Fecal 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 کاملRelease of sediment-bound fecal coliforms by dredging.
Fecal coliform concentrations increased significantly (F test) in the immediate vicinity of a maintenance dredging operation in the Mississippi River navigation channel. Increased counts were attributed to the disturbance and relocation of bottom sediments by dredging and a concomitant release of sediment-bound fecal coliforms.
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 ...

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 کاملEvaluation of Methods for Detecting Coliforms and Fecal Streptococci in Chlorinated Sewage Effluents
Total coliform (TC), fecal coliform (FC), and fecal streptococcus (FS) recoveries in chlorinated secondary sewage effluents were investigated by the membrane filter (MF) and multiple-tube (most probable number, MPN) methods. The LES two-step MF method was found to be comparable to the MPN procedure for determining TC. The TC detection was 1.5 times greater by the LES two-step technique than tha...
