conclusions the rate of imlsb in s. aureus isolates is relatively high in the northwest iran. since isolates with inducible resistance may mutate and change to constitutive resistance, to prevent clinical treatment failure, d-test should be performed along with routine antibiotic susceptibility tests. in this study, ermc gene was the predominant genetic determinant for the expression of mlsb re...

background: staphylococcus aureus (s. aureus) is a major nosocomial pathogen and the infection with this organism in human is increasing due to the spread of antibiotic resistant strains. one of the resistance mechanisms of s. aureus comprises modification in binding proteins to penicillin. vaccine strategy may be useful in controlling the infections induced by this organism. this study aimed a...

conclusions thirty-three bacterial strains; 10 strains of e. coli, 10 strains of s. flexneri, 3 strains s. sonnei, 2 strains of s. serovar newport, and 7 strains of p. aeruginosa, were isolated and identified from nile water and ground water in sohag governorate. the prevalence of enteric bacteria in water sources in studying area was considerable. no clear or distinct correlation could be conc...

b a ckground: s taphylococcus aureus (s. aureus) has remained always an important pathogen of common infections acquired in community and as  well as serious nosocomial infections. with advent of penicillins and cephalosporins, infections could be effectively treated, but with the global emergence of methicillin resistant staphylococcus aureus strains (mrsa) physicians were  again left  with li...

Statphylococcus aureus is a Gram positive bacterium, which is naturally present in nasopharyngeal region of human beings and animals. After 1941, S.aureus was developed drug resistant capacity to against all penicillin antibiotics. In 1961, Methicillin Resistant Staphylococcus aureus were isolated. The present study Methicillin Resistant S. aureus were isolated from clinical pus samples. All is...

We studied the transmissibility of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) and healthcare-associated methicillin-resistant S. aureus (HA-MRSA) strains and the association of MRSA colonization pressure and MRSA transmission in critically ill children. Importantly, we found that in hospitalized children MRSA colonization pressure above 10% increases the risk of ...

background and objectives: staphylococcus aureus is an important cause of nosocomial and community-acquired infections in every region of the world. clindamycin is one of the alternative agents used to treat s. aureus infections and accurate identification of clindamycin resistance is important to prevent therapeutic failure. unfortunately, inducible clindamycin resistance is not detected by st...

Ten samples containing various amounts of methicillin-resistant Staphylococcus aureus (MRSA), methicillin-susceptible S. aureus, methicillin-resistant Staphylococcus epidermidis (MRSE), and combinations thereof were distributed to 51 laboratories for molecular diagnostics testing. Samples containing 10(2) to 10(3) MRSA cells were frequently reported to be negative. MRSE samples were scored as n...

In 928 Dallas County Jail detainees, nasal carriage of Staphylococcus aureus was found in 32.8% (26.5% methicillin-susceptible Staphylococcus aureus [MSSA] and 6.3% methicillin-resistant S. aureus [MRSA]), and hand carriage was found in 24.9% (20.7% MSSA and 4.1% MRSA). Among MRSA nasal carriers, 41% had hand MRSA carriage; 29% with hand MRSA carriage had no nasal S. aureus carriage. The preval...
