Bloodstream infection associated bacterial pathogens and antibiotic resistance - ICU based pilot study
Journal Title: Medpulse International Journal of Microbiology - Year 2017, Vol 3, Issue 2
Abstract
Background: ICU is common place of multi-drug resistant micro-organisms. The microbiological detection of bacteraemia is important for prompt management but culture and antibiotic susceptibility tests results take 3-4 days. Thus providing updated knowledge to intesivists about antibiotic susceptibility pattern is important in initiation of empiric therapy. Methodology: The present study was undertaken to know the microbiological profile of BSI in patients from medical and surgical ICU. Isolates were studied for their microbial characterization, antibiotic susceptibility pattern and specific antibiotic resistance mechanism. Results: From 150 suspected cases, 22%developed BSI. Commonest isolates were P. aeruginosa and A. Baumannii which showed ESBL and MBL production as predominant mechanism of resistance. Conclusion: The high prevalence of antimicrobial resistance in isolates causing BSI in ICUs warrants implementation of strict antibiotic policy and adherence to hospital infection control measures.
