Inverse PCR primers amplifying the rest of the plasmid molecule w

Inverse PCR primers amplifying the rest of the plasmid molecule were designed, and after the amplification reaction, we obtained a product of about 900 bp. No ORF was found on this PCR fragment, but comparison with the GenBank database showed considerable homology (80%) to the plasmid pSRD191 on a DNA

stretch of about 450 bp downstream of the gene for replication protein. In addition to this, we detected limited homology to other plasmids from S. ruminantium, particularly to pONE429 and pONE430, pSRD192, pS23 (M86247) and pJJM1 (Z49917), which was mainly found around the location of SRSR elements of plasmids. This plasmid was designated pSRD77, and its complete nucleotide sequence was found to be 1470 bp in length with an overall GC

content of 46.5% and one open reading frame at nucleotides stretching from 260 to 790 encoding a putative replication protein belonging to RepL family Protein Tyrosine Kinase inhibitor of replication proteins. Studying plasmid selleck kinase inhibitor rep modules is a good approach to assess plasmid biodiversity and/or the evolution of these molecules (Guglielmetti et al., 2005), especially in the case of RCR plasmids that are made as interchangeable gene modules (Novick, 1989). The replication modules of RCR plasmids are made up by the gene encoding for the initiator protein (Rep) and sequences with high secondary structures containing both the binding- and nick-site for the initiator (double-strand origin, dso). Based on similarities of rep modules, RCR plasmids have been divided into several groups, but these groups usually do not correlate with similarities in plasmid single-strand origins (sso), region where replication of the lagging strand begins. High homologies between two different plasmids limited to their rep or other gene modules suggest that shuffling of modules has taken place during plasmid evolution. In this work in a PCR-based experiment, we analysed the genetic organization of putative plasmid rep modules of several S. ruminantium strains. A local collection of strains was included Clostridium perfringens alpha toxin in this study. However, it was

shown that plasmids isolated at different parts of the world shared striking similarities either in the organization of their rep modules or their whole genome (pONE-type vs. pSRD-type plasmids). pSRD-like plasmids were found to be widely distributed in our local set of strains, even though considerable structural instability of these plasmid molecules, respectively, their rep modules were observed in our experiments. While highly conserved rep genes were found among different S. ruminantium strains, in noncoding regions surrounding these genes, structural instabilities including deletions, insertions and other sequence alterations were seen. Selenomonas ruminantium Sequence Repeats (SRSR) sequence elements were found to be highly conserved and widespread among S. ruminantium plasmids originating from various ruminants and geographical locations.

8 per 100 persons Nearly one-third (32%) reported at least one E

8 per 100 persons. Nearly one-third (32%) reported at least one ED visit in the 6 months preceding the interview. Of those visiting the ED, the median was 1 visit per person (range 1–12). Of those with an ED visit, 46% made more than one visit in 6 months. Per patient report, reasons for the most recent ED visit were (1) to treat an Barasertib HIV-related illness (30%), (2) to treat a non-HIV-related illness (45%), (3) to treat an accident (14%), (4) for drug- or alcohol-related reasons (3%), and (5) for pregnancy (0.3%), with 8% missing. For the

most recent ED visit, over three-quarters (77%) were self-referrals, and only 22% of visits were a result of provider referral. For the most recent ED visit, 26% of those seeking emergency care for HIV-related illness were referred to the ED by the provider, and 22% of those seeking care for non-HIV-related illness were referred by the provider, a nonsignificant difference. Table 3 presents results of a logistic regression analysis of factors associated with any ED visit, conducted on 913 patients with complete data. High levels of pain (third

or fourth quartile), having more than seven primary care visits in the last 6 months, current or former illicit drug use, Medicaid insurance, and female gender remained CAL-101 nmr associated with ED utilization when other variables were controlled. Clinical variables – such as CD4 cell count, HIV-1 RNA, or HAART usage – were not significantly associated with any ED utilization. Thirty-nine per cent of patients who visited the ED (n=121) were subsequently admitted to the hospital from the ED on at least one occasion. The probability of having an admission from the ED was associated with the number of ED visits, rising from 32% of those with one ED visit, to 41% of those with two ED visits, to 67% of those with three or more

visits (results not shown). Table 4 reports results of a multivariate ifenprodil logistic regression of any in-patient admission from the ED (n=280). The odds of admission to the hospital from the ED were greater for patients who made six or more primary care visits vs. three or fewer. Patients with CD4 counts <200 cells/μL were more likely to be admitted than those with CD4 counts >500 cells/μL. Patients reporting the highest level of pain also reported relatively high odds of admission from the ED, although the set of variables representing pain quartiles was not jointly significant. Patients who were retired had higher odds of being admitted from the ED than patients who were employed, but the overall effect of employment status on in-patient admissions was not significant. ED utilization was high in this multiclinic, multistate sample of HIV-infected patients. In this study, 32% visited the ED once or more within 6 months, and the 6-month ED attendance rate was 62.8 per 100 persons. Inspection of HIVRN medical record data showed that the 1-year visit rate was approximately twice the 6-month rate.

