Abstract

Introduction & Objectives: Blood stream infections are the most important and common cause of morbidity and mortality in tertiary care hospitals. Since the results are usually not available promptly a knowledge of epidemiologic and antimicrobial susceptibility pattern of blood pathogens is life saving and very useful for early treatment and recovery of patients. The aim of this study is to describe the epidemiological, bacterial profile and antimicrobial resistance pattern of bloodstream infections in a tertiary
care centre.
Materials and Methods: A prospective cross-sectional study was done on seven hundred and eight blood samples collected over a period of six months in the Microbiology laboratory. Blood samples collected under aseptic conditions were cultured by aerobic culture method. Identification of bacterial isolates were done using standard bacteriologic and biochemical testing methods and antibiotic sensitivity testing done by Kirby - Bauer disc diffusion method.
Result: Bacteria was isolated in 201 (28.3%) samples with highest rates among newborns 84(41.8%). The most frequent isolates were Coagulase negative staphylococci 111 (55.2%) followed by Klebsiella pneumoniae 49 (24.4%). Results showed high susceptibilities of CoNS 111 (100%) to Vancomycin, Linezolid and Klebsiella 51 (98%) to Meropenem. This study highlights the common prevalent bacteriological agents in bacteremia, their antibiotic susceptibility & resistance patterns.
Conclusion: Coagulase negative staphylococci and multi drug resistant Klebsiella were the leading causes of septicaemia in our hospital with Vancomycin, Linezolid and Carbapenems the effective antibiotics against these pathogens respectively.
