbabwe in 1959. We obtained both strains from the National Collection of Plant Pathogenic Bacteria (NCPPB) at the Food and Environmental Research Agency (FERA, York, UK). Genomic DNA was prepared from cultures grown in NYGB (Nitrogen Yeast Glycerol Broth) medium using a Puregene Genomic DNA Purification Kit (Gentra Systems Inc., Minneapolis) and sequenced using the Illumina GA sequencing system. Illumina

sequencing of genomic DNA and sequence assembly were performed as described previously (Studholme et al., 2009). We used maq (Li et al., 2008), blast (Altschul et al., 1990) and mummer (Delcher et al., 2002) for sequence alignment of short reads, contigs and whole genomes, respectively, and cgview (Stothard & Wishart, 2005) for visualizing the alignments. splitstree (Huson, 1998) was used to build and draw phylogenetic trees. We deposited the draft genome data in GenBank under accession numbers ACHT00000000 (Xcm 4381) and ACHS00000000 (Xvv 702). We generated 5 052 905 pairs of 36-nucleotide reads from Xcm 4381; that is a ZD1839 datasheet total of 363 809 160 nucleotides, representing approximately 72 times 5 megabases, the typical genome size for Xanthomonas species. From Xvv 702, we generated 2 913 785 pairs of 36-nucleotide reads; that is a total of 209 792 520 nucleotides, representing approximately 42 times the expected genome size of 5 megabases. We assembled the Illumina data using the velvet short-read assembly software (Table 1). The genome sequences of Xcm 4381 and Xvv 702 shared significantly greater nucleotide identity with each other than with the genome of any other sequenced Xanthomonas genome (Table 2).

Pro-active screening for intended travel activities can identify

Pro-active screening for intended travel activities can identify future VFR travelers and ascertain potentially high-risk itineraries, thereby enabling PARP activation education regarding the importance of accessing competent pre-travel medicine services. Immigrants from low-income countries frequently travel with their families to their place of origin to visit

friends and relatives (VFRs), and account for a significant proportion of international travelers.1,2 Compared with other travelers, VFRs are at greater risk of contracting many travel-related illnesses,3 in part because of insufficient use of preventive travel medicine services.1–5 In the United States, healthy children often access health-care systems for routine health exams, and these encounters afford an opportunity to screen for anticipated international travel. We surveyed immigrant families (parent’s country of birth located in a malaria-endemic zone) to determine the frequency of impending travel and to evaluate for factors associated with these travel plans. learn more Bronx-Lebanon Hospital Center is a 958-bed teaching hospital. It is

one of the largest outpatient health-care providers in the South and Central Bronx. The Bronx is one of the most diverse counties in the United States with about 32.7% of its 1.4 million residents foreign-born.6 Although 75.1, 8.3, and 7.9% of the foreign-born in the Bronx were born in Latin America, Africa, or Asia, respectively, there is a large West-African community within the immediate catchment Orotidine 5′-phosphate decarboxylase area of the Bronx-Lebanon Hospital Center.6 The main pediatric outpatient clinic located in the hospital building provides routine general health care for children from birth to 21 years of age (15,000–18,000 annual patient visits); 65% of the families are

of Hispanic and Latino and 10% to 15% of West-African heritage. Parents were approached in the waiting areas with copies of the Centers for Disease Control and Prevention-malaria endemic regions maps between September and December 2006.7 Parents who were born in a malaria-endemic country and presented to the clinic with one of their children for a routine pediatric health maintenance visit were eligible for participation. After signing an informed consent, a 20-item standardized questionnaire on anticipated travel activity and malaria-relevant knowledge, attitude, and practices (KAP) was administered by a study investigator. Parental factors associated with plans to travel with their child within 12 months from the routine pediatric outpatient visit were investigated using logistic regression. Variables considered in the multivariable model were gender, age, country of birth, period of stay in the United States since immigration, education, access to Internet, history of previous travel to country of origin, number of children, and residence of at least one child abroad. Statistical significance was set at p < 0.05, two-tailed.
