Abstract

The aim of this study was to determine the prevalence of Gram-negative (GNB) isolated from the saliva of health workers in a school hospital in Goiânia-Goiás, and to characterize the profile of the colonized individuals. From August/2005 to July/2006, 278 health care workers participated of the study. The GNB carrier rate was 69.4%, being 44% of them persistent carriers, and 49.2% multicolonized carriers. 319 BGN were isolated, of which 208 (65.2%) were Enterobacteriaceae and 111 (34.8%) non-fermenters. The main species identified were Enterobacter aerogenes (17.9%), Klebsiella pneumoniae (16.3%), and Enterobacter agglomerans (8.8%). In the group of non-fermenting GNB were isolated 25 (7.8%) Pseudomonas aeruginosa. High prevalence of colonization by GNB was observed. The results of this study are of great importance because BGN are important in the etiology and pathogenesis of infections associated with health care of critically ill patients, undergoing invasive procedures and prolonged stay in the nosocomial environment.
