this study evaluates the influence of yanã½klar creek on the water quality of fethiye gulf. accordingly, this study demonstrates (i) change in the water quality of fethiye gulf from 2006 to 2007; (ii) the water quality classification of the yanã½klar creek feeding fethiye gulf; and (iii) how land-based fish farm influences yanã½klar creek water quality in a fethiye-gã¶cek specially protected ar...
Evaluating Coliform Monitoring Strategies for Contamination Scenarios in a Distribution System Model
Large public water utilities currently are required to take several 100 mL water samples every month in their distribution systems and to test these samples for the presence of total coliforms to comply with the Total Coliform Rule. How and where they take these samples is not specified. The Total Coliform Rule is currently undergoing review and revision. One possible revision is more specific ...
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...
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...
The shrimp sector is the second largest export earner for Bangladesh, which is a major contributor in the national economy of Bangladesh. It also provides millions of employment. Every year a huge amount of shrimps are rejected to export due to its pathogenic bacterial contamination. A comparative study regarding prevalence and antimicrobial susceptibility of pathogenic bacteria in the black ti...
Escherichia coli, total coliform, and fecal coliform population data were collected from two wastewater treatment facilities, a subsurface flow artificial wetlands, and a receiving stream. Results are presented from individual wastewater treatment process streams, final effluent, and river sites upstream and downstream of the treatment [ acilities. The QuantiTray technique with 4-mcthylumbellif...
The aim of this article was to define the sampling level and method combination that captures antibiotic resistance at pig herd level utilizing qPCR antibiotic resistance gene quantification and culture-based quantification of antibiotic resistant coliform indicator bacteria. Fourteen qPCR assays for commonly detected antibiotic resistance genes were developed, and used to quantify antibiotic r...
BACKGROUND Samples of drinking water were collected directly from the personal water bottles of students at an elementary school in Calgary, Alberta. METHODS Total and fecal coliforms and heterotrophic bacteria were enumerated using membrane filtration and agar plate count methods respectively. RESULTS The Canadian Drinking Water Quality Guidelines (CWQG) criterion was exceeded for total co...
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...
The Honolulu Board of Water Supply (HBWS) selectively chlorinates half of its groundwater supply to provide drinking water that meets the Total Coliform Rule. The objective of this study was to determine whether the groundwater sources used by HBWS are vulnerable to contamination with fecal matter and would require routine disinfection. Larger volumes (1,000 mL) of samples from groundwater and ...
