Enterobacteriaceae in locally produced fishes

ABSTRACT

Hundred fish samples each of Tilapia nilotica, clarias pagrus and solea species; were collected from fish markets, at Cairo, 25 sample from each species were collected during each season of the year. Samples were subjected to bacteriological examinations for the determination of the total enterobacteriaceae counts per cm[2] surface and per gram muscles and for the isolation and identification of enterobacteriaceae. Obtained counts and identified enterobacteriaceae organisms were recorded. In conclusion, the counts of enterobacteriaceae were higher in fresh water fish than in marine fish and also during summer than other seasons of the year. This could be attributed to the effect of temperature on the bacterial growth. The public health significance of the isolated enterobacteriaceae organisms was discussed in details
