ABSTRACT
ABSTRACT Enterobacter cloacae and E. aerogenes have been increasingly reported as important opportunistic pathogens. In this study, a high prevalence of multi-drug resistant isolates from Brazil, harboring several β-lactamase encoding genes was found. Several virulence genes were observed in E. aerogenes, contrasting with the E. cloacae isolates which presented none.

400 strains of Klebsiellae identified by culture characteristics and biochemical reactions were subjected to biotyping, antibiogram and klebocin typing. Based on indole production, pectin and gelatin liquefaction 16.0% of all the isolates were Klebsiella oxytoca. Maximum sensitivity was shown to Amikacin (72%) and maximum resistance to Ampicillin (87.5%). Klebocin typability was 73.5%. So by combining biotyping, antibiogram and Klebocin typing, Klebsiella could be differentiated better than based on any single marker.
