A number of other limitations exist in our study. The method we used to select operators may have excluded several operators. Those without a website were clearly overlooked. So too were five operators who did not respond to our initial contact. However, we believe that a reply rate of 83% is representative. We did not actively seek out reasons for the operators’ decisions. Although many operators did provide unprompted explanations, these may not represent all of those who took part.

Nevertheless, we believe that the quotes cited here are representative of the vast majority of operators contacted. It was unclear from our investigations whose opinion drove operator policy and whether it was a company or guide choice on which medications to take. In our inquiries, we did not actively question what mandatory medical training see more was given to guides or what other medical kit was available to counter high altitude illness. In conclusion, this study reveals that a large number (48%) of commercial UK-based expedition operators do not provide drugs for the treatment of AMS, HACE, and HAPE on expeditions to Kilimanjaro, Aconcagua, and EBC. Although there is limited case law for deaths at high altitude it is not plainly documented how many minor injuries and trips are cut short for those injured and not,

Vorinostat concentration leading to a disappointing expedition,

due to high altitude illnesses. With Resveratrol commercial expeditions becoming increasingly popular, we believe that this has the potential to increase morbidity and mortality from high altitude illnesses. We recommend that a clear set of guidelines are established that provide trained individuals with the means to diagnose and treat high altitude illnesses safely and effectively. As these medications are proven to save lives, it is vital that they are present in expedition medical kits and available to all those who head to altitude. The response from one commercial operator is, we believe, worth following: I do indeed carry all three of those drugs that you mention and I also supply my clients and my staff with specific information on how to use them, when to use them and how to diagnose the difference between AMS, pulmonary and cerebral oedema. I consider this vital to my role as a provider of holidays to high altitude. I also ensure that my porters have access to these and other medicines necessary for any wilderness treks. D. H. is employed by a Commercial Expedition Company (Jagged Globe) as their medical advisor which involves educating the staff and advising clients on medical matters. He is also honorary medical Advisor to the British Mountaineering Counsel. The other authors state they have no conflicts of interest to declare.

These data confirmed that the identified pqqABCDEF operon was ess

These data confirmed that the identified pqqABCDEF operon was essential, at minimum, for several steps of the PQQ biosynthetic pathway in P. ananatis. However, it cannot be excluded that some additional genes from other loci of the P. ananatis SC17(0) chromosome participated in PQQ synthesis as well. To test this possibility, the cloned pqq operon was transferred from P. ananatis SC17(0) into E. coli. www.selleckchem.com/products/GDC-0941.html In E. coli, the primary pathway for glucose consumption is the phosphoenolpyruvate/carbohydrate phosphotransferase system (PTS) (for a review, see Deutscher et al., 2006). The GDH-mediated pathway

in this organism does not work because of the absence of the PQQ biosynthesis route. In E. coli, mGDH is synthesized only in apoenzyme form; however, the holoenzyme can be formed in the presence of exogenous PQQ. We expected to observe a similar effect after integration of the P. ananatis putative pqq operon into the E. coli chromosome. To support this hypothesis,

one copy of the pqq operon was introduced into the double mutant strain, with inactivated PTS and the mannose permease Alectinib mouse system. The strain used as a recipient, named MG1655-2Δ, is unable to grow on the glucose minimal medium because of the absence of effective glucose uptake. Synthesis of PQQ in the MG1655-2Δ-pqq strain, which has pqq operon integrated at the φ80attB site, could lead to direct oxidation of glucose to gluconic acid by PQQ-mGDH. The growth properties of MG1655-2Δ-pqq were compared with those

of the wild-type strain and to MG1655-2Δ, grown with the addition of exogenous PQQ, on the minimal medium with glucose as the sole carbon source. As shown in Fig. 1, integration of the pqq operon resulted in the restoration of MG1655-2Δ-pqq growth on glucose minimal medium. However, MG1655-2Δ-pqq showed a prolonged lag time unlike the wild-type strain or MG1655-2Δ growing in the Lonafarnib in vitro presence of PQQ in the medium (+PQQ). In addition, MG1655-2Δ-pqq grew at a slower rate than MG1655-2Δ under +PQQ conditions; however, it had a higher final OD. Comparison of the growth properties of MG1655-2Δ and MG1655-2Δ-pqq suggests that the introduction of the pqq operon allowed the formation of an active GDH, resulting in the production of gluconic acid from glucose and its further utilization. We attempted to determine whether E. coli strains containing the pqq operon are able to accumulate PQQ in the culture medium. In our experiments, we could detect about 0.25 μg L−1 of PQQ in the assay system. However, no PQQ was observed during MG1655-2Δ-pqq growth on the minimal medium with gluconate as the sole carbon source. It is possible that pqq genes cloned with their native regulatory regions from P. ananatis are poorly expressed in E. coli. Conversely, the P. ananatis SC17(0) strain with the native pqq operon accumulates up to 9 mg L−1 of PQQ.

