Phylogenetic relationship and virulence gene profiles of avian pathogenic and uropathogenic Escherichia coli isolated from avian colibacillosis and human urinary tract infections (UTIs).

BACKGROUND: (ExPEC) strains such as human uropathogenic isolates. AIMS ‏‏: The present study was conducted to evaluate virulence and phylogenetic relationship between a total of 70 APEC and UPEC isolates (35 APEC and 35 UPEC isolates) obtained from the north of Iran which is one of the core areas of the country's poultry industry. METHODS: Polymerase chain reaction (PCR) and random amplified polymorphism DNA (RAPD) analyses were conducted using specific primers, and data was analyzed using BioNumerics and SPSS softwares. RESULTS: and predominant phylogenetic groups in DNA fingerprinting methods. CONCLUSION: , APEC isolates can have a high potential for causing disease in humans and may generate dangerous outbreaks in communities with low levels of hygiene in public and the poultry industry.
