Antibiotic susceptibility, detection of sul gene types and presence of class 1, 2 and 3 integrons and gene cassettes using PCR assays were investigated in 3456 Escherichia coli isolates obtained from 38 sampling sites of the Dongjiang River catchment in the dry and wet seasons. 89.1% of the isolates were resistant and 87.5% showed resistance to at least three antibiotics. sul2 was detected most...

Acinetobacter baumannii is an important nosocomial pathogen that often complicates treatment because of its high level of resistance to antibiotics. Though plasmids can potentially introduce various genes into bacterial strains, compared to other Gram-negative bacteria, information about the unique A. baumannii plasmid repertoire is limited. Here, whole genome sequence data was used to determin...

High concentrations of residual arsanilic acid occur in pig manure due to its use in feed to promote growth and control diseases. This study compared the effects of arsanilic acid at three concentrations (0, 325, and 650mg/kg dry pig manure) on the abundance of antibiotic resistance genes (ARGs) and the microbial community during anaerobic digestion. Addition of 650mg/kg arsanilic acid enhanced...

Using a rapid screening method, we investigated the prevalence of fecal carriage of antimicrobial drug-resistant Escherichia coli in 3,174 healthy children from 4 urban settings in Peru and Bolivia. High resistance rates were observed for ampicillin (95%), trimethoprim-sulfamethoxazole (94%), tetracycline (93%), streptomycin (82%), and chloramphenicol (70%). Lower resistance rates were observed...

Background: Salmonella is an important foodborne pathogen that causes diarrhea in humans worldwide. Objectives: This study aimed to determine the serotype distribution, antibiotic-resistant genes, and pathogenicity island (SPI) genes of clinical isolates Weifang. Methods: A total 111 strains were collected from Weifang People’s Hospital between 2018 2020 subjected serotyping using Kauffmann-Whi...

Broiler breeder farms could be a reservoir of Escherichia coli, disseminating antimicrobial resistance and virulence factors. We investigated the E. coli from nine broiler characterised their genes. A total 256 showed high level to tetracycline, nalidixic acid, ampicillin, cephalothin, followed by trimethoprim–sulfamethoxazole chloramphenicol. The trimethoprim–sulfamethoxazole, chloramphenicol ...

The occurrence and removal of 49 antibiotics 11 selected antibiotic resistance genes (ARGs) were investigated in 2 vertical subsurface flow (VF) constructed wetlands (1.5 m2 each): an unsaturated (UVF) unit a partially saturated (SVF) (0.35 m out 0.8 m) operating parallel treating urban wastewater. Thirteen detected influent wastewater, 6 which present all samples. SVF showed statistical signif...