, 2002; Gonzalez Barrios et al, 2006) Escherichia coli O157:H7

, 2002; Gonzalez Barrios et al., 2006). Escherichia coli O157:H7 harbors QS-regulated virulence genes on a pathogenicity island termed the locus of enterocyte effacement (LEE) (Surette & Bassler, 1998) that is organized mainly into the five polycistronic operons LEE1–LEE5 (Kaper et al., 2004). The first gene in LEE1, LEE-encoded regulator (ler), produces the principal transcriptional activator of the LEE genes (Elliott et al., 2000) and its expression was reported to be positively regulated by both AI-3 and norepinephrine (Sperandio et al., 2003; Jelcic et al., 2008). In patients with E. coli O157:H7 infection,

antibiotic use is generally limited because bacterial cells lysed by antibiotic treatment release learn more an excessive quantity of Shiga toxin, thereby aggravating the patient’s state and resulting in HUS (Wong et al., 2000). To avoid this risk, an antimicrobial treatment that involves attenuation of bacterial virulence by inhibiting QS has been proposed (Ren et al., 2004). Halogenated furanone compounds as QS inhibitors were isolated from marine macroalga, Delisea pulchra (Givskov et al., 1996). Many of the synthesized furanone

derivatives have also been identified as QS inhibitors both in vitro (Martinelli et al., 2004) and in vivo (Wu et al., 2004). However, most of the characterized QS inhibitors have not yet been qualified as chemotherapeutic agents because they are composed MAPK inhibitor of halogens that exert toxic effects in humans. Thus, more efforts should be made to develop safer QS inhibitors from natural products. As a soluble fiber, broccoli (Brassica oleracea) contains a large amount of vitamin C and multiple Amino acid nutrients with potent anticancer properties (Vasanthi et al., 2009). However, the effect of broccoli against infection by pathogenic bacteria has never been reported. In this study, we demonstrate the inhibitory effects of broccoli extract (BE) on bacterial QS using E. coli O157:H7 as a model organism. The in vivo effects of the BE against E. coli O157:H7 infection were also elucidated in a Caenorhabditis elegans killing

assay. Finally, we tested three different flavonoid compounds (quercetin, kaempferol and myricetin) reported to be present in BE (He et al., 2008; Schmidt et al., 2010) in order to gain better insight into the active inhibitory compound in BE. An E. coli O157:H7 strain ATCC 43894 producing Shiga toxins I and II, an avirulent E. coli OP50 strain and Chromobacterium violaceum CV026 were grown in Luria–Bertani broth (LB, 10 g tryptone, 5 g NaCl, 5 g yeast extract L−1) at 37 °C. Vibrio harveyi BB170, an AI-2 reporter strain, was grown at 30 °C with agitation (175 r.p.m.) in the AB medium (Fong et al., 2001). The AB medium consisted of 10 mM potassium phosphate (pH 7.0), 0.3 M NaCl, 0.05 M MgSO4, 0.2% Casamino acids (Difco), 2% glycerol, 1 mM l-arginine, 1 μg mL−1 of thiamine, and 0.01 μg mL−1 of riboflavin. Quercetin, kaempferol and myricetin were purchased from Sigma-Aldridge (St.

