Anaerobic bacteria are predominant residents of the normal microbiota of the skin and mucous membranes but are also known to be associated with a number of human infections including peritonitis, appendicitis, abscesses, ulcers and wound infections. Herein, we investigate the antibiotic resistance profiles as well as the genetic support of antibiotic resistance and virulence determinants of anaerobic bacteria isolated from intra-abdominal infections. The study was performed on 198 Romanian patients from which different clinical samples were taken intra-operatory and sent for microbiological analyses. From the total number of isolated strains, a subset of 75 Bacteroides spp. were selected and further investigated for antibiotic resistance and virulence features, at phenotypic and genetic level. Our results obtained through the analysis of a significant number of Bacteroides strains could shed light on the virulence potential and mechanisms by which anaerobic bacteria can cause endogenous infections.
