Fecal Streptococci in Water'
ROSE, ROBERT E. (Massachusetts Department of Public Health, Amherst), AND WARREN LITSKY. Enrichment procedure for use with the membrane filter for isolation and enumeration of fecal streptococci in water. Appl. Microbiol. 13:106-108. 1965.-By the use of PYC enrichment medium, the recovery of fecal streptococci from river water has been increased more than twofold over that of M-Enterococcus Aga...
متن کاملFluorogenic selective and differential medium for isolation of fecal streptococci.
Of 44 fluorogenic substrates tested for their ability to differentiate species of fecal streptococci, four yielded species-differentiating reactions. The remaining substrates either yielded uniformly positive, negative, or variable strain-dependent reactions. One substrate, 4-methylumbelliferone-alpha-D-galactoside, was hydrolyzed by Streptococcus bovis and S. faecium and its biotypes. 4-Methyl...
متن کاملFecal Coliforms and Fecal Streptococci Contamination of Traditional Ice Cream in Tabriz
Most of present traditional ice cream from hygienic quality has non-conforming with extant standards. Pasteurization of primary ice cream mixture with sufficient thermal processing increase hygienic quality level and causes control of primary infection. Origins of infection for traditional ice cream consist of: use of infected primary materials (milk or cream) or non-pasteurization of them. Stu...
متن کاملEffect of Sediment Particle Size and Temperature on Fecal Bacteria Mortality Rates and the Fecal Coliform/Fecal Streptococci Ratio
Extended survival of fecal bacteria in sediment can obscure the source and extent of fecal contamination in agricultural settings. The variability in fecal coliform/fecal streptococci (FC/FS) ratios with time and discrepancies between observable fecal sources and measured FC/ FS ratios in shallow surface water from agricultural watersheds may be explained by examining FC and FS mortality rates ...
متن کاملThe Interaction between Heterotrophic Bacteria and Coliform, Fecal Coliform, Fecal Streptococci Bacteria in the Water Supply Networks
BACKGROUND This study investigated the interaction between heterotrophic bacteria and coliform, fecal coliforms, fecal streptococci bacteria in water supply networks. METHODS This study was conducted during 2013 on water supply distribution network in Aq Qala City, Golestan Province, Northern Iran and standard methods were applied for microbiological analysis. The surface method was applied t...
