Pharmaceuticals are triggering microbial resistance in urban streams

Science
Jan. 9 (UPI) -- Microbial communities in urban streams are developing resistance to drugs as a result of pharmaceutical pollution.When a team of researchers measured pollution levels in a group of streams as part of the Baltimore Ecosystem Study, they found urban streams hosted a greater variety and larger concentration of drugs than suburban streams.Scientists used passive sensors, which measure levels of painkillers, stimulants, antihistamines, and antibiotics over a two-week period. Researchers also measured the responses of microbial samples to caffeine, cimetidine, ciprofloxacin and diphenhydramine."Stream microbial communities are sensitive to pharmaceuticals, which can suppress both respiration and primary production," John J. Kelly, a researcher at Loyola University Chicago, said i...
