Resumo
The work conditions of dental surgeons (DS), associated with low compliance to precautionary
standards, often lead to the colonization and dissemination of infectious agents. To assess
the epidemiological and microbiological aspects of nasal colonization by Gram-negative
bacteria in DS while teaching (dentistry teachers). The data were collected by application of a
questionnaire and a nasal swab. The biochemical identification, the susceptibility profile and
the detection of β-lactamases were carried out in Vitek 2 compact®. 41 (77.3%) DS participated
in the study, nine of them (22.0%) presented nasal colonization by Enterobacteriaceae, the
participants were predominantly men (27/65.9%), over 50 years of age (24/58.5%). All of
them confirmed using procedure gloves and a surgical mask while attending patients, with
frequent (95.5%) hand washing although a statistical difference was found regarding personal
habits (p=0.03). Enterobacter aerogenes (60.0%) was the most prevalent species, followed by
Citrobacter koseri (20.0%). The intrinsic production of AmpC β-lactamase by E. aerogenes
species, which is multiresistant to antimicrobials, was present in the nasal cavity of 14.6% of
the DS. There were high levels of nasal colonization by Enterobacteriaceae in teaching DS
(22.0%), 14.6% had been colonized by multiresistant microorganisms and the results were
associated with inadequate personal habits.
