    Occurrence of vibrio and other pathogenic bacteria in Mytilus galloprovincialis and Venus gallina harvested from the Marmara Sea
    (Tubitak Scientific & Technological Research Council Turkey, 2005) Yilmaz, I; Bilgin, B; Öktem, B
    The objective of this research was to determine microbiological quality of the Mytilus galloprovincialis and Venus gallina harvested in the Marmara Sea (Gelibolu Region). The samples were examined for total aerobic mesophilic bacteria (TAMB), coliform group bacteria, Escherichia coli, Staphylococcus aureus, Salmonella spp., Vibrio cholerae, and Vibrio parahaemolyticus. The microbiological analysis showed 2.1 x 10(4) - 1.9 x 10(6) cfu/g TAMB, 2.9 x 10(2) - 8.2 x 10(3) cfu/g coliform group bacteria, 78 - 2.5 x 10(2) cfu/g E. coli, 3.1 x 10(2) - 1.1 x 10(3) cfu/g S. aureus for the Mytilus galloprovincialis - Venus gallina mussels samples respectively. Salmonella spp., Vibrio cholerae and Vibrio parahaemolyticus were not detected in any samples examined. In general, Venus gallina samples had higher TAMB, coliform group bacteria, E. coli and S. aureus counts than the Mytilus galloprovincialis samples. The study confirms the risk associated with the consumption of mussels and the need of proper storage and preparation conditions prior to consumption. In addition, in order to prevent the health risks associated with mussels, heat treatment has to be applied prior to consumption.

    Some characteristics of Lactobacillus isolates from infant faeces
    (Academic Press Ltd Elsevier Science Ltd, 2004) Arici, M; Bilgin, B; Sagdic, O; Ozdemir, C
    In this research, 21 strains of lactobacilli were isolated from newborn infant faeces. Lactobacillus rhamnosus (seven strains), L. paracasei ssp. paracasei (four strains), L. fermentum (four strains), L. buchneri (two strains), L. brevis (one strain), L. curvatus (one strain) and Lactobacillus sp. (two strains) isolated from infant faeces were analysed for acid production, antibiotics resistances, H2S productions and antimicrobial activities. Inhibition activity of bacteriocins and/or bacteriocin-like substances of the lactobacilli against some food contaminants and pathogenic bacteria (Escherichia coli, Staphylococcus aureus ATCC 28213, S. aureus ATCC 2392, Yersinia enterocolitica and Bacillus cereus) were determined by the agar diffusion method.
