Aquatic indicator bacteria in the high alpine zone [PDF]
Selected waters from the high alpine zone within Grand Teton National Park, Wyoming, were analyzed for populations of indicator bacteria during the past three summers to determine the influence of various factors on the quality of these waters. In general the water quality was not significantly influenced by the presence or absence of human visitors ...

Faecal indicator bacteria in river biofilms
Biofilms in surface waters primarily consist of allochthonous microorganisms. Under conditions of pollution faecally derived bacteria may interact with these biofilms. Total coliform bacteria, Escherichia coli and intestinal enterococci are used to monitor source water quality, indicating faecal pollution and the possible presence of enteric pathogens.

Microbial Growth Study on Pork Loins as Influenced by the Application of Different Antimicrobials
The use of antimicrobials in the pork industry is critical in order to ensure food safety and, at the same time, extend shelf life. The objective of the study was to determine the impact of antimicrobials on indicator bacteria on pork loins under long ...

The Effect of Cadmium on Indicator Bacteria in Sewage
The effect of cadmium (Cd) on the number of different faecal indicator bacteria in sewage, and on species composition of different indicator bacteria, was studied. Different amounts of Cd were added to aliquots of a sewage sample, and after 0, 4% and 24 h of Cd exposure at 20°C conforms, faecal coliforms, faecal streptococci and Clostridium perfringens

Effect of sunlight on survival of indicator bacteria in seawater [PDF]
The stability of the natural populations of fecal coliforms and fecal streptococci in raw sewage diluted 1:1,000 in seawater or phosphate-buffered water at 24 +/- 2 degrees C was markedly affected by the absence or presence of sunlight. In the absence of sunlight, these bacteria survived for days, whereas in the presence of sunlight 90% of the fecal ...

Development and testing of a risk indexing framework to determine field-scale critical source areas of faecal bacteria on grassland. [PDF]
This paper draws on lessons from a UK case study in the management of diffuse microbial pollution from grassland farm systems in the Taw catchment, south west England. We report on the development and preliminary testing of a field-scale faecal indicator

Antimicrobial resistance in commensal Escherichia coli isolated from animals at slaughter
Monitoring of antimicrobial resistance in commensal Escherichia coli (N = 3430) isolated from slaughtered broilers, laying hens, turkeys, swine, and cattle in Poland has been run between 2009 and 2012.

Mutational Signatures Indicative of Environmental Stress in Bacteria [PDF]
Evolutionary innovations are dependent on mutations. Mutation rates are increased by adverse conditions in the laboratory, but there is no evidence that stressful environments that do not directly impact on DNA leave a mutational imprint on extant genomes.

Data on antimicrobial resistance (AMR) in zoonotic and indicator bacteria from humans, animals and food are collected annually by the EU Member States (MSs), jointly analysed by EFSA and ECDC and reported in a yearly EU Summary Report.
