occurrence of microbial indicators and clostridium perfringens in wastewater, water column samples, sediments, drinking water, and weddell seal feces collected at mcmurdo station, antarctica.	mcmurdo station, antarctica, has discharged untreated sewage into mcmurdo sound for decades. previous studies delineated the impacted area, which included the drinking water intake, by using total coliform and clostridium perfringens concentrations. the estimation of risk to humans in contact with the impacted and potable waters may be greater than presumed, as these microbial indicators may not be the most appropriate for this environment. to address these concerns, concentrations of these and ...	2004	15574926
escherichia coli out in the cold: dissemination of human-derived bacteria into the antarctic microbiome.	discharge of untreated sewage into antarctic environments presents a risk of introducing non-native microorganisms, but until now, adverse consequences have not been conclusively identified. here we show that sewage disposal introduces human derived escherichia coli carrying mobile genetic elements and virulence traits with the potential to affect the diversity and evolution of native antarctic microbial communities. we compared e. coli recovered from environmental and animal sources in antarcti ...	2016	27179324