There was no

significant difference in sex between the two groups. The difference in age distribution between hepatitis A-positive and hepatitis A-negative individuals (Table 1) was significant (p < 0.0001). The hepatitis A seronegative group was younger than the positive one. More than 75% of seronegatives and less than 50% of seropositives were younger than 36 years. A total of 426 people came from sub-Saharan Africa, 48 from North Africa, 57 from Far East Asia, 23 from the Near and Middle East, 72 from Central and South America and Mexico, and 20 from Eastern Europe (Table 1). The difference in seroprevalence among continents of origin was statistically significant (p < 0.0001). Ninety percent of the people of sub-Saharan

African origin, selleck compound 82.6% of subjects from the Near and Middle East, 81.2% of North Africans, 68.4% of Far East Asians, 56.9% of Latin Americans, PLX3397 and 50% of Eastern Europeans had hepatitis A antibodies. Mean length of stay in a country at risk (available for 589 people) was 22.6 years (range 1–64 years). The difference between the hepatitis A-positive and hepatitis A-negative group in the distribution of duration of residence in a country at risk (Table 1) was significant (p < 0.0001). A longer length of stay was associated with a higher seropositivity rate. Almost three quarters of the positive group (while less than half of the negative group) lived longer than 18 years in a developing country. Multivariate analysis shows that age, length of stay at a country at risk, and the continent of origin predispose to be “naturally” immunized against

hepatitis A (Table 2). Of the 989 individuals to whom serology was recommended, we received only 646 test results. People who did not do the test had several reasons. They did only what was obligatory, did not take recommendations seriously, did not have money or time to Tolmetin do the test. This could represent bias in recruitment. We tested for total or IgG (but not IgM) antibodies against hepatitis A. In theory, acute or recent hepatitis A cases could have been included in the positive group. This would have falsely increased the fraction of “naturally immunized” people. None of the patients had symptoms of acute hepatitis at the time of the interview. Our recommendation of hepatitis A vaccine would not have changed. Multivariate analysis shows that being older, having lived longer in a country of risk, and coming from Africa is associated with an increased probability of being “naturally” immunized against hepatitis A. We found a global seroprevalence of 82.4%. Our study population consisted of immigrants from hepatitis A-endemic countries visiting their country of origin. Seventeen percent of our entire study population and 10, 30, and 44% of people of sub-Saharan African, Far Eastern, and Latin American origin, respectively, had no antibodies against hepatitis A. Many countries with low socioeconomic status are still hyperendemic for hepatitis A.

Other factors on the Rm1021 cell surface, and growth conditions,

presumably regulate attachment and/or growth as a biofilm on polyvinylchloride. Rhizobia are soil bacteria with the capability to establish a symbiotic relationship with legume plants when soil nitrogen is limited. Rhizobial surface polysaccharides play important roles in symbiosis and formation of active nodules. Mutants defective in the production of exopolysaccharides, lipopolysaccharides, and capsular polysaccharides usually show reduced induction of effective nodules, and are particularly GPCR Compound Library manufacturer affected in the process of infection through infection threads (Hirsch, 1999). One of the best-studied exopolysaccharides produced by Sinorhizobium meliloti is succinoglycan (EPS I) (Reinhold et al., 1994), which consists of repeated units of an octasaccharide containing one galactose and seven glucoses, and has characteristic succinyl, acetyl, and pyruvyl modifications. A 25-kb region located in the second symbiotic megaplasmid (pSymB) in S. meliloti clusters the exo–exs genes necessary for the production of EPS I. The roles of most Metformin of these genes have already been defined (Reuber & Walker, 1993). Sinorhizobium meliloti is also capable of producing a second exopolysaccharide known as galactoglucan (EPS II) (Her et al., 1990; Zevenhuizen, 1997), which is synthesized under

conditions of phosphate limitation (as often found in soils) (Zhan et al., 1991; Mendrygal & González, 2000), in the presence of a mutation in the regulatory gene mucR (Zhan Rutecarpine et al., 1989; Keller et al., 1995) or an intact copy of the transcriptional

regulator expR (Glazebrook & Walker, 1989; Pellock et al., 2002). EPS II is a polymer of disaccharide repeating units consisting of an acetylated glucose and a pyruvylated galactose (Her et al., 1990). A 32-kb cluster of genes (the exp genes) also located in pSymB is responsible for the production of EPS II (Glazebrook & Walker, 1989). EPS I and EPS II are synthesized in two different fractions: high molecular weight (HMW) and low molecular weight (LMW). External addition of the LMW fractions of EPS I (trimers of the octasaccharide), and oligomers (15–20 units of the disaccharide) of EPS II, can restore defective infection phenotypes in exopolysaccharide mutants, indicating that the establishment of symbiosis requires the presence of at least one of the LMW forms of either EPS I or EPS II (Battisti et al., 1992; González et al., 1996). Bacterial surface components, such as exopolysaccharides, flagella, and lipopolysaccharides, are important not only in rhizobia–legume symbiosis but also in biofilm formation. Biofilms are defined as microbial communities surrounded by a self-produced polymeric matrix and attached to a surface (Costerton et al., 1995). The major components of biofilms are water (up to 97% of the total volume) and bacterial cells.

