Bacteriological profile and antimicrobial susceptibility patterns of organisms responsible for blood stream infections
Journal Title: Indian Journal of Microbiology Research - Year 2016, Vol 3, Issue 2
Abstract
Background: Blood stream infections (BSI) are an important cause of morbidity and mortality. An assessment of a patient with BSI includes routinely a blood culture. Blood cultures provide us information on the causative organism and their antibiotic susceptibility over the past few decades. Objective: To identify organisms responsible for Blood stream infections, study their bacteriological profile and antimicrobial susceptibility patterns. Methods: This study was undertaken to analyze all blood culture reports from January 2015-July 2015 at a tertiary care hospital in Hyderabad, India. A total of 485 blood culture reports were analyzed all suspected cases of septicemia. Results: Best sensitivity of the gram positive isolates were for vancomycin and Tigecycline, both giving 97.67% sensitivity followed by Linezolid at 91.86%.The isolates showed good sensitivity of 77.91% to Teicoplanin and Beta-Lactamase combination showing a sensitivity of 72.09% to cefoperazone sulbactam, 66.28% to Ampicillin-sulbactam and 73.26% to cefepime-tazobactum. Resistance was high to other Beta-lactam antibiotics and the Macrolides. Conclusion: The study showed a predominance of gram positive organisms as compared to gram negative isolates, most of the isolates were resistant to multiple antibiotics.
