Abstract
Purpose: Blood stream infections (BSIs) are an importantcause of morbidity and mortality worldwide. Continuous orintermittent presence of microorganisms in the circulating bloodis a danger to every organ in the body. BSIs range from selflimiting infections to life threatening sepsis requiring rapid andaggressive antimicrobial treatment.[1] Culture of blood is a vitaltool to diagnose such infections. Antibiotic susceptibilitypatterns help in rationalizing therapy.Objective: The objective of this study was to determine thebacteriological profile and their antibiotic sensitivity patterns ofisolates from blood stream infections.Materials and Methods: This is a retrospective studyconducted from February 2018 to January 2019 at a tertiarycare hospital, RIMS, India. Blood samples were asepticallycollected and incubated in BD Bactec system, a fullyautomated blood culture system for detection of aerobic growthand incubated for 7 days at 37°C. Identification of microbialgrowth was done by standard methods (biochemical tests) andantibiotic sensitivity test was carried out by Kirby-Baur discdiffusion method as per Clinical Laboratory Standards Instituteguidelines (CLSI guidelines).Results: A total of 82 (28%) pathogens were isolated from 289bacteremia suspect patient blood specimens. Gram‑positivecocci (65.85%) were predominant organisms recoveredfollowed by Gram‑negative bacilli (34.15%). Staphylococcusaureus, Klebsiella spp and CoNS, were the primary pathogensisolated. Staphylococcus aureus (48%) was the predominantamong all. Glycopeptides, aminoglycosides, and carbapenems,were the most effective drugs for treating bacteremia.Conclusions: Early diagnosis and appropriate antimicrobialtreatment is the basis for the successful treatment of sepsis.The understanding of local bacteriological profile andantimicrobial susceptibility patterns may help the clinician inrationalizing the empirical treatment strategies.
