Isolation of microorganism from Blood sample and their antibiotic susceptibility pattern

  • Arun Kumar et al.

Abstract

Bacteriemia is one of the main causes of mortality and morbidity. In the present work,
concurrent surveillance for blood stream infection has been performed at SRL Diagnostics
Centre, Gurgaon over the period of four months. Isolation of microorganism from blood
samples and their antibiotic sensitivity aw sell as resistance pattern against the commonly
used antibiotics were evaluated. A total of 21 types of microbial infections, bacterial and
fungal, were detected during the study. A total of 500 sample were collected and grampositive organisms accounted for 32.95% cases, gram negative organism was accounted for
42.04% cases and fungal infection were detected in 25% cases. The most common
microorganismswereSalmonella typhi (12.50%), Klebsiella pneumoniae (9.09%),
Staphylococcus epidermidis (9.09%), Escherichia coli (6.81%), Streptococcus haemolyticus
(6.81%), Staphylococcus aureus (4.54%), and candida found in the patients. Total 88 sample
(17.6%) were found positive out of total 500 evaluated samples. S. epidermidiswas the most
prevalent isolate among gram positive bacteria, and S. typhi was the most predominant
isolates and among gram negative bacteria. The most sensitive antibiotics against the grampositive isolates was daptomycin and against gram-negative isolates was imipenem.
