Resumo: | The production of extended-spectrum beta-lactamases (ESBL) is considered one of the most important resistance mechanisms that impair antimicrobial treatment of infections caused by Enterobacteriaceae. Data on culture and susceptibility tests were collected from the Clinical Analyses and Research Laboratory charts reporting on patients admitted to the University Hospital of Maringá (HUM) from January 2004 to December 2009. The following Enterobacteriaceae were selected: Escherichia coli, Klebsiella pneumoniae, Klebsiella oxytoca, Enterobacter spp. and Proteus mirabilis. All tests were performed according to the recommendations of the Clinical and Laboratory Standards Institute (biochemical identification; susceptibility tests; initial screening and phenotypic confirmatory tests for ESBL). For Enterobacter spp. isolates, a disk approximation test was carried out, adding a cefepime disk. Seven hundred samples were analyzed, and E. coli was the most prevalent bacteria (n= 356). ESBLs were detected phenotypically in 7.3% of E. coli, 61.7% of K. pneumoniae, 33.3% of K. oxytoca, 7.1% of P. mirabilis, and 13.4% of Enterobacter spp samples. Overall ESBL prevalence reached 22% when all producers were taken together. Although HUM is considered a small-sized hospital, it showed high levels of resistance to antimicrobial agents, similar to those observed in bigger hospitals, which demonstrated the need for careful epidemiological surveillance.
