    Occurrence of enterotoxigenic staphylococci in frozen fishery products
    (Society of Fisheries Technologis(India), 1986) Sanjeev, S.; Mahadeva Iyer, K.; Rao, C.C.P.; Arul James, M.
    Sixty six samples of frozen fishery products consisting of frozen crab meat, frozen prawns, frozen cuttle fish and frozen mussel collected from nine cold stores situated in and around Cochin city were examined for coagulase positive staphylococci. Forty eight samples (72.72%) revealed the presence of coagulase positive staphylococci, which were then tested for enterotoxigenity, employing cellophane-over-agar method forĀ· toxin production and optimum-sensitivity-plate (OSP) method for toxin detection. Seventy seven out of one hundred and two (75.49%) coagulase positive staphylococcal isolates from the above products produced enterotoxins A, B, C, D and E either singly or in combinations. Enterotoxin A and D were detected more often than others. The occurrence of enterotoxigenic staphylococci in frozen fishery product is reported for the first time in this country.

    Studies on isolation of Salmonella from seafoods - I. Comparison of enrishment and selective media for recovery of salmonella from fish
    (Society of Fisheries Technologis(India), 1972) Arul James, M.; MahadevaIyer, K.
    Three enrichment broths and six plating media were compared for efficiency of detection of Salmonella in the presence of high numbers of Conforms (105/ml) and proteus (103/m1) from artificially inoculated fish samples. Recovery experiments with Salmonellaanatum S. typhimurium and S. enteritidis indicated that the two enrichment broths viz. Dulcitol Selinite (DSE) and Selinite Cystine (SC) were equally efficient. Further, the viability of Salmonella, inoculated into fish muscle and kept at 40 C for 48 hours, was found to be not affected by the low temperature storage. Selective plating media like Xylose Lysine Deoxycholate agar (XLD), Brilliant Green Sulphadiazine agar (BGS) and Brilliant Green agar (BG) were found to be superior in performance to Salmonella-Shigella agar: (SS) and Bismuth Sul phite agar (BiS).