1A). Thus, presynaptic terminals of granule see more cells probably express NRX isoforms that could bind to both NL1(−) and LRRTM2. Interestingly, when HA-Cbln1 was applied to HEK293 cells expressing NL1(−),

synaptogenesis was significantly inhibited (Fig. 1A). In contrast, HA-Cbln1 did not affect synaptogenesis observed in HEK293 cells expressing LRRTM2 (Fig. 1A). HA-Cbln1 did not directly bind to HEK293 cells expressing NL1(−) or LRRTM2 (data not shown). LRRTM2 is reported to bind to NRXβ(S4−), which lacks a splice site 4 insert, whereas NL1(−) binds to both NRXβ(S4−) and NRXβ(S4+) (Boucard et al., 2005; Ko et al., 2009). Indeed, presynaptic terminals of cbln1-null granule cells accumulated on HEK293 cells expressing LRRTM2 were preferentially inhibited by NRX1β(S4−)-Fc. In contrast, synaptogenesis induced by NL1(−)cells was preferentially inhibited by NRX1β(S4+)-Fc (Supporting Information Fig. S1). Therefore, we hypothesized that Cbln1 may interact with NRXβ(S4+) expressed at presynaptic sites in granule cells and, thus, specifically interfere with NL1(−)-induced synaptogenesis. To examine this hypothesis, we next expressed GFP-tagged NL1(−) in HEK293 cells and examined whether HA-Cbln1 affected the binding between

NL1(−) and NRX1β(S4+). The extracellular domains of NRX1β isoforms were attached to the Fc fragment of IgG. We confirmed that both NRX1β(S4+)-Fc and NRX1β(S4−)-Fc bound to HEK293 cells expressing Omipalisib nmr NL1(−) (Fig. 1B). Application of HA-Cbln1 to the culture medium Thiamet G specifically and significantly reduced the interaction between NL1(−) and NRX1β(S4+)-Fc (Fig. 1B). These results indicate that Cbln1 interacts with NRX(S4+) and competes with the NL1(−)-NRX(S4+) pathway. To confirm that Cbln1 bound to NRX(S4+), we performed cell-based binding assays, which were previously used for the characterization of interaction between GluD2 and Cbln1 (Matsuda et al., 2010). GluD2 served as a positive control, and GluD2 lacking the NTD (GluD2ΔNTD), to which Cbln1 did not bind,

served as a negative control for the binding assays. At 2 days after transfection, cells were incubated with recombinant HA-Cbln1 for 4 h. Immunoblot analyses (Fig. 2A) showed that HA-Cbln1 bound to HEK293 cells expressing NRX1β(S4+) or GluD2, but not to cells expressing GluD2ΔNTD. Immunocytochemical analyses also showed that HA-Cbln1 bound to HEK293 cells expressing NRX1β(S4+), whereas HA-CS-Cbln1, a trimeric complex that did not possess synaptogenic activities (Matsuda et al., 2010), did not bind (Fig. 2B). Although LRRTMs interact with both NRXα(S4−) and NRXβ(S4−) (Ko et al., 2009; de Wit et al., 2009; Siddiqui et al., 2010), certain NL isoforms bind preferentially to β-isoforms of NRXs. Thus, we examined which isoforms of NRXs interacted with Cbln1 in the cell-based binding assays.

