Prevalence and Identification of Streptococci and Enterococci from Various Clinical Specimens in a Tertiary Care Centre
Journal Title: Journal of Medical Science And clinical Research - Year 2016, Vol 4, Issue 12
Abstract
Aim: To study the distribution of Streptococci and Enterococci in various clinical specimens. Materials and Methods: Streptococci and Enterococci isolated from various clinical specimens in Central Microbiology Laboratory, Government Medical College, Thiruvananthapuram over a period of one year from January 2014 to December 2014 were included in the study. The specimens were cultured using aerobic and anaerobic microbiological techniques. Streptococci and Enterococci were identified by standard laboratory procedures as per CLSI guidelines. Antimicrobial susceptibility testing was carried out using disc diffusion method. Grouping was done by latex agglutination. Results: Majority of group A Streptococci (GAS-82.95%), group B Streptococci(GBS-72.60%),group F Streptococci (GFS-63.63%) and group G Streptococci (GGS-50%) were obtained from pus .Group C Streptococci(GCS-58.33%) was obtained from sputum. Maximum number of Enterococci was obtained from urine(45.37%).Majority of the isolates of GAS(52.27%),GBS(49.31%),GCS(41.66%)and GGS(50%) were from skin and soft tissue infections while GFS(36.36%) was from dentoalveolar abscess. Theenterococcal isolates were mainly from urinary tract infections(44.44%).All the Streptococcal isolates were sensitive to Penicillin. Only 96.29% of Enterococci were sensitive to Vancomycin. Conclusion: Most of the Streptocccal infections are life threatening. Hence it is necessary to develop preventive, diagnostic and therapeutic strategies against them.Due to the emergence of Vancomycin resistant Enterococci, it is recommended to perform screening test and MIC determination to confirm resistance of local strains to this antibiotic
