Bacteriological study of non-fermenters and their antibiogram in tertiary care hospital

Abstract

Non –fermenting Gram-negative bacilli are a group of heterogeneous, aerobic, nonsporing bacteria. They are saprophytes in nature and are also found as commensals in man and other animals. This study aims to isolate and identification of NFGNB from various clinical specimens and to find out their clinical significance among the in-patients admitted at Vijayanagar Institute of Medical Sciences, Bellary. 110 isolates from various age groups and sexes were included in the study. A detailed history was elicited and the clinical specimens were collected under aseptic precaution and subjected to preliminary biochemical tests and further speciation was done. In the present study commonest isolates were Pseudomonas aeruginosa, Acinetobacter baumannii, Acinetobacter haemolyticus, Pseudomonas fluorescence, Acinetobacter lwoffi Acinetobacter junii, Acinetobacter radioresistant and from urinary tract infection which accounted for (34.5%), followed by respiratory tract infection (21.2%), local infection (20.9%), Post operative infection (8.18%), infection related to the abdomen (6.36%), Septicemia (5.45%), and post-traumatic infection (2.7%) in decreasing order of frequency. They showed variability in their antibiotic susceptibility results, Most of them were sensitive to Carbapenem groups of drugs.
