Isolation and Identification of Escherichia albertii in Broiler Chickens From Kermanshah

F Escherichia albertii is generally recognized as a human pathogen with a limited number of strains. It has also been identified as a cause of mortality among birds. The clinical significance and prevalence of E. albertii are somewhat unknown.

The aim of the present study was to isolate and identify E. albertii as a causative agent of respiratory infections in broilers.

During a three-month period (Winter 2018), 200 samples of the air sacs of 100 chickens with suspected colibacillosis were collected. Routine biochemical tests were performed and suspected isolates of E. albertii were selected for polymerase chain reaction (PCR).

A total of 68 suspected samples of E. albertii and Escherichia coli were isolated. Further, E. coli was detected in all the suspected samples using species-specific sequences of E. coli (uidA) and E. albertii (mdh and lysP).

Escherichia albertii was not identified as a cause of respiratory infection in broil