Enzyme activity was measured based on the determination of α-keto

Enzyme activity was measured based on the determination of α-ketobuty rate resulting from ACC cleavage by ACC deaminase (Penrose & Glick, 2003). Pseudomonas putida UW4 and Mesorhizobium sp. MAFF303099 were used as a positive and negative control, respectively. The region of the genomes from M. loti R7A, Mesorhizobium sp. MAFF303099, M. ciceri bv. biserrulae WSM1271, M. australicum WSM2073T, and M. opportunistum WSM2075T that contain the acdS gene were analyzed to determine

the acdS gene ‘neighborhood’. Talazoparib concentration The intergenic regions upstream of the acdS gene in M. loti R7A, Mesorhizobium sp. MAFF303099, M. ciceri bv. biserrulae WSM1271, M. australicum WSM2073T, and M. opportunistum WSM2075T were examined for putative upstream activator sequences (UAS). Putative NifAUAS (5′-TGT-N9–11-ACA-3′) (Alvarez-Morales et al., 1986; Buck et al., 1986; Morett & Buck, 1988) were searched in the immediate upstream region of the acdS genes using FUZZNUC (, a Web-based program of the European Molecular Biology Open Software Suite (EMBOSS) (Rice et al., 2000). The acdS, nifH,

nodC, and 16S rRNA gene sequences (Table 1) were analyzed using bioedit v. (Hall, 1999) and aligned with muscle (Edgar, 2004). To obtain the best substitution model for the construction of the phylogenetic trees, the resulting acdS, nifH, nodC, and 16S rRNA gene alignments were learn more analyzed with jModeltest (Posada, 2008). The best substitution model for each phylogenetic analysis was chosen based on the lowest Bayesian Information Criteria and Akaike Information Criteria values. All phylogenetic trees were constructed with mega v.5.05

(Tamura et al., 2011) using the maximum likelihood method and the corresponding best substitution model selected. A bootstrap analysis of 1000 replicates was conducted for every phylogenetic Venetoclax analysis. Genes encoding putative ACC deaminase were detected in 10 of 12 Mesorhizobium type strains, as well as in all 18 chickpea Mesorhizobium isolates studied in this work (Table 1). In Mesorhizobium huakuii CCBAU2609T and Mesorhizobium amorphae ACCC19665T, the ACC deaminase gene was not detected by either PCR or Southern hybridization. Southern hybridization showed that only one copy of the acdS gene is present in most of the acdS+ Mesorhizobium type strains (Supporting Information, Fig. S1). All Portuguese chickpea mesorhizobia showed one copy of the acdS gene (data not shown). In these isolates, the acdS gene is present in a fragment of about 8 kb, similar to the fragment obtained from M. ciceri UPM-Ca7T after total DNA digestion with BamHI. Most Mesorhizobium strains used in this study possess an acdS gene; however, ACC deaminase activity under free-living conditions was not detected in any of these strains (Table 1). The acdS gene sequences here obtained share high identity (84–99%) with the previously described acdS gene of Mesorhizobium sp. MAFF303099.

diazotrophicus showed significant differences in the endogenous r

diazotrophicus showed significant differences in the endogenous reduction levels of the cytochromes c. While the cytochromes appeared fully reduced in this website ADHa (Gómez-Manzo et al., 2008), the endogenous reduction levels in ADHi

were low (trace a, Fig. 2). Dithionite (trace b, Fig. 2) but not ethanol (not shown) caused a dramatic increase in the reduction levels of ADHi. To assess the number of cytochromes c that participate in the intramolecular electron transfer that takes place in the ADHi complex, the enzyme ‘as prepared’ was carefully titrated to its full reduced state with a 100 mM dithionite in 100 mM potassium phosphate buffer at pH 6.0 (not shown) and then, successively oxidized with the hydrosoluble quinone-2 (Q2) (trace c in Fig. 2). The data showed that roughly 90% of the ferrocytochrome c content of the enzyme was oxidized as revealed by the major decrease in wavelength signals at 419, 523, and 553 nm. Although catalysis by the ADHi enzyme was severely limited, the intramolecular electron transfer sequence

