TL;DR: A new library-dependent MST method that uses pyrosequencing-derived shared operational taxonomy units (OTUs) to define sources of fecal contamination in waterways and indicated that analysis of shared OTUs derived from barcoded pyro sequencing reads provide the necessary resolution and discrimination to be useful as a next generation platform for microbial source tracking studies.

TL;DR: This study demonstrates that many ARGs and HMRGs may persist the treatment processes in WWTPs and their association to MGEs may contribute to the dissemination of resistance genes among microorganisms in the environment.

TL;DR: E. coli strains in phylogenetic group B2 were rarely found in humans and domesticated animals in Jeonnam Province, South Korea, and that the majority of strains containing virulence genes belonged to phylogenetics group B1 and were isolated from beef cattle.

TL;DR: Findings suggest that restriction of the use of antibiotics in food animal operations in South Korea, especially those involved in poultry and swine production would be desirable.

TL;DR: Two recently developed, next-generation-sequencing (NGS)-based MST approaches to identify sources of fecal pollution in recreational waters are discussed, both of which require optimized sequence processing methodologies and are influenced by primer selection for amplicon sequencing.