“The increase in the life expectancy achieved following the introduction

of more effective antiretroviral therapy (ART) in recent years now means that the HIV-infected population are for the first time being exposed to the age-related diseases that affect the general population. Nevertheless, the prevalence of these diseases (which include cardiovascular disease, dyslipidaemia, glucose intolerance and diabetes) is higher, and their onset earlier in the HIV population, probably due to the complex interplay between HIV infection, coinfection with hepatitis B and C, and ART. As a result, HIV

physicians are PARP inhibitor now required to adopt a new approach to the management of HIV, which involves screening and regular monitoring of all HIV-infected individuals for the presence of comorbidities and prompt referral to other clinical specialties when required. If this challenge to patient management is to be overcome, it is clear that educating physicians in the diagnosis and treatment of age-associated comorbidities selleck chemicals is essential, either through ongoing programmes such as the HIV and the Body initiative, an overarching independent medical education programme established in 2007 and overseen by an independent Steering Committee, organized and funded by Gilead, and/or through Miconazole internal training. To assist in this process, this article provides an overview of common comorbidities affecting HIV-infected persons and provides practical guidance on their management. The introduction of effective combination antiretroviral therapy (ART) for the treatment of HIV infection means that patients now have much greater life expectancies [1]. However, mortality rates for HIV-infected patients are three to 15 times

higher than those of the general population [2]. While some of this excess mortality can be attributed to immunodeficiency, more than half of these deaths are not AIDS-related [3]. For the first time, HIV-infected patients are being exposed to the age-related diseases that affect the non-HIV-infected population; for example, cardiovascular disease (CVD), dyslipidaemia, glucose intolerance and diabetes. The prevalence of these conditions may be increased by the premature ageing effect of HIV infection on the immune system [4] and may mean that age-related metabolic comorbidities are encountered earlier than in the noninfected population. Progression to severe disease may also be accelerated in HIV-infected patients when compared with the general population as a result of coinfection with hepatitis B virus (HBV) or hepatitis C virus (HCV) and certain lifestyle factors; for example, cigarette smoking and alcohol consumption [1].

“Objectives  Recent studies have identified recruitment of customers at the pharmacy counter as a limiter to successful provision of cognitive services in community pharmacies especially that of experienced customers with refill prescriptions. The aim of the paper is to gain insight into current problems of recruiting. Methods 

A qualitative study was conducted based on semi-structured interviews with 12 participants in a project in 2010 aimed at optimising recruitment of experienced asthma patients for the Inhaler Technique Assessment Service in Denmark. An ad hoc analysis was applied in order to interpret pharmacy staff perceptions of experienced asthma patients in comparison with newly diagnosed patients and to categorise the types of developed recruitment strategies as to whether they reflected a technical or everyday-life perspective on medicine. Key findings  Effective recruitment processes were found to follow a generic pattern which consisted of a special type of opening

question Thiazovivin ic50 followed by providing a justification for the service. The participants perceived that the main difference between experienced and newly diagnosed patients was their degree of knowledge about their condition or correct inhaler technique. Most questions, and especially those related to reasons for motivating the customer to accept the service, were dominated by a professional technical understanding of medicine. In particular, follow-up justification Methocarbamol based on a life-world perspective needs to be developed further. The identified type of communication might prevent some customers from accepting the service as they

are not motivated by technical arguments but rather by how their daily symptoms can be relieved. Conclusions  Pharmacy staff should focus both on adequate opening questions as well follow-up justification when trying to recruit customers for cognitive services. The study might inform future studies on how to create new and more adequate strategies for recruitment of customers for relevant cognitive services in community pharmacies. “
“This study aims to explore physicians’ views of pharmacists’ roles in providing primary care services through community pharmacies in the United Arab Emirates (UAE). A qualitative approach involving semi-structured interviews conducted one-to-one or in group discussions was employed. The interviews explored participants’ views of pharmacists’ primary care services including screening and monitoring of disease, health advice, referral, lifestyle and preventive care, supply of printed information, counselling on medications, patient record keeping, and pharmacist intervention in chronic disease management. Data were analysed using the Framework approach.

Our results indicate that HBD-1-3 and Phd-1-3 do not require PMF for their antibacterial activity. The absence of activity against E. coli in the presence of Na+ and Ca2+ ions is due to not only weakened electrostatic interactions with anionic membrane components, but also involvement of electrochemical

gradients. However, Mg2+ prevents electrostatic interaction of the peptides with the outer membrane resulting in loss of activity. “
“The purpose of this study was to investigate the feasibility of cultivating the biotechnologically important bacterium Streptomyces www.selleckchem.com/products/CP-690550.html griseus in single-species and mixed-species biofilms using a tubular biofilm reactor (TBR). Streptomyces griseus biofilm development was found to be cyclical, starting with the initial adhesion and subsequent development of a visible biofilm after 24 h growth, followed by the complete detachment of the biofilm as a single mass, and ending with the re-colonisation of the tube. Fluorescence microscopy revealed that the filamentous structure of the biofilm was lost upon treatment with protease, but not DNase or metaperiodate, indicating that the extracellular polymeric substance is predominantly protein. When the biofilm was cultivated in conjunction with Bacillus amyloliquefaciens, no detachment was observed after 96 h, although

