Group B Streptococcus (GBS), a commensal in the body, causes wide range of infectious diseases. This bacterium is dangerous for pregnant women and their babies, whom it responsible early neonatal bacterial sepsis (EOS). The colonisation levels GBS its resistance profile to antibiotics provide important information that useful orienting prevention strategies. There are few data available on subj...
BACKGROUND & OBJECTIVES Methicillin resistant Staphylococcus aureus (MRSA) isolates with inducible clindamycin resistance (iCR) are resistant to erythromycin and sensitive to clindamycin on routine testing and inducible clindamycin resistance can only be identified by D-test. This study was aimed to detect methicillin resistance and iCR among S. aureus isolates, effectiveness of some commonly u...
We describe the development and validation of an agar dilution method for the detection of inducible clindamycin resistance by using 227 previously characterized erythromycin-resistant, clindamycin-susceptible Staphylococcus sp. isolates. Mueller-Hinton agar with defibrinated horse blood containing a range of erythromycin concentrations (1 to 8 mg/liter) combined with clindamycin at 0.5 mg/lite...
This study aimed to determine the levels of the macrolides-lincosamides-streptogramins B (MLS(B)) resistance phenotype of Staphylococcus aureus and coagulase-negative staphylococci (CNS) isolates from clinical samples. A total of 521 strains of staphylococci, comprising 230 S. aureus and 291 CNS isolates from various clinical samples, were identified by conventional methods. The double-disc tes...
Our objective was to characterize 46 unique, erythromycin-sensitive, and clindamycin-resistant Streptococcus agalactiae strains from S. Korea that displayed a novel phenotype in double-disk diffusion assay. We used polymerase chain reaction to determine presence of erythromycin and clindamycin resistance genes, disc diffusion assays to determine resistance phenotype, and microbroth dilution to ...
OBJECTIVES To assess the epidemiology, antibiotic resistance and genotypic characterization of group A streptococci (GAS) in Jinju, Korea. METHODS Isolates were characterized in terms of their antibiotic resistance, the phenotypes of erythromycin resistance, the frequencies of erm(B), erm(A) and mef(A) genes, and by emm genotyping or M typing. The data were compared with those from 85 GAS str...
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...
