Isolation and Identification of Fecal Escherichia coli from Stray Dog at Chittagong Metropolitan Area

Abstract

Escherichia coli infection is one of the most usual and extensively dispersed comprehensive public health concerns. A cross sectional study was directed to investigate the prevalence of Escherichia coli (E. coli) isolated from rectal swab of stray dogs in the randomly selected 12 areas of Chittagong City Corporation to assess the risk of possible transmission of E. coli from dog to human. Samples were collected during the period of February to May, 2015. Bacteriological isolation methods were done to detect E. coli for evaluating the public health crises. Out of the 83 samples the highest prevalence of E. coli was found (100%) in Pahartolli, Sholosahar, Alankar, Chawkbazar area and lowest prevalence in Bahaddarhat (0%) area. Therefore, it can be said that appropriate measures should be taken to prevent occurrence of zoonotic E. coli infection in human.
