A microbiological study of acinetobacter baumannii with special reference to multi-drug resistance

Acinetobacter calcoaceticus baumannii (ACB) is a significant pathogen in hospitals with a growing incidence of multi-drug resistant (MDR) strains. This was a prospective study carried out on ACB isolates from clinical samples between 2013 and 2015. Anti-microbial susceptibility testing was done by Kirby-Bauer Disk Diffusion method (KBBD) method. CRAB strains were tested by Modified Hodge test (MHT) to detect MBL producers. Of the 190 ACB isolates, 142 (75%) were MDR strains. 93% were hospital acquired and 7% community acquired. MDR was seen only in hospital acquired isolates.
