Testing Water for Antibiotic-Resistant Bacteria

Antibiotic-resistant bacteria are an important concern for disease prevention in the future. UA doctoral candidate Victoria Obergh is testing Tucson-area wastewater systems to find out where these bacteria can be found.

In the lab, Victoria Obergh transfers bacterial DNA samples into a tray. A graduate student in the University of Arizona’s Department of Soil, Water and Environmental Science, part of the College of Agriculture and Life Sciences, Obergh works with the samples under a sterile hood sporting an ultraviolet light to kill any unwanted DNA.

Careless Disposal of Antibiotics Can Create Aquatic Superbugs

ANN ARBOR, Mich.—A wastewater treatment plant can provide the perfect mating ground for carelessly disposed of antibiotics to form superbugs that are eventually discharged into streams and lakes, says a University of Michigan researcher.

It’s not the fault of the wastewater treatment plants, says Chuanwu Xi, assistant professor at the U-M School of Public Health. His research team sampled water at five sites in and near Ann Arbor’s Waste Water Treatment Plant and found that the water contained the superbug Acinetobacter, a multidrug-resistant bacterium. The results were first reported by Xi’s group in 2009, and the research is ongoing. (more…)

Potomac River: Ten-fold Increase in Native Submerged Vegetation Reflects Improved Water Quality

The Potomac River in Washington, D.C. is showing multiple benefits from restoration efforts, newly published research suggests. Reduced nutrients and improved water clarity have increased the abundance and diversity of submerged aquatic vegetation (SAV) in the Potomac, according to direct measurements taken during the 18-year field study.
