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...

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...

Effective handwashing with soap requires reliable access to water supplies. However, more than three billion persons do not have household-level access to piped water. This research addresses the challenge of improving hand hygiene within water-constrained environments. The antimicrobial efficacy of alcohol-based hand sanitizer, a waterless hand hygiene product, was evaluated and compared with ...

The objective of this study was to characterize the wastewater from BIAMBA Marie MUTOMBO hospital in terms physico-chemical and bacteriological parameters, set up a pilot UASB reactor treat water. Two methods were used conduct investigations: observation experimentation. Observations focused on management at its surroundings, point discharge into receiving environment. analysis revealed that so...

Pfizer selective enterococcus (PSE) and KF agars were compared for their recovery of fecal streptococci from sewage effluent on membrane filters. The results showed that PSE agar is highly selective for the enterococci. The tan color resulting from esculin hydrolysis, which was not always visible on the surfaces of the colonies, is not considered a necessary differential characteristic on PSE a...

Gentamicin-thallous-carbonate (GTC) agar was formulated by Donnelly and Hartman (Appl. Environ. Microbiol. 35:576-581, 1978) to select for fecal streptococci in sewage and water samples. The present study was conducted to determine the usefulness of GTC agar for the enumeration of fecal streptococci in foods. Comparisons were made with KF streptococcal (KF), Pfizer selective enterococcus (PSE),...

Nonpoint sources of pollution that contribute fecal bacteria to surface waters have proven difficult to identify. Knowledge of pollution sources could aid in restoration of the water quality, reduce the amounts of nutrients leaving watersheds, and reduce the danger of infectious disease resulting from exposure to contaminated waters. Patterns of antibiotic resistance in fecal streptococci were ...
