background staphylococcus aureus is a significant pathogen that can colonize the nares of different animals, causing a wide range of infections in various hosts. objectives we intended to determine the prevalence of s. aureus in the nasal cavity of healthy ruminants and also to investigate the presence of antibiotic resistance genes. materials and methods in the present study, healthy cattle (n...

conclusions our results illustrated the presence of clonal groups of highly gentamicin-resistant strains of mrsa in hospitals in tehran. the php typing method provided useful information for both clonal dissemination and determining the epidemiological links of the clonal groups of the mrsa strains. materials and methods a total of 301 s. aureus isolates were collected during january to novembe...

conclusions the results revealed, the specific primers that amplified the ente gene were able to amplify the staphylococcal enterotoxin-like toxin type p gene. the specific primers for the entp gene were amplified a fragmented gene (700 bp) showed 100% homology with entp reference gene and also 80% homology with enta and ente genes. results the pcr amplification method was optimized for entp ge...

background hospital patients who are nasal carriers of methicillin-resistant staphylococcus aureus (mrsa) are a high-risk potential threat to themselves and other hospitalized patients. the high antibiotic resistance of these isolates renders the treatment of related infections difficult. objectives the present study, for the first time investigated the prevalence of mrsa isolates in nasal carr...

objective(s)staphylococcus aureus is a prevalent pathogen worldwide. methicillin resistant s. aureus (mrsa), which is usually multi-resistant in hospitals, has been a daunting challenge for clinicians for more than half a century. the aim of this systematic review and meta-analysis is to determine the relative frequency (rf) of mrsa in different regions of iran.materials and methodssearch terms...

objective(s) methicillin-resistant staphylococcus aureus (mrsa) is an important cause of nosocomial and community infections. biofilm formation, mediated by a polysaccharide intercellular adhesin (pia) and encoded by the ica operon, is considered to be an important virulence factor in both s. epidermidis and s. aureus. however, the clinical impact of the ica locus and pia production is less wel...

background: this study was undertaken to evaluate staphylococcus aureus carriage and persistence in health sciences students at the faculty of medicine and health sciences, universiti putra malaysia. methods: consent form and self-administered questionnaires on socio-demographics, hygienic practices, medical and medication history were distributed followed by nasal swab collection; sampling was...

background and objective : the prevalence of community acquired methicillin resistant staphylococcus aureus (ca-mrsa) is increasing around the world. it involves healthy people and causes a variety of diseases. material and methods : this cross sectional study was conducted from september 2010 - june 2011 on children less than 14 years of ahvaz, southwest iran. the participants were selected wi...

staphylococcus aureus produces a particular morphological variant called small colony variant (scv) which is responsible for persistent subclinical infections in predisposed individuals and is usually resistant to aminoglycosides and cell wall active antibiotics. infections by scv of s. aureus are an upcoming problem due to difficulty in laboratory diagnosis and resistance to antimicrobial chem...

background staphylococcus aureus (s. aureus) is the most common pathogen responsible for osteomyelitis. conclusions parenteral administration of viable l. casei inhibits s. aureus-induced infection as shown by the bacteriologic analysis, but makes no difference to the radiological :union: rates. this could be the first step towards developing an effective, biologic adjunctive therapy for the ma...
