Statewide Assessment of Iowa Streams Links Landscape Characteristics to Antibiotic Resistance Signatures
U.S. Geological Survey (USGS) scientists conducted the first statewide assessment of antibiotics, antibiotic resistant bacteria (ARB), and antibiotic resistant genes (ARGs) in streams (water column and bed sediment samples) across Iowa. Results indicated that ARB and ARGs were prevalent, and a combination of watershed characteristics (such as land use, livestock population, and human population)...
Bacteriological Research Core Technology Team
About the Research The Michigan Bacteriological Research Laboratory (MI-BaRL) Core Technology Team (CTT) as part of the Environmental Health Program uses a wide array of traditional and modern molecular approaches to evaluate microbial pathogens and antimicrobial resistance pathways in the environment. The scientists use these approaches to advance the understanding of how environmental...
Environmental detection of avian influenza virus
A collaborative project with Federal and university partners working toward the goal of understanding avian influenza viruses (AIVs) in the environment: early detection, enhancing biosurveillance, and mitigation to reduce spread into domestic poultry and potential occupational or recreational exposure to humans.
A National Assessment of Pesticide, PFAS, Microplastic, and Antibiotic Resistance Gene Exposures in White-Tailed Deer
Research has documented exposures and consequential environmental health effects of pesticides, PFAS, microplastics, and antibiotic resistance genes in environmental biota. Little is known, however, regarding such effects in white-tailed deer ( Odocoileus virginianus ).
Collaborative Science Provides Understanding of Contaminants in Bottled Water-an Increasingly Common Alternate Drinking Water Source
U.S. Geological Survey researchers and public health experts collaborated to determine what contaminants occur in bottled water, which is an increasingly common alternate drinking water source, to broaden their understanding of human exposure to contaminants in drinking water supply chains. Bottled water, like public-supply and private-well tap water supply chains, contained multiple organic...
Costs and Benefits of Nitrapyrin
In December 2020, our research group (as part of the Food Integrated Science Team) published a review of nitrapyrin costs and benefits in the journal Environmental Science & Technology .
Southwest Wisconsin Groundwater and Geology (SWIGG) study
The fractured bedrock aquifers of southwest Wisconsin are often overlain by shallow soils, so private wells are potentially vulnerable to contamination by nitrate and pathogens from the land surface. The goal of this study is to evaluate the extent and causes of private well water contamination in three southwest Wisconsin counties.
Bacterial Pathogens
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...
Enhance Great Lakes Beach Recreational Water Quality Decision Making
Important questions about beach closures and management remain unanswered in the Great Lakes where over 500 beaches are routinely used along the nearly 11,000 miles of coastline. The economies of coastal areas are dependent on public confidence in the quality of water at the shoreline, and beach managers need reliable science-based information to make beach closure and beach management decisions...
Antibiotic Resistance
The U.S. Geological Survey (USGS) Michigan Bacteriological Research Laboratory (MI-BaRL) conducts research on antibiotic-resistant bacteria and their genes. We have concentrated our studies on antibiotic-resistant bacteria of human-health concern, including vancomycin-resistant enterococci, methicillin-resistant Staphylococcus aureus ( MRSA ), and Klebsiella and E. coli resistant to third...
Microbial Source Tracking
It is often important to understand the source of fecal indicator bacteria, pathogens, or chemicals that impair the normal use of water. Antibiotic-resistant bacteria and their genes, specific bacterial pathogens (such as E. coli O157:H7 which is primarily associated with cattle), and host-associated bacterial genes (such as human or animal specific Bacteroides genes), can be used to evaluate the...
Microbiological Water Quality
Recreational water and industrial discharges are regulated by other federal and state agencies across the country. The U.S. Geological Survey (USGS) Michigan Bacteriological Research Laboratory (MI-BaRL) conducts studies to understand the fate and transport of fecal indicator bacteria in surface and groundwater to aid state and federal partners. A variety of standardized protocols are used to...

USGS Analyst Performs DNA Extractions in a Laboratory
A U.S. Geological Survey analyst performs DNA extractions on enriched cultures of water from the study area. Once the DNA was extracted it was used to detect pathogen gene markers using polymerase chain reaction (PCR).
