Abstract

A total of 200 random samples of imported fish represented by Bangasius hypophanmus (Basa), Mullus surmuletus (Barboni), Saurida undosquamis (Mackerel) and Sparus aurata (Denise) (50 of each) were collected from different markets at Alexandria province during the period extended from March 2014 to February 2015, for detection of some enteropathogens including; enteropathogenic E. coli, Salmonellae, Shigella, Yersinia, Vibrio and Aeromonas hydrophila. It was found that E. coli was detected at an incidence of 42, 36, 38 and 26% in the examined samples of Basa, Barboni, Mackerel and Denis, respectively. Salmonella was isolated at an incidence of 6, 10, 8 and 4% of the examined samples, respectively. Shigella was recovered at an incidence of 26, 22, 28 and 18 % of the examined samples, respectively. Yersinia was detected at an incidence of 46, 42, 36 and 32% of the examined samples, respectively. Vibrio was detected at an incidence of 30, 28, 26 and 22% of the examined samples, respectively. Finally, A. hydrophila incidence was 16, 22, 16 and 12% of the examined samples, respectively. Moreover, biochemical and serological identification of the obtained isolates were performed. Also, the public health significance as well as suggestive hygienic measures to improve the quality of imported fish were discussed.

Key words: Enteropathogens, Basa, Barboni, Mackerel, Denise,
