Background: Antimicrobial resistance (AMR) is a global health concern that is exacerbated by the transmission of bacteria and genetic material between humans, animals and the environment. This study investigated AMR of Escherichia coli (E. coli) isolated from cats' feces and their drinking water.

During the production cycle of poultry farms, pathogens may remain in the next cycle of rearing young chickens. This study was conducted at three industrial chicken farms (A, B, and C) in central Thailand. Results showed that the percentages of during the resting period in farms A, B, and C were 28.

Background And Aim: The emerging of antimicrobial-resistant foodborne bacteria is a serious public health concern worldwide. This study was conducted to determine the association between farm management systems and antimicrobial resistance profiles of isolated from conventional swine farms and natural farms. isolates were evaluated for the minimum inhibitory concentration (MIC) of 17 antimicrobials, extended-spectrum beta-lactamase (ESBL)-producing enzymes, and plasmid-mediated colistin-resistant genes.

PCR amplification of the nearly full-length of virulence flagellin gene (flaB) was employed for rapid identification of Leptospira spp and of Leptospira-specific 16S rDNA (rrs) for differentiation from other bacteria. This approach distinguished pathogenic from non-pathogenic Leptospira strains, and the generation of restriction fragment length polymorphism profiles using a combination of restriction endonucleases allowed identification of pathogenic Leptospira species. PCR-based identification of Leptospira flaB provides an accurate and rapid tool for identification of leptospires and can be used as a means for rapidly identifying animal reservoirs responsible for leptospirosis outbreaks.
