Abstract

A grand total of 100 random samples of fresh water fish with average weight 100-250g
(Oreochromis niloticus), marine water fish (Mugil cephalus), and shell fish (shrimp and crab) with
average weight 10-50g were collected from different markets in Gharbia governorate for detection
of Vibrio spp. The obtained results revealed that the incidence of Vibrio spp. in fresh water fish
(Oreochromis niloticus) were 8 (32%), with frequency of 2 (8%), 2 (8%), 2 (8%), 1 (4%) and 1 (4%)
for V. parahaemolyticus, V. mimicus, V. vulnificus, V. alginolyticus and V. fluvialis, respectively. In
marine fish (Mugil cephalus),Vibrio spp. were 10 (40%), the overall incidence in the samples was
for V. parahaemolyticus 3(12%), V. mimicus 2(8%), V. alginolyticus 2 (8%), V. vulnificus 1 (4%)
and V. fluvialis 2 (8%). In shell fish (shrimp), Vibrio spp. were 13 (52%) while the overall incidence
in the samples was V. parahaemolyticus 4 (16%), mimicus 3 (12%), V. alginolyticus 2 (8%), V.
vulnificus 1 (4%), V. fluvialis 2 (8%) and V. cholera 1 (4%). Regarding crab, Vibrio spp. were 11
(44%) while the overall incidence in the samples was V. parahaemolyticus 3 (12%), mimicus 2 (8%),
V. alginolyticus 2 (8%), V. vulnificus 1 (4%), V. fluvialis 2 (8%) and V. cholera 1 (4%).
