| Popis: | Escherichia coli (E.coli) is a normal intestinal microflora of birds, including ostrich. However, some strains are pathogenic to ostrich. There is a lack of knowledge concerning the differences between commensal and pathogenic E.coli isolates of ostrich. This research aimed to characterize the antimicrobial susceptibility profile and virulence gene content of presumptive commensal and pathogenic E.coli isolates of ostrich. A total of 129 bacterial isolates (commensal strains no. = 45; pathogenic strains no. = 84) were obtained from ostriches. The resistance profile of these isolates was investigated by the disk diffusion method and PCR. Also, the strains were screened for virulence-associated genes of avian pathogenic E.coli (APEC). The study showed that the highest and the lowest antimicrobial resistance were against oxytetracycline and gentamicin, respectively. Oxytetracycline, florfenicol, and streptomycin resistance rate in pathogenic isolates were higher than commensal ones (p |