once subjected to flow detachment. Electron microscopy confirmed the presence of both bacteria in the biofilm and revealed a network of fimbriae-like structures that were much less apparent in single-species biofilm and are likely to increase mechanical Palbociclib order stability when developing in a TBR. This study presents the very first attempt in engineering S. griseus biofilms for continuous bioprocess applications. “
“The diversity of a collection of 49

Lactococcus garvieae strains, including isolates of dairy, fish, meat, vegetable and cereal origin, was explored using a molecular polyphasic approach comprising PCR-ribotyping, REP and RAPD-PCR analyses and a multilocus restriction typing (MLRT) carried out on six partial genes (atpA, tuf, Florfenicol dltA, als, gapC, and galP). This approach allowed high-resolution cluster analysis in which two major groups were distinguishable: one group included dairy isolates, the other group meat isolates. Unexpectedly, of the 12 strains coming from fish, four grouped with dairy isolates, whereas the others with meat isolates. Likewise, strains isolated from vegetables allocated between the two main groups. These findings revealed high variability within the species at both gene and genome levels. The observed genetic heterogeneity among L. garvieae strains was not entirely coherent with the ecological niche of origin of the strains, but rather supports the idea of an early separation of L. garvieae population into two independent genomic lineages. In the last two decades, foodborne diseases have been emerging as an important and growing public health concern.

He referred malaise

and fever since departure, and presumptive diagnosis of spotted fever rickettsiosis was done at admittance and blood aliquot was collected. The serum sample of the patient was analyzed using indirect immunofluorescence with antigens obtained from Vero cell-infected R rickettsii (Sheila Smith Strain). The antigens were prepared at the Adolfo Lutz Institute, São Paulo, Brazil. The IgM antibody titer ≥ 1:64 selleck chemical was considered positive. For culture, blood clot aliquot was centrifuged and the supernatant was inoculated in a confluent monolayer of Vero cells on circular slides adapted to the flat-bottomed tubes (shell vials). Infection of Vero PI3K inhibitor cells was monitored by immunofluorescence

reaction prepared with R rickettsii-positive human serum, which permitted us to observe the presence of fluorescent microorganisms in the form of intracellular bacteria, and SFG rickettsiae were isolated. For molecular characterization of the agent, DNA was extracted from the patient’s blood clot using QIAamp® DNA Blood (QIAGEN, Hilden, Germany), following the manufacturer’s protocol. Rickettsial DNA was detected by polymerase chain reaction (PCR) using the previously described conditions[6] and three sets of primers: CS-78 and CS-32, CS-239 and CS-1069, and Rr190.70p and Rr190.602n.[6, 7] The fragments were cloned into InsT/AcloneTM (Fermentas, Vilnius, Lithuania) and were sequenced in both forward and reverse directions using ABI Prism dGTP BigDye Terminator Ready Reaction Kit (Perkin Elmer, Foster City, CA, USA). The partial sequences of rickettsial ompA and gltA genes were compared with corresponding sequences available in the GenBank (Figure 1). The sequences were aligned with the Clustal W software (1.60). To obtain a better alignment, both pairwise and multiple alignments parameters

were changed from the default set. We used the DNA substitution matrix from the Clustal program, decreased the open gap penalty to 10, and also decreased the transition/transversion Florfenicol rate to 0.25. The alignments were used to construct similarity trees of nucleotide distances estimated by the Neighbor Joining algorithm and number of differences using the MEGA software (Molecular Evolutionary Genetics Analysis, version 3.01). The PCR performed on DNA extracted from the patient blood sample yielded fragments with the expected lengths of gltA and ompA rickettsial genes. Partial sequence of gltA gene was 1,083 bp (GenBank access EU716648), and the nucleotide sequence of ompA gene fragment was 479 bp (GenBank access EU716649). The nucleotide sequences of ompA and gltA genes of our sample (R conorii ICB 1004) had more than 99% identity to the homologous sequences of three R conorii complex strains available in the GenBank.
