Meat ducks as carriers of antimicrobial-resistant harboring transferable R plasmids.
J Vet Sci
September 2024
Research Unit for Microbial Food Safety and Antimicrobial Resistance, Department of Veterinary Public Health, Faculty of Veterinary Science, Chulalongkorn University, Bangkok 10330, Thailand.
Importance: Antimicrobial resistance (AMR) is a serious public health threat. AMR bacteria and their resistance determinants in food can be transmitted to humans through the food chain and by direct contact and disseminate directly to the environment.
Objective: This study examined the AMR characteristics and transferable R plasmids in isolated from meat ducks raised in an open-house system.
Genome sequence of Vibrio anguillarum isolates carrying a novel class A β-lactamase VAN-1: do migratory fish transport novel resistance factors?
J Glob Antimicrob Resist
March 2023
Department of Contaminants and Biohazards, Institute of Marine Research, Bergen, Norway. Electronic address:
Objectives: The aim of the study was to understand the genetic basis of resistance of five β-lactam resistant Vibrio anguillarum isolates obtained from the gut content of Atlantic mackerel (Scomber scomberus), using whole genome sequencing and to characterize a novel β-lactamase (VAN-1) from these isolates.
Method: Antibiotic sensitivity pattern was determined using Sensititre™ plates and whole genome sequencing was carried out using Illumina MiSeq-based sequencing. The bla gene was synthesized and expressed in Escherichia coli Top10 cells.
Serum resistance factors in avian pathogenic mediated by ETT2 gene cluster.
Avian Pathol
February 2022
Anhui Province Key Laboratory of Veterinary and Disease Control, College of Animal Science and Technology, Anhui Agricultural University, Hefei, People's Republic of China.
Serum resistance is a poorly understood but common trait of some systemic disease pathogenic strains of bacteria. In this study, we analysed the role type III secretion system 2 (ETT2) of avian pathogenic (APEC) in serum resistance by bacteria survival number in serum culture, mRNA Seq and Tandem Mass Tag™ (TMT™) detection, lipopolysaccharide (LPS) extraction, and biofilm formation detection. We found that the ETT2 gene cluster deletion strain (ΔETT2) is more resistant to the killing effect of serum than wild-type APEC40.

The Hospital for Tropical Diseases, Wellcome Trust Major Overseas Programme, Oxford University Clinical Research Unit, Ho Chi Minh City, Vietnam.
Despite the sporadic detection of fluoroquinolone-resistant Shigella in Asia in the early 2000s and the subsequent global spread of ciprofloxacin-resistant (cipR) Shigella sonnei from 2010, fluoroquinolones remain the recommended therapy for shigellosis. The potential for cipR S. sonnei to develop resistance to alternative second-line drugs may further limit future treatment options.

Research Department of Pharmaceutical and Biological Chemistry, UCL School of Pharmacy, London, UK. Electronic address:
Ethnopharmacological Importance: Capsicum and ginger are used widely in human diets and in folklore medicines. Chemically, gingerol is a relative of capsaicin and both classes of compounds are notable for their spiciness and characteristic pungent aroma. Previous studies have demonstrated that these compounds contain antimicrobial compounds with robust pharmacological importance.