from the cytochromes c centers to the Q2 electron acceptor is not impaired. The presence of PQQ in ADHi was confirmed by EPR (Fig. 3a) and fluorescence spectroscopy (not shown), as well as by HPLC analysis (Fig. 3b). The intensity of the signal shown by ADHi (as purified) in EPR was rather low (not shown) as compared to that obtained for the ‘as purified’ ADHa complex of Ga. diazotrophicus (Gómez-Manzo Anti-infection Compound Library et al., 2010); however, after addition of dithionite to sample and recording the EPR spectrum of ADHi, a more intense signal was obtained (Fig. 3a). This suggested that the PQQ prosthetic group in ADHi is mainly in

its oxidized state, which is in contrast to the ADHa complex where PQQ was detected in its semiquinone form. Recently, we demonstrated the presence of a new prosthetic Fossariinae group: [2Fe-2S] in subunit I of ADHa (Gómez-Manzo et al., 2010). The determination of the acid-labile sulfurs by the method of Beinert (1983) showed the presence of 2.02 ± 0.1 sulfur atoms per ADHi heterodimer, which is similar to the amount of sulfur previously determined in the active ADH heterodimer (Gómez-Manzo et al., 2010). However, the EPR spectrum of the purified ADHi ‘as prepared’ showed no signal corresponding to the iron-sulfur cluster (not shown). As this latter form is a diamagnetic species, we conclude that this cluster in ADHi must be in the oxidized form. The redox state of the PQQ in ADHi was further analyzed by HPLC. To this purpose, PQQ was extracted from the purified ADHa and ADHi complexes by a methanol-ethanol mixture. For ADHa, a single peak with a retention time of 4.5 min was obtained, whereas the PQQ extracted from ADHi produced a single peak with a retention time of 6.8 min (Fig. 3b). Commercial PQQ (Sigma; PQQH2) showed a retention time of 4.1 min that shifted to 6.8 min after oxidation with ammonium peroxydisulfate (Fig. 3c). This result is indicative that PQQ in ADHi is present in its oxidized state (retention time 6.

The resulting

The resulting

plasmid pQEMip was introduced into the M15 strain by electroporation. The pHATPrtA (Table 1) and pHATDHFR (Clontech) plasmids Caspase-dependent apoptosis were introduced into the JM109 strain. The total, extracellular and periplasmic proteins of strains NK2699/pR3MipH6 and NK2699/pR3PrtA were prepared using the method described previously (Zang et al., 2007). The outer membrane fraction proteins were prepared as described (Leuzzi et al., 2005). The BacterioMatch® II two-hybrid system (Stratagene) was used according to manufacturer’s instructions. The two plasmids, pBT and pTRG, containing the fusional prtA and mipXcc genes without signal peptide coding sequences, were used to simultaneously transform BTHrst (reporter strain). Within the reporter gene cassette, protein-protein interactions were screened for activation of addA and HIS3 genes. This resulted in resistance to

streptomycin (12.5 μg mL−1) and 5 mM 3-amino-1,2,4-triazole (3-AT). Release of periplasmic proteins in situ was achieved using the chloroform vapor treatment method described by Ames et al. (1984) with minor modification. After removing the cap, the plate with grown Xcc colonies was laid upside down above a disk containing 2 mL chloroform and incubated for 1 min. In vitro Western blot and far-Western blot assays were performed as described by He et al. (2006). The preparation of recombinant (His)6-MipXcc, HAT-PrtA and HAT-HDFR protein was performed as described previously (Zang et al., 2007). A quantity of 10 μg (His)6-MipXcc and 100 μL of periplasmic fraction (or extracellular fraction) were added into 10 mL of 50 mM Tris–HCl (pH 8.0). The solution was mixed FDA approved Drug Library cell line well and incubated at 28 °C for 4 h. The protease activity of the mixture was measured by azocasein assay (Charney & Tomarelli, 1947). First, azocasein (Sigma) was dissolved in 100 mM Tris–HCl (pH 8.0) and used as a substrate. Then 100 μL of the rescue mixture was mixed with an equal volume of the substrate in a 1.5-mL EP tube. After incubation at 28 °C for 1 h, 800 μL of ice-cold 5% trichloracetic acid was added. The tube was then centrifuged for 15 min at 20 800 g. Meanwhile, 500 μL of supernatant was mixed with equal volume of 0.5 M NaOH, and A440 nm. One unit of protease activity was defined as an increase of 1 OD unit at 440 nm in 30 min. The whole experiment was repeated three times. The Xcc strain 8004 genome contains six ORFs encoding extracellular proteases such as XC_1514, XC_1515, XC_3376, XC_3377, XC_3378, and XC_3379 (Qian et al., 2005). One of them, XC_3379, has already been characterized as prtA, which encodes the major extracellular protease PrtA (also known as Prt1). This enzyme is responsible for almost all extracellular protease activity of Xcc strain 8004. Inactivation of prtA leads to almost complete loss of extracellular protease activity (Tang et al., 1987; Dow et al., 1990; Barber et al., 1997).

