This study evaluated the bacteria removal efficiency, re-suspension and survivability within two structural Best Management Practices (BMPs) called Vortechs installed at two different sites in Providence, Rhode Island. Twelve rain storms were sampled during years 2004 and 2005. Five pathogenic indicator bacteria, E. coli, enterococci, fecal streptococci, total coliform, fecal coliform, were ana...

With a modified Moore swab for sampling bacteria, Salmonella organisms were recovered consistently from surface waters when the enrichment broths of SBG-sulfa and tetrathionate and Brilliant Green Agar plates were incubated at 41.5 C. When an equal portion of the same swab sample was incubated at 37.0 C, no salmonellae were detected. By use of the elevated-temperature technique, salmonellae wer...

Individuals of the water louse, Asellus aquaticus, enter drinking water distribution systems in temperate parts of the world, where they establish breeding populations. We analysed populations of surface water A. aquaticus from two ponds for associated faecal indicator bacteria and assessed the risk of A. aquaticus transporting bacteria into distribution systems. Concentrations of up to two E. ...

Whether all members of the coliform group of bacteria should be accorded equal sanitary significance has been debated for at least a generation. English and German authorities are disposed to assign special significance to the presence of Escherichia coli, whereas it is the American practice, particularly as applied to water analyses, to consider all coliform bacteria of equal sanitary signific...

GELDREICH E. E. (Division of Water Supply and Pollution Control, U.S. Public Health Service, Cincinnati, Ohio), B. A. KENNER, AND P. W. KABLER. Occurrence of coliforms, fecal coliforms, and streptococci on vegetation and insects. Appl. Microbiol. 12:63-69. 1964.-This study considers the sanitary significance of coliforms, fecal coliforms, and streptococci isolated from 152 species of plants and...

The effect of cereal non-starch polysaccharides (NSP) on the gut microbial populations was studied in 5 growing pigs between 39-116 kg body weight according to a Latin square design. The diets were composed to contain different NSP levels. The control diet had a normal NSP content (139 g/kg dry matter (DM)), 2 diets had a low total amount of NSP (95 and 107 g/kg DM) and 2 diets had a high amoun...

The present study was carried out for microbiological analysis to assess the quality of raw fish sold in the Fishing harbour of Visakhapatnam, East Coast of India. The study was performed during the period of April 2012 to March 2013. Three commonly edible fishes were selected for the microbial analysis to evaluate the quality of fish samples in terms of microbial content, the samples were inoc...

Water is a valued natural resource for the existence of all living organisms. Management of the quality of this precious resource is, therefore, of special importance. In this study river water samples were collected and analysed for physicochemical and bacteriological evaluation of pollution in the Unity Road stream segment of Asa River in Ilorin, Nigeria. Juvenile samples of Clarias gariepinu...

Multiplex PCR amplification of lacZ, uidA and plc genes was developed for the simultaneous detection of total coliform bacteria for Escherichia coli and Clostridium perfringens, in drinking water. Detection by agarose gel electrophoresis yielded a band of 876 bp for the lacZ gene of all coliform bacteria; a band of 147 bp for the uidA gene and a band of 876 bp for the lacZ gene of all strains o...

Microbial quality of air in a dairy processing plant was evaluated to ascertain the contribution of air as a source of contamination and spoilage of milk and milk products. The mean total aerobic counts obtained in the air by sedimentation method were 32.66 ± 3.82, 25.32 ± 4.17 and 33.36 ± 3.53 cfu/ m in raw milk reception dock, pasteurization room and product preparation room respectively. The...
