Artificial neural networks (ANN) are modelling tools that can be of great utility in studies of microbial water quality. The ability of ANNs to work with complex, inter-related multiparameter databases and provide superior predictive power in non-linear relationships suits their application to microbial water quality studies. To date ANNs have been successfully applied (a) for the prediction of...

The Buffalo River and its dams are major surface water sources used for fresh produce irrigation, raw water abstraction and recreation in parts of the Eastern Cape Province in South Africa. Over a 12-month period (August 2010 to July 2011), we assessed the bacteriological qualities of water from the river and 3 source water dams along its course. Faecal indicator bacteria (FIB), including total...

FAILURE of treatment of urinary infections due to faecal streptococci in association with other bacteria (Garrod, Shooter and Cunven, 1954) has indicated the need for combined antibiotic therapy in these cases (Eisenberg, Alexander and Flippin, 1953). The incidence of streptococci in mixed urinary infections appears to vary from 10 per cent. (Sanford et aZ., 1956) to 22.4 per cent. (Rantz and K...

Background: The vegetables provide important nutrients to human beings. Nevertheless, contaminated vegetables can cause health problems because of their microbial load. The aim of this study was to assess the microbial quality of three main leafy vegetables cultivated and consumed at Porto-Novo in Republic of Benin. Methods: Totally, 36 samples of amaranth, nightshade, and lettuce were taken f...

A bacteriological study of three ponds in Uegwere Bo-ue community, Khana Local Government Area, of Rivers State, Nigeria were investigated to evaluate the water quality of the ponds. Surface water samples were collected monthly for eight months covering both seasons and evaluated. Bacteriological analyses carried out includes: total heterotrophic bacteria counts(THBC), Total coliform counts(TCC...

An investigative study was carried out to determine the bacteriological and physicochemical qualities of borehole and well water samples in Ijebu-Ode, Southwestern Nigeria. Ten water samples each of borehole and well water sources were collected within the geographical location. Physicochemical parameters were determined using standard methods. The total bacterial count was determined by pour p...

This paper deals with the sanitary conditions of the water and bottom sediments in the Lower Vistula river, between Wyszogród and Toruń. The contamination extent of the water and bottom sediments by easily decomposable organic matter and substances of faecal origin have been indirectly estimated by determining the total number of heterotrophic bacteria (TVC 20oC) and the occurrence of the faeca...

Microbiological monitoring of bivalve mollusc production areas by national or regional authorities is usually undertaken as part of a programme to classify the areas according to the perceived risk of the presence of pathogenic microorganisms based on the concentrations of faecal indicator bacteria present in the area. The indicator bacteria used are generally of the coliform group: total colif...

The study was carried out on water samples collected from different sites in Swakin City and Arbat area Sudan. Five were during two seasons (winter summer) to determine the quality of drinking by looking into physicochemical microbial aspect. Results showed that some exceeded Sudanese international standards turbidity presence coliform, E. coli faecal streptococcus bacteria. It is recommended c...

The associated educational institution had reported the growth of a faecal coliform on inhouse testing from its potable reticulated water supply sampled on 9 March 1999 after the repair of a damaged water pipe. On the advice of the Environmental Health Branch of the Department of Human Services, South Australia (DHS SA) water from the suspected system was boiled before consumption until further...
