Abstract:
Seven hundred and thirty fishes and 276 crustaceans collected from various fish markets of
Coimbatore, South India, over a period of 2 years (September 1990 to August 1992) were
analysed for the prevalence of Salmonella. Fishes (14·25%) and 17·39% of crustaceans were
found to be contaminated with Salmonella. Of the different fishes analysed, the highest
incidence of Salmonella was seen in Scopelidae (28%) followed by Trachnidae (26·9%).
Among crustaceans Portunus pelagicus (33·33%) showed the highest incidence followed by
Scylla serrata (28·57%). A well-marked seasonal variation in the incidence pattern was
observed in both fishes and crustaceans with a higher incidence during monsoon season
followed by post-monsoon and pre-monsoon. The region of the body that showed frequent
isolation was the alimentary canal in fishes (41·33%) and gills (35·06%) in crustaceans.
Serotyping of the isolates revealed prevalence of Salmonella weltevreden, Salmonella
typhi, Salmonella paratyphi B, Salmonella mgulani and Salmonella typhimurium in both
fishes and crustaceans. Salmonella senftenberg was isolated only from crustaceans
