ACINETOBACTER BAUMANNII RESISTANT TO ANTIMICROBIAL DRUGS FROM AN UNIVERSITY HOSPITAL AT CUIABÁ – MT

Abstract

Acinetobacter baumanii has recently taken special notice, and numerous are the reports of infection breakouts in hospital environments worldwide. The extensive use of antibacterial drugs in hospitals has contributed to the increase of muti-resistant strains of A. baumanii, including resistance to carbapenems, which makes the bacteria more difficult to eliminate. This study intends to analyze the susceptibility profiles of different strains of A. baumanii isolated
from clinical samples of patients in treatment in Hospital Universitário de Cuiabá – MT. It consists of a retrospective descriptive study. The bacteria were isolated in appropriate culture media. The identification and antimicrobial susceptibility testing were performed by biochemical tests and Kirby Bauer qualitative method, and Etest quantitative one. From 184 tested samples, 85.3% showed multidrug resistance, especially to cephalosporins (3rd and 4th generation), aminoglycosides and carbapenems. However, 100% of the strains were susceptible to polymyxin B. It was observed that the intensive care unit was the most affected by A. baumannii, and tracheal aspirate was the most prevalent site
of infection by this pathogen.
