BACKGROUND This study was aimed to determine frequency and antimicrobial susceptibility of Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) among colonized patients in outpatient status. MATERIALS AND METHODS A total of 2000 nasal nares specimens were collected and inoculated on mannitol salt agar. MRSAs were identified based on mannitol positivity and coagulase test f...

background and objective: staphylococcus aureus is an important infection in hemodialysis patients. we studied the prevalence of nasal carriage of methicillin-resistant staphylococcus aureus (mrsa) and its antibiotic resistance pattern in patients receiving hemodialysis as well as in dialysis unit staff. materials and methods: from june to september 2012, we evaluated 74 cases including 61 pati...

Erythromycin and clindamycin are major alternatives to βlactam antibiotics. Bacterial resistance to macrolide and lincosamide antibiotics is increasing worldwide. Erm genes express either constitutive macrolide, lincosamide streptogramin B resistance phenotype (cMLSB) or inducible phenotype (iMLSB) and msrA gene expresses (MSB) phenotype. The aim of this study was to determine the frequency of ...

The widespread use of Macrolide Lincosamide Streptogramin B (MLSB) antibiotics has led to an increase in the resistant strains. Although Clindamycin is effective against MRSA but its use in the presence of Erythromycin can lead to induction of cross-resistance among members of the MLSB group which could limit the effectiveness of this drug. Furthermore, at times, some strains are also harbored ...
