Bacterial Pathogens Active
The U.S. Geological Survey (USGS) Michigan Bacteriological Research Laboratory (MI-BaRL) studies the source, occurrence, and distribution of the bacterial pathogens Shiga-toxin producing E. coli (STEC), Salmonella, Shigella, Campylobacter, Enterococcus, and Staphylococcus and the relation of occurrence of pathogens with fecal indicator bacteria, land-use, season, hydrology, geology, weather factors (wind direction, wave height), and emerging chemical contaminants. We have conducted several studies that have evaluated surface water and source samples for markers specific to these bacterial pathogens. Pathogens have been studied in surface waters from several different settings including both agricultural and urban environments, rivers, inland lakes, and the Great Lakes. New methods to test for additional bacterial pathogens are continually being developed.
Reports are available for the following studies:
Factors related to occurrence and distribution of selected bacterial and protozoan pathogens in Pennsylvania streams
Pathogenic bacteria and microbial-source tracking markers in Brandywine Creek Basin, Pennsylvania and Delaware, 2009-10
Comparing wastewater chemicals, indicator bacteria concentrations, and bacterial pathogen genes as fecal pollution indicators
Chemical and microbiological water quality of subsurface agricultural drains during a field trial of liquid dairy manure effluent application rate and varying tillage practices, Upper Tiffin Watershed, southeastern Michigan
