Monitoring the bacteriological quality of potable waters in hospital

Journal of Hospital Infection, 1988
We report a survey of the bacteriological quality of potable waters from hospitals. In the 12-month period February 1986 to January 1987, 646 samples were examined from 25 hospitals. Coliforms were isolated from eight (1.2%) samples, received from three hospitals.

BACTERIOLOGICAL QUALITY OF CANNERY COOLING WATER

Journal of Food Science, 1977
ABSTRACT Fifty‐nine samples of can‐cooling water from 30 midwestern canneries were examined for aerobic plate count, salmonellae, coagulase‐positive staphylococci, coliforms, enterococci, and mesophilic aerobic and anaerobic (putrefactive) spores including spores of Clostridium botulinum

Bacteriological indicators of tropical water quality

Environmental Toxicology and Water Quality, 1996
In a search for appropriate bacterial indicators of tropical water quality using the membrane filtration technique, four bacterial groups were surveyed. Of these, Aeromonas hydrophila, Vibrio species, and fecal coliforms were consistently isolated from the four surface water sources located in southeastern Nigeria.

Bacteriological quality of water from watercoolers

European journal of water quality, 2006
L'eau destinee a la consommation humaine peut etre distribuee par des fontaines refrigerantes alimentees, soit par un branchement sur le reseau interieur de distribution, soit par des bonbonnes d'une capacite de 18,9 litres. Les fontaines raccordees au reseau doivent etre nettoyees et desinfectees et fonctionner regulierement, le filtre change ...

Bacteriological quality of spring water in Bahrain

The Environmentalist, 1990
The bacteriological quality of untreated spring waters in Bahrain were evaluated. Samples were collected from 12 natural springs and analysed for total plate count, total coliform, total faecal coliform, total faecal streptococci and occurrence ofShigella andSalmonella.

Quality control of membrane filters for bacteriological examination of water

Journal of Applied Bacteriology, 1995
A standard protocol for quality control of membrane filters for bacteriological examination of water is presented. It is based on the screening test proposed by Brenner and Rankin (1990) making use of Enterobacter aerogenes ATCC 49701 as a test strain and tryptone soya agar as medium for ...

Model of fluctuations in bacteriological indices of water quality

Water Resources, 2006
The bacteriological indices of water quality, including coliforms, sulfite-reducing clostridia, total microbial count, coliphages, and fecal streptococci were analyzed. A model describing fluctuations in microorganism population in the aquatic environment is proposed.

Internal quality control samples for water bacteriology

Journal of Applied Bacteriology, 1994
A method is described for the preparation and application of a bacteriological quality control system for use with tests for plate counts and the enumeration of indicator organisms in water. Statistical limits are obtained and control charts prepared which are analagous to those used in analytical chemistry and clinical biochemistry laboratories.

Freshwater mussels as monitors of bacteriological water quality

Water, Air, and Soil Pollution, 1988
A species of commercially obtained freshwater mussel (Elliptio complanata) was shown to actively filter, concentrate, and retain fecal coliform (FC) bacteria from a variety of freshwater stream environments. Fecal coliform densities in mussel viscera were maximum within 48 hr of in situ exposure.

Improving Bacteriological Water Quality Compliance of Drinking Water

2012
Identifying the root cause of bacteriological failures from routine drinking water analyses in the UK is difficult because investigative re-samples are often compliant with the standards. The aim of this paper is to develop understanding of the reasons for sporadic changes in microbiological quality.
