    Bacterial Flora of Fresh and Iced Indian Mackerel (Rastrelliger Kanagurta) and its Response to Chlortetracycline (CTC) Treatment
    (Society of Fisheries Technologists (India), Cochin, 1976) Surendran, P.K.; Iyer, K.M.
    Quantitative and qualitative studies on the bacterial flora of fresh Indian mackerel (Rastrelliger kanagurta) have been made. The total native flora as well as 5 ppm. CTC insensitive flora of the fish showed variations with season. About 90 % of the fresh fish flora was sensitive to 5 ppm . CTC. The natural flora of the fresh fish consisted of Vibrios, Pseudomonas, Achromobacter, Flavobacterium, Corynebacteria,Micrococci, Bacillus and yeasts . In the CTC insensitive flora, Vibrios predominated followed by yeasts . The selection of bacterial genera during storage of the fish in ice and in 5 ppm. CTC incorporated ice has also been investigated . At the time of spoilage, Pseudomonas were found to be the dominant flora of the fish stored in both types of ice .

    Bacterial Flora of some Fishes of Maharashtra and Saurashtra Coasts (India)
    (Springer, 1989) Beri, H.K.; James, M.A.; Solanki, K.K.
    Native microflora in didirrerent varieties of fishes available along Maharashtra and Sourashtra Coasts in India were studies during 1983-1987. The flora of fishes studied were Saurida tumbil, Nemipterus, Lepturocenthus savala, chirocentrus dorah and Coilia dussumeri. The groups of bacteria, belonged to Vibrio, Acinetobacter, pseudomonas, Micrococus, Sarcina, Flavobacterium and Cytophaga species. Sometimes anaerobes were also isolated from the fish intestines.

    Bacterial profile of black clam (Villorita cyprinoides) var. cochinensis and Clam harvesting waters from Vembanad lake in Kerala (India)
    (Society of Fisheries Technologists (India) Cochin, 2005) Lalitha, K.V.; Surendran, P.K.
    The bacterial flora of black clam (Villorita cyprinoides var. cochinensis) and water samples collected from three clam harvesting areas in Vembanad lake (Kerala, India) were studied. Samples were examined for total aerobic mesophilic count, psychrotrophic count, Vibrios and indicator bacteria. The mean mesophilic counts were in the range of 5.0-5.7 log sub(10)cfu ml super(-1) and 5.6-6.4 log sub(10)cfu g super(-1) respectively for water and clam samples. The shellfish collected from Vembanad lake showed faecal contamination at levels which did not conform to legal standards. The densities of enterococci and Clostridium perfringens were higher in clams than in the growing waters indicating bioconcentration of these organisms in clams. The bacterial flora on newly caught clam consisted of a variety of bacteria of which 28% were Gram-positive and 72% were Gram-negative. Vibrio and Aeromonas together formed 46% of the total mesophilic flora. Vibrio species isolated were V. fluvialis, V. furnissi, V. metsclinikovii. Among Aeromonas species, Aeromonas hydrophila, A. veronii biovar. sobria, A. media, A. coviae were isolated. The remaining Gram-negative genera in the flora belonged to Acinetobacte,; Shewanella, Moraxella and Pseudomonas. The Gram-positive flora of clam was constituted by genera Bacillus, Micrococcus, Corynebacterium, and Arthrobacter. High prevalence of Escherichia coli, faecal Streptococci and C. perfringens in water and clam indicates high degree of faecal pollution of the harvesting areas. The isolation of potentially pathogenic bacteria from clams indicates a risk for health of people consuming and also handling raw seafood.
