Comparative predictive modelling of the occurrence of faecal indicator bacteria in a drinking water source in Norway.

Science of the Total Environment, 2018
Presently, concentrations of fecal indicator bacteria (FIB) in raw water sources are not known before water undergoes treatment, since analysis takes approximately 24h to produce results.

Usefulness of indicator bacteria as potential marker of Campylobacter contamination in broiler carcasses.

Journal of food microbiology, 2018
According to Regulation (EC) No 2017/1495, amending Regulation (EC) No 2073/2005, a slaughterhouse process hygiene criterion based on a limit of 103 CFU/g of Campylobacter for no more than 20 (for the years 2018 and 2019), 15 (for the years 2020-2024 ...

Bioluminescent Bacteria as Indicators of Chemical Contamination of Coastal Waters

Journal of Environmental Quality, 2005
ABSTRACTThe ratio of bioluminescent to total bacteria (bioluminescent ratio, BLR) as an indicator of a variety of types of anthropogenic contamination of estuarine ecosystems was evaluated through a series of laboratory and field studies. Laboratory studies indicated that the BLR of natural bacterioplankton communities was proportionally reduced in the

Prevalence and Persistence of Antimicrobial Resistance in Broiler Indicator Bacteria

Microbial Drug Resistance, 2010
This study explored the prevalence and persistence of acquired antimicrobial resistance in Escherichia coli and Enterococcus faecium from healthy broilers. In 32 broiler farms, cloacal samples were taken during two production rounds, with one production

Application of a tetrazolium dye as an indicator of viability in anaerobic bacteria

Journal of Microbiological Methods, 1999
The use of the redox dye 5-cyano-2,3,-ditolyl tetrazolium chloride (CTC) for evaluating the metabolic activity of aerobic bacteria has gained wide application in recent years. In this study, we examined the utility of CTC in capturing the metabolic activity of anaerobic bacteria.

Ecological Control of Fecal Indicator Bacteria in an Urban Stream

Environmental Science & Technology, 2009
Fecal indicator bacteria (FIB) have long been used as a marker of fecal pollution in surface waters subject to point source and non-point source discharges of treated or untreated human waste. In this paper, we set out to determine the source(s) of elevated FIB concentrations in Cucamonga Creek, a concrete-lined urban stream in southern California ...

Water quality indicators: bacteria, coliphages, enteric viruses

International Journal of Environmental Health Research, 2013
Water quality through the presence of pathogenic enteric microorganisms may affect human health. Coliform bacteria, Escherichia coli and coliphages are normally used as indicators of water quality. However, the presence of above-mentioned indicators do not always suggest the presence of human enteric viruses.

[25] Luminous bacteria as an oxygen indicator

1978
Publisher Summary This chapter discusses luminous bacteria as oxygen indicators. The high oxygen affinity of the luminous system of the bacteria does not reside in any special speed of reaction of the luciferase system with oxygen over and above that of cytochrome oxidase; it relies specifically upon the low turnover number of the system.
