tailieunhanh - Phenotypic detection of MRSA and inducible clindamycin resistance among clinical isolates of Staphylococcus-study done in a Tertiary level Hospital

Staphylococcus aureus is a versatile human pathogen causing infections ranging from relatively mild skin and soft tissue infection to life threatening sepsis, pneumonia and toxic shock syndrome. The increasing incidence of a variety of infections and, especially, the expanding role of community-associated methicillin-resistant S. aureus (MRSA)--has led to emphasis on the need for safe and effective agents to treat both systemic and localized staphylococcal infections. Clindamycin is considered to be one of the alternative agents in these infections. The present study was aimed to detect prevalence of inducible clindamycin resistance among S. aureus isolates and to study the relationship between clindamycin and methicillin resistance and correlation with multidrug resistance. During a period of6 months, a total of 245 Staphylococcal isolates from various clinical specimens were included in the study. Antimicrobial susceptibility test was done by Kirby-Bauer’s disc diffusion method, MRSA detection was done by using Cefoxitin discs. For detection of inducible clindamycin resistance, D test was done by double disc synergy (DDS) test using erythromycin and clindamycin antibiotic discs and three different phenotypes were interpreted as methicillin-sensitive (MS) phenotype (D test negative), inducible MLSB (iMLSB) phenotype (D test positive), and constitutive MLSB phenotype. In study time of 6 months 245 non repeated isolates of Staphylococci were detected from various clinical samples like blood, urine, pus, vaginal swab and other samples,157 were from Paediatrics and 33 from gynae. | Phenotypic detection of MRSA and inducible clindamycin resistance among clinical isolates of Staphylococcus-study done in a Tertiary level Hospital
