Theprevalence and seasonal variation of bacterial indicators of faecal pollution such as total coliform bacteria, faecal coliform bacteria, Escherichia coli and faecal streptococci were investigated in samples of water and beach sand from the four fish landing centres of Thoothukudi. Further the samples were screened for Salmonella to study the reliability of faecal indicator bacteria as an ind...

Objective: The present study investigates the diversity, and distribution of harmful microbes in sediments and groundwater of Tuticorin Corporation. The faecal pollution indicators such as, Total coliform bacteria, Faecal coliform bacteria, Escherichia coli, Faecal streptococci were investigated in the sediments and groundwater samples from 12 locations in the study area. Methods: Groundwater a...

A diurnal study was undertaken in April 2014 to record the bacterial density and some of the physicochemical factors of the river Ganga near Ichapore, West Bengal, India. The pollution indicating bacteria (total coliform, faecal coliform and faecal streptococci) were found in maximum numbers at 14.00 hrs and minimum at 20.00 hrs. All the bacterial populations were abundant and showed diel rhyth...

Three different approaches for establishing guidelines for the microbiological quality of treated wastewater that is reused for agriculture are reviewed. These approaches have different objectives as their outcomes: the absence of faecal indicator organisms in the wastewater, the absence of a measurable excess of cases of enteric disease in the exposed population and a model-generated estimated...

The aim of this experiment was to study the effect of the application of pig slurry on potential pathogen (total and faecal coliform bacteria) presence in a Typic Xerofluvent soil. The experiment was conducted in field conditions, in the Segura River valley in the South East of Spain. Four treatments, in a fully-randomised design with three replicates per treatment, were established in experime...

BACKGROUND Indiscriminate disposal of untreated wastes which are often heavily laden with sewage microorganisms some of which are pathogenic to humans into aquatic environments near cities could serve as potential dangers to human health. OBJECTIVE A prospective study was undertaken to investigate the scope of potential bacterial pathogens and to assess the extent of pollution of the Douala l...

Background: In Addis Ababa, where irrigation water for vegetable production is commonly derived from the highly polluted Akaki river, information on microbial contamination of water and irrigated vegetable is scanty. An assessment was done to determine the microbiological quality of irrigation water and lettuce harvested from 10 urban farming sites of Addis Ababa. The efficacy of 5 lettuce wash...

Bacteriological water quality status in terms of total coliform and faecal coliform count was studied on both--east and west banks of river Yamuna in Delhi. Membrane filtration technique was adopted for enumeration of total coliform and faecal coliform count in the river water sample collected on monthly basis for 2 years--2002 and 2003. The study reveals the impact of diverse anthropogenic act...

OBJECTIVE To assess the bacteriological and physical quality of locally packaged drinking water sold for public consumption. METHODS This was cross-sectional study where a total of 60 samples of bottled water from 10 brands and 30 samples of sachet water from 15 brands purchased randomly were analyzed for bacteriological contamination (total coliform and faecal coliform per 100 mL) using memb...
