Abstract
Background: Cytolethal distending toxin (CDT) gene is one of the important virulence factors in Escherichia coliisolated from different human and animal sources strains. Objectives: The aim of this study was to investigate the frequency of CDT genes in E. coliisolates from bovine mastitis in Tabriz City (East Azarbaijan province) in 2020. Methods: In this cross-sectional descriptive study, after isolation and biochemical and molecular identification of 100 E. colifrom bovine mastitis, the frequency of cdt-I, cdt-III, and cdt-IVgenes was assessed by PCR method. Results: Of a total of 100 tested E. colisamples, 94 isolates were confirmed as E. coliby PCR test. Of the 96 E. coliisolates, none had the cdt-I, cdt-III, and cdt-IVgenes. Conclusions: The results of this study showed that the frequency of the cdtgene in E. coliisolates from cow mastitis is very low, like the other animal sources in past studies.
