TLDR
R+ bacteria in the hospital discharge were also resistant to a broader spectrum of drugs than those in city sewage, and such drug-resistant pathogens in the water environment could be of particular concern.Abstract:
The number and properties of drug-resistant coliform bacteria in hospital and city sewage were compared. There was little difference in the counts of organisms with nontransferable resistance to one or more of 13 commonly used drugs. An average of 26% of coliforms in hospital waste water had transferable resistance to at least one of the drugs ampicillin, chloramphenicol, streptomycin, sulfonamide, or tetracycline as compared to an average of 4% in city sewage. R(+) bacteria in the hospital discharge were also resistant to a broader spectrum of drugs than those in city sewage. In both effluents, the occurrence of fecal Escherichia coli among R(+) coliforms was twice as high as among coliforms with nontransferable resistance. Resistance was transferable to Salmonella typhi, and such drug-resistant pathogens in the water environment could be of particular concern. The significance of the results with regard to environmental pollution with R(+) bacteria and the dissemination of these organisms is discussed.read more

Trends in human fecal carriage of extended-spectrum β-lactamases in the community: toward the globalization of CTX-M.
TL;DR: It is suggested that CTX-M carriage is evolving toward a global pandemic but is still insufficiently described, and only a better knowledge of its dynamics and biology will lead to further development of appropriate control measures.

TL;DR: The highest resistance rates were found in E. coli strains of a sewage treatment plant which treats not only municipal sewage but also sewage from a hospital, and thus sewage treatment processes contribute to the dissemination of resistant bacteria in the environment.

Transfer of multiple drug resistance plasmids between bacteria of diverse origins in natural microenvironments.
TL;DR: The present study demonstrates that conjugation and transfer of R plasmids is a phenomenon that belongs to the environment and can occur between bacterial strains of human, animal, and fish origins that are unrelated either evolutionarily or ecologically even in the absence of antibiotics.

Potential impacts of disinfection processes on elimination and deactivation of antibiotic resistance genes during water and wastewater treatment
TL;DR: A concise introduction to the significance of ARB and ARG occurrence in environmental systems is provided, coupled with a review of the role that commonly used water and wastewater disinfection processes may play in minimizing ARG transport and dissemination.

Antibiotic Resistance in Acinetobacter spp. Isolated from Sewers Receiving Waste Effluent from a Hospital and a Pharmaceutical Plant
TL;DR: Investigation of the possible increase of antibiotic-resistant bacteria in sewage associated with the discharge of wastewater from a hospital and a pharmaceutical plant found an increase in the prevalence of both single- and multiple-antibiotic resistance among Acinetobacter species in the sewers.
