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...

Genetically feathered and featherless sibling broilers selected for matched BW were killed, scalded, and defeathered to determine the consequences of feathers and empty feather follicles on the recovery of bacteria from carcass breast skin. In trial 1, the vents of all carcasses were plugged and sutured before scalding to prevent the expulsion of cloacal contents during picking. In trial 2, hal...

Four brands of membrane filters were examined for total and fecal coliform recovery performance by two experimental approaches. Using diluted EC broth cultures of water samples, Johns-Manville filters were superior to Sartorius filters for fecal coliform but equivalent for total coliform recovery. Using river water samples, Johns-Manville filters were superior to Sartorius filters for total col...

Background and Objective: Hospital waste water due to infectious organisms and other risk factors is important. In this study, the possibility of coliform bacteria removal from hospital waste water using ozone separately and combining with hydrogen peroxide (H2O2 + O3) as a pre-treatment was investigated. Material and Methods: This is an experimental study that in the second moiety of 1392 i...

Contamination of surface waters with fecal bacteria from grazinglands is a component of nonpoint source agricultural pollution. Methods are needed to limit the movement of fecal bacteria from grazinglands into surface water. We used two experimental watersheds to test for impact of cattle on total coliform, E. coli, and enterococci bacteria numbers. Grazing cattle elevated these microbe numbers...

a new medium, termed ecol was developed for the detection and enumeration of e. coli. the selective properties of ecol medium for the detection of e.coli from mixed culture in wastewater was tested and compared with conventional coliform media at 37°c and 44°c. results clearly showed that ecol medium was enable to direct confirmation of e.coli to be carried out by the indole reaction. the resul...

The aims of this study were to determine the total population of coliform bacteria in the samples collected from diarrhea associated patients from the local area of Bangladesh and to examine the antibacterial efficacy of leaf extracts of Moringa oleifera (Moringaceae) against the isolated coliform bacteria. The coliform bacteria detected in these samples by some microbial-biochemical tests such...

Bacteria were quantified in samples of drinking-water and in two porridges prepared for infant-feeding [fortified instant soy-rice porridge (SRP) and cooked porridge (Lishe bora, LB)] in 54 households. Bacterial numbers were measured again after the porridges had been held at room temperature for four hours (T4). Findings were benchmarked against bacterial numbers in traditional complementary f...
