Background. Current susceptibility testing recommendations for β-hemolytic streptococci outline testing for clindamycin resistance, including inducible resistance by a positive D-zone phenotype. However, few studies describe the prevalence of clindamycin resistance among invasive GCS and GGS organisms. This study aims to describe the prevalence of clindamycin resistance among GCS/GGS compared w...

Staphylococci are important causative agents of nosocomial and community acquired infections in skin and soft tissues. Emergence of methicillin resistance in Staphylococci has left us with very few therapeutic alternatives available to treat. The Macrolide – lincosamide Streptogramin B (MLSB) family of antibiotics serves as one such alternative with Clindamycin being preferred agent due to its ...

The emergence of resistance to most antimicrobial agents in staphylococci indicates the need for new effective agents in the treatment of staphylococcal infections. Clindamycin is considered to be one safe, effective and less costly agent. We analysed 482 staphylococcal isolates. Detection of inducible clindamycin resistance was performed by the D-test, while the presence of methylases genes: e...

D test is a simple disc diffusion test giving high throughput results. It is used to study the macrolide lincosamide streptogramin resistance (MLSB), both constitutive and inducible as well as macrolide streptogramin resistance (MSB) in Staphylococcus aureus. In this test, erythromycin (macrolide) and clindamycin (lincosamide derivative) discs are placed adjacent to each other over the Mueller ...

A total of 212 clinical Streptococcus pyogenes isolates were tested for susceptibility to various antibiotics by agar dilution. The overall frequency of erythromycin resistance was 12.7%, being higher in isolates from children (18.9%) than in those from adult patients (10.7%). Similar results were found for clarithromycin, while 2.8% of the isolates were resistant to ciprofloxacin. All strains ...
