The aim of this study was to evaluate the prevalence of some virulence genes among 202 Pseudomonas aeruginosa isolates from cystic fibrosis (CF) patients (n=42) and non-CF in-patients (n=160) and to analyze the values according to the patient groups, infection localization and antimicrobial resistance. The following frequencies in all studied strains were(More)
A total of 424 Enterococcus spp. isolates from clinical samples (n = 398) and traditional Bulgarian artisanal cheeses (n = 26) were studied in order to evaluate the incidence and expression of bacteriocin genetic determinants. Structural genes coding for enterocin A (entA), enterocin P (entP), enterocin B (entB), enterocin AS-48 (as-48) and enterolysin A(More)
We report a case of an adult patient undergoing three unsuccessful Helicobacter pylori treatments, including proton pump inhibitor (PPI), bismuth subcitrate, metronidazole and tetracycline in 2012, PPI, amoxicillin and clarithromycin in 2013, and PPI, amoxicillin and rifampin in 2014. Following the first treatment, the isolate was metronidazole and(More)
The aim of the retrospective study was to evaluate geographic regions and residence places as possible risk factors for primary Helicobacter pylori antibiotic resistance in Bulgaria. Data from Sofia region, exhibiting the highest living density, were compared to those from other residence places. In total, 588 H. pylori strains from untreated adults who(More)