This questionnaire is dichotomic; any answer expressing lack of adherence is considered to indicate nonadherence. The presence

of depression was evaluated using the Beck Depression Inventory, Second Edition (BDI-II) [20], which is an instrument made up of 21 items designed to identify depressive symptoms and quantify their intensity. In each item, the option that best fits the patient’s mental state in the previous 2 weeks is selected from four alternatives listed in order of lesser to greater severity. Each item is scored from 0 to 3, and adding the scores together gives learn more a final score that ranges from 0 to 63. Categories of severity are defined as follows: 0–13 points, minimal or no depression; 14–19 points, mild depression;

20–28 points, moderate depression, and 29–63 points, severe depression. This instrument has been validated for the Spanish population with high internal Romidepsin chemical structure consistency (α coefficient of 0.87) [21]. BDI-II is one of the most widely used instruments for evaluation of depression in HIV-infected people [22]. Patients were contacted in order to schedule a personal interview, during which a trained interviewer administered the previously described questionnaires. Statistical analysis was carried out as follows. A descriptive profile analysis was performed on the sample, the results of which are expressed Bay 11-7085 as mean ± standard deviation, frequencies

and percentages. Subsequently, the association between variables was studied using χ2 test with Fisher’s exact test and Student’s t-test with Bonferroni’s adjustment for multiplicity. An analysis of variance (ANOVA) was used to compare differences between groups when required. Finally, logistic regression analyses were carried out using PHS and MHS as dependent variables, with patients considered to have a poor quality of life if their PHS and/or MHS was at or below the 25th percentile of the distribution. Independent variables were those with significant results in the univariate analyses, in addition to age and sex, in order to obtain a logistic regression model that permitted study of predictive variables related to PHS and MHS. The number of variables included in each model was six (one variable for every 20 patients to avoid interactions). Data were analysed using spss v.15.0 (SPSS Inc., Chicago, IL, USA) and graphics were created using the GraphPad Prism 5.0 application (La Jolla, CA, USA). Values were considered significant at a P-value ≤0.05. The HRQL analysis was carried out according to the recommendations of the original authors [23].

, 2009). LB

medium was supplemented with ZnCl2 (25 μg mL−1), and plates were incubated at 37 °C for 48 h. Bacitracin minimum inhibitory concentrations (MIC) were detected by Etest (Bio-Mérieux) on Müller-Hinton plates swabbed with an inoculum of 0.5 McFarland and incubated at 37°C for 24 h. Overnight cultures were diluted to OD 0.05 in LB media containing 0.05 μg mL−1 tunicamycin (AG Scientifics). OD measurements were taken hourly for 8 h. Cell walls and WTA were prepared as previously described (Majcherczyk et al., 2003). The amount of WTA was indirectly quantified by determination of the cell wall phosphorus content (Ames & Dubin, 1960). Experiments were performed two to four times with three technical replicates per sample. LCP proteins are essential for optimal cell separation (Over et al., 2011). The severe cell division defects of double and triple LCP mutants resemble GS-1101 order those resulting from the depletion of essential peptidoglycan biosynthesis enzymes or inhibition of WTA synthesis, which both trigger VraSR signal transduction and

induction of the CWSS (Gardete et al., 2006; Sobral et al., 2007; Balibar et al., 2009; Blake et al., 2009; Campbell et al., 2012). The most sensitive indicator of staphylococcal CWSS activation is the sas016 gene, as demonstrated previously in Northern blot, promoter-luciferase fusion and microarray studies; however, its function is still unknown (McAleese et al., 2006; Dengler et al., 2011). check details selleck products We therefore determined the basal CWSS transcription levels of single, double and triple LCP mutants and compared them to those of the parent strain MSSA1112 using a probe against the CWSS gene sas016. Northern blots showed that sas016 transcription was detectably higher in single LCP mutants than in the wild type, with highest levels of transcription in the Δsa0908 mutant (Fig. 1a). Transcript levels were further increased in double LCP

