Abstract
Histidine decarboxylase activity of Enterobacteriaceae isolates from 104 samples of fish and shellfish samples collected from retail markets of Cochin was studied. The total Enterobacteriaceae count varied from 2.5 to 6.5 log cfu g- 1 among the different fish species. Generic level characterization of 248 enteric bacteria showed that Enterobacter Spp., and Escherichia Spp. were the dominant groups. All the isolates were checked for their ability to decarboxylase histidine and the isolates showing positive reaction from different sample sources were reported. Effect of five different incubation temperatures on the decarboxylase activity of these isolates was also evaluated.
