Abstract

The aim of the study was to assess the prevalence and antibiotic susceptibility profiles of strictly anaerobic Gram-negative bacteria isolated from clinical samples taken from hospitalized patients from 01.01.2007 to 31.12.2008. The specimens were cultured using media, incubated at 37 degrees C under anaerobic conditions. Biochemical identification and antibiotic susceptibility were done in an automated system ATB Expression (bioMerieux S.A, France). For selected strains of Bacteroides sp. sensitivity was determined using E-test (AB BIODISK, Sweden). Overall 1274 strains of obligate anaerobes were isolated. Gram-negative bacteria were cultured in number of 333 strains. Most frequently isolated was Bacteroides sp. (46,9%) and Prevotella sp. (29,7%). Isolated bacteria are still susceptible to imipenem (100%), metronidazole (100%) and beta-lactam antibiotics with beta-lactamase inhibitors: amoxicillin/clavulanate (97,8%) piperacillin/tazobactam (99,1%), ticarcillin/clavulanate (99,1%).