mutants, Δsa0908/msrR, Δsa2103/msrR and Δsa2103/sa0908, and were extremely high in the LCP triple mutant (Fig. 1a). To compare and quantify CWSS expression at different growth stages, a promoter-luciferase reporter construct containing the sas016 promoter (psas016p-luc+) was used as previously described (McCallum et al., 2011). Figure 1b shows the luciferase activity levels measured in relative light units (RLU) in the wild type and LCP mutant strains at the time points indicated. The right graph shows the corresponding OD values of the cultures at each sampling point. To confirm patterns of CWSS upregulation, expression of the autoregulatory vra promoter from the vraSR operon was also measured, using the promoter-luciferase fusion pvrap-luc+ (Supporting information, Fig. S1).

However, PMM1416 has been seen to be upregulated during both P and light stress, indicating a general stress response role for this particular protein (Coleman et al., 2006). The levels of alkaline phosphatase, PhoA, were c. 28-fold more abundant in the stressed cultures, whereas the porin PhoE was c. 50-fold more abundant (Fig. 2a). At the transcriptomic level after 48 h, the regulated levels were almost at parity (Martiny et al., 2006), suggesting the differential production of both PhoE and PhoA over extended starvation periods. Increased alkaline phosphatase activity has been measured previously for oceanic picocyanobacteria under P stress

(Moore et al., 2005; Tetu et al., 2009) and in Synechocystis sp. PCC6803 (Gan, 2006), NVP-BKM120 manufacturer and so our results are in line with these observations. The structure and functioning of the MED4 photosynthetic apparatus is affected through extended P starvation (Fig. 3). Seven proteins were recognized as differentially abundant (Fig. 2b). Proteins that were less abundant than the control were those associated with chlorophyll binding and light harvesting (e.g. Pcb and CP43 within PSII). Interestingly, this observation has also been identified

recently at the transcriptomic level in Synechococcus WH8102 when subjected to extended P stress (Tetu et al., 2009). PsaA, which is known to be an electron acceptor in PSI, is also less abundant as well as the plastocyanin docking protein PsaF. PsaA is also a vital part of the photosynthetic

electron transport chain (PETC), and binds almost 100 chlorophyll molecules, making it an essential light-harvesting protein Methamphetamine in PSI (Barber, 2001), specifically as MED4 has only one copy of the pcb gene, which is associated exclusively with PSII (Fig. 3) (Rocap et al., 2003). From this, we conclude that the cell reduced its photosynthetic capabilities. This would directly reduce UV photodamage and oxidative stress from reactive oxygen species produced as a byproduct of water splitting at the oxygen-evolving complex at the base of PSII. This conclusion is supported by the observation that the known antioxidants, thioredoxin (TrxA) and thioredoxin peroxidise (tpx), are not significantly differentially abundant in the stressed phenotype (Fig. 2d). It is also clear that other essential proteins in the PETC, besides PsaF, are less abundant than the P-replete control. PsaF and ferredoxin-NADP oxidoreductase are downregulated, which strongly suggests that the cell is attempting to reduce certain reductive energy production processes, specifically NADPH generation, which in turn indicates a general metabolic slowdown. It is interesting to note that essential protein subunits of the ATP synthase complex are unaffected by long-term exposure to P deprivation, which suggests that ATP was produced normally.

, 2004). The AAV may be unique in producing widespread transduction following intraventricular delivery. The pattern of transduction suggests that the virus follows the flow of the cerebrospinal fluid through the subarachnoid space (Passini & Wolfe, 2001). At just 20–25 nm in diameter, the small size of AAV particles may facilitate their dissemination throughout the brain. In contrast, at 100+ nm in diameter, lentivirus injected at the same age transduced only the ventricular surface and choroid plexus (Watson et al., 2005). Although not yet empirically

tested, the still larger herpes simplex virus (180–200 nm) might also be expected to show little transduction PLX4032 research buy outside the ventricle. Size is clearly not the only factor influencing viral spread as, unlike AAV1, 2, 6, 8, and 9 (our data and Passini & Wolfe, 2001; Passini et al., 2003; Broekman et al., 2006; Cearley et al., 2008),

