Quantitative microbial risk assessment of antibiotic resistance genes and mobile genetic elements in orchard soils across South Korea Open
Antibiotic resistance is a global health crisis, but environmental pathways of resistance dissemination to farm workers remain poorly understood. Agricultural soils represent critical but underexplored reservoirs of antibiotic resistance g…

Discovery of an identical CRISPR spacerome in a subset of global <i>E. coli</i> strains spanning decades Open
CRISPR is an immune system in bacteria composed of repeats and spacers. Motivated by the hypothesis that spacer identification can trace circulation routes, we analyzed CRISPR arrays of E. coli from environmental, animal, and clinical sour…

Detection of a genetically related carbapenemase-producing Escherichia coli ST167 in clinical and environmental isolates: Evidence for clonal spread of carbapenemase-producing Enterobacteriaceae in humans and the environment in Iowa, United States Open
The occurrence of BO1 was temporally and spatially close to that of one clinical strain, IA0018, implying the clonal spread of CPEs among humans and the environment, although the source and directionality of this spread remains unknown. Th…

Differentiation of environment and wastewater treatment plants by core antibiotic resistance genes and aadA2 as indicators in South Korea Open
Antibiotic resistance is reportedly disseminated from wastewater treatment plants (WWTPs) into aquatic environments. In this study, it was hypothesized that discharge of effluent from WWTPs may influence resistome of the adjacent aquatic e…

Prevalence and Characterization of CRISPR Locus 2.1 Spacers in Escherichia coli Isolates Obtained from Feces of Animals and Humans Open
We characterized spacers of CRISPR locus 2.1 in E. coli isolates obtained from the feces of various sources. Phage-derived CRISPR spacers are mainly acquired from the order Caudovirales, and plasmid-derived CRISPR spacers are mostly from t…

Resistome Study in Aquatic Environments Open
Since the first discovery of antibiotics, introduction of new antibiotics has been coupled with the occurrence of antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs). Rapid dissemination of ARB and ARGs in the aquati…

Dynamics of Genotypic and Phenotypic Antibiotic Resistance in a Conventional Wastewater Treatment Plant in 2 Years Open
Wastewater treatment plants (WWTPs) are considered a sink and a source of antibiotic resistance. In this study, we applied both culture-dependent and SmartChip-based culture-independent approaches for the investigation of antibiotic-resist…

Geographical distribution and genetic diversity of Bradyrhizobium spp. isolated from Korean soybean root nodules Open
This study investigated the distribution and genetic diversity of the indigenous Bradyrhizobium spp. in the Korean agricultural field. A total of 254 Bradyrhizobium strains were isolated from 97 soybean samples (9 cultivars) collected in 1…

Emergence of High Level Carbapenem and Extensively Drug Resistant Escherichia coli ST746 Producing NDM-5 in Influent of Wastewater Treatment Plant, Seoul, South Korea Open
High level carbapenem and extensively drug resistant (XDR) Escherichia coli strain N7, which produces a variant of New Delhi metallo-β-lactamase (NDM-5), was isolated from the influent of the Jungnang wastewater treatment plant located on …
