الملخص EN

This study was carried out during the period from April 2014 to November 2014.

A total of 250 seafood samples, 50 samples each namely Mullet, Sardine, Shrimp, Cuttlefish and Mussel, obtained by random sampling from the coast of Port Said Governorate.

Samples were subjected to conventional method for the detection of Vibrio species.

Overall, 32% of the Mullet, 36% of Sardine, 52% of Shrimp, 44% of both Cuttlefish and Mussel samples were found to be positive for Vibrio spp.

The prevalence of Vibrio species was higher in shellfish samples, particularly in shrimp than that of fish samples.

Four Vibrio species were identified.

V.

alginolyticus was found to be the dominant identified Vibrio species with total prevalence of 48.2% (50/104) followed by V.

damsela 24% (25/104), V.

harveyi 16.3% (17/104) and V.

parahaemolyticus 11.5% (12/104).

Eight isolates identified phenotypically as Vibrio species, were confirmed by PCR.