AAV5 transduction does not advance much beyond the injection site (Watson et al., 2005). The distribution of cellular receptors and their affinity for different AAV serotypes may also contribute to viral spread. AAV5 and, to a lesser extent, AAV1 (Fig. 6) appear to bind strongly at the ventricular surface, leaving fewer particles to enter the parenchyma. Because of their varying receptor affinities, viral transgenesis also opens the possibility of harnessing serotype specificity to target distinct cellular populations. We demonstrate that AAV1 favors superficial layers of the cortex, RXDX-106 purchase whereas AAV8 transfects more evenly across layers. AAV6 offers improved transduction of cerebellar Purkinje neurons, but works less well in the forebrain. Past work on

neonatal AAV transduction has shown that the serotype strongly Metalloexopeptidase biases which brain regions and cell types are targeted, with select capsid proteins preferring inhibitory neurons, astrocytes, or oligodendrocytes (Broekman et al., 2006; Cearley et al., 2008; Nathanson et al., 2009). Although the precise mechanism of AAV transduction is not well understood, receptors for several serotypes have been identified, including the 37/67 kDa laminin receptor (AAV8), platelet-derived growth factor receptor (AAV5), αVβ5 integrin (AAV2), hepatocyte growth factor receptor (AAV2), and fibroblast growth factor receptor [AAV2 and 3; reviewed in Akache et al. (2006)]. Specific sialic acid and heparan sulfate linkages also contribute to AAV tropism, and binding of several serotypes can be eliminated by enzymatic deglycosylation of cultured cells (AAV2-5). With over 100 AAV variants isolated to date, the repertoire of possible transduction patterns has yet to be fully exploited (Wu et al., 2006), and rational engineering of AAV glycoproteins and their cell-surface receptors promises even greater control in the future (Wang et al., 2011).

Since 2007, medical data is more structurally collected,

Since 2007, medical data is more structurally collected,

and data on the country of birth of both parents HDAC inhibitor drugs have been included in the data collection and entered in the database. According to the Dutch guidelines published by the National Coordination Centre for Travelers’ Health Advice (LCR), travelers to the KSA are given health recommendations in addition to the mandatory meningitis vaccination; this advice includes information about vaccinations for hepatitis A (travelers who are born and raised in countries where hepatitis A is endemic are considered immune); typhoid fever (for travel more than 2 weeks); and the trivalent diphtheria, tetanus, and poliomyelitis vaccine (dTP). Because immigrants from countries where hepatitis B virus (HBV) is endemic who now live in a country where HBV is not endemic are a specific risk group for viral hepatitis B,5 BAY 73-4506 chemical structure since 2009 this group has also been offered hepatitis B vaccination. Hepatitis A vaccination and updating vaccination

against dTP is recommended for every traveler that will visit a country where such diseases are endemic, including KSA. Most people in this group are born and raised in a country endemic for hepatitis A. Therefore, according to Dutch guidelines, most are considered immune, vaccination is not recommended, and uptake of hepatitis A vaccination cannot be evaluated. For dTP, travelers who have never been vaccinated, whose vaccination status is uncertain, who have received incomplete diphtheria, tetanus, or polio vaccination

series, and whose most recent vaccination has been given more than 10 years ago are advised dTP. As dTP is the most advised vaccination in this group, and because it is very rare that people choose to accept one, but reject another recommended vaccination, dTP acceptance is used as a “proxy” for the willingness to accept recommended vaccinations. Endonuclease In this study, all data of the Muslims who visited the PHS before travel to Mecca are extracted from the database and analyzed retrospectively. Over the years from 2001 to 2009, the characteristics are described and trends are analyzed by age, gender, duration of travel, and time of visit to the PHS before departure. For the years 2007 to 2009, predictive factors for the acceptance of advised dTP vaccination are analyzed. Factors tested are age, gender, status as first- or second-generation immigrant, number of medical disorders, and specific disease category. Statistical Package for the Social Sciences (SPSS) version 17.0.2 software program (SPSS, Inc., Chicago, IL, USA) was used to carry out all analyses. Multiple regression analyses were performed in two models. In model one, the number of disorders was analyzed; in model two, the kind of disorder was analyzed. These two models are not taken together to exclude duplicates. To calculate the risk factors for different outcomes, odds ratios (ORs) and 95% confidence intervals (CIs) were obtained. Differences with a p value equal to or lower than 0.
