İnvestigation of several virulance features and resistance against antibiotics of Pseudomonas aeruginosa isolated from environmental resource

ln this study, taken from different regions near Kırşehir soil, water and sludge obtained from 100 samples Pseudomonas aeruginosa strains were used. A total of 12 strains of Pseudomonas aeruginosa rhamnolipids, biofilm, protease, with hemolytic activities were aimed to investigate their sensitivity to antibiotics. As a result all of the strains showed beta-hemolytic activity. Protease activity, rhamnolipid and biofilm forming ability to create differences between isolates showed. Although all isolates were resistant to nalidixic acid, ceftazidime, ceftızoxime, cefotaxime and ceftriaxone 100% (12/12), the P. aeruginosa isolates were susceptible to one or more antibiotics. Key Words: Pseudomonas aeruginosa, virulence factors.
