Project description:Incomplete antibiotic removal in pharmaceutical wastewater treatment plants (PWWTPs) could lead to the development and spread of antibiotic-resistant bacteria (ARBs) and genes (ARGs) in the environment, posing a growing public health threat. In this study, two multiantibiotic-resistant bacteria, Ochrobactrum intermedium (N1) and Stenotrophomonas acidaminiphila (N2), were isolated from the sludge of a PWWTP in Guangzhou, China. The N1 strain was highly resistant to ampicillin, cefazolin, chloramphenicol, tetracycline, and norfloxacin, while the N2 strain exhibited high resistance to ampicillin, chloramphenicol, and cefazolin. Whole-genome sequencing revealed that N1 and N2 had genome sizes of 0.52 Mb and 0.37 Mb, respectively, and harbored 33 and 24 ARGs, respectively. The main resistance mechanism in the identified ARGs included efflux pumps, enzymatic degradation, and target bypass, with the N1 strain possessing more multidrug-resistant efflux pumps than the N2 strain (22 vs 12). This also accounts for the broader resistance spectrum of N1 than of N2 in antimicrobial susceptibility tests. Additionally, both genomes contain numerous mobile genetic elements (89 and 21 genes, respectively) and virulence factors (276 and 250 factors, respectively), suggesting their potential for horizontal transfer and pathogenicity. Overall, this research provides insights into the potential risks posed by ARBs in pharmaceutical wastewater and emphasizes the need for further studies on their impact and mitigation strategies.

Project description:This data is part of a pre-publication release. For information on the proper use of pre-publication data shared by the Wellcome Trust Sanger Institute (including details of any publication moratoria), please see http://www.sanger.ac.uk/datasharing/ Teladorsagia circumcincta, the brown stomach worm, is the most important gastro-intestinal parasite of sheep in temperate regions and is present on 100% of sheep farms in the UK. Infection with T. circumcincta causes a spectrum of disease in the host, ranging from weight loss to death, and results in significant production losses. Parasitic disease is currently controlled by treatment with anthelmintics but resistance to these drugs is widespread and threatens the viability of the livestock industry. There are now well-documented cases of UK farms harbouring triple-resistant T. circumcincta, which can no longer be controlled by any of the three major anthelmintic classes, forcing farmers to abandon sheep rearing. High-throughput sequencing of life stages of T. circumcincta will be used for gene finding and transcriptome analysis.

Project description:Study generating and describing the faecal metagenomes of 194 persons occupationally exposed to antimicrobial resistance in livestock (including 46 control subjects).
Highlights:
- DNA of faecal samples of 194 persons occupationally exposed to antimicrobial resistance (AMR) in livestock, i.e. persons living or working on pig and poultry farms and pig slaughterhouse workers and control subjects, was sequenced and metagenomically analysed.
- The faecal resistomes and microbiomes of farmers and slaughterhouse workers were described and compared between occupationally exposed groups and controls.
- We found an increased ARG carriage in persons working in the Dutch pork production chain as compared to poultry farmers and controls.
- Significant differences were found in the resistome and bacteriome composition of pig and pork exposed workers compared to a control group, as well as within-population (farms, slaughterhouse) compositional differences.
- On-farm working hours and working or living on a pig farm (versus poultry farm) are determinants for the human faecal resistome.
- Direct or indirect contact with AMR in livestock may be a determinant for human ARG carriage.

Project description:We aimed to elucidate the effects of feeding condition (indoor grain-feeding vs. grazing on pasture) on c-miRNAs in Japanese Black (JB) cattle (Wagyu). The cattle at 18 months old were divided into pasture feeding and conventional indoor grain feeding for 5 months. Microarray analysis of c-miRNAs from the plasma extracellular vesicles led to the detection of a total of 202 bovine miRNAs in the plasma, including 15 miRNAs that differed between the feeding conditions.
