There is growing evidence that the microbiome influences host phenotypic variation. Incorporating information about the holobiont - the host and its microbiome - into genomic prediction models may accelerate genetic improvements in farmed animal populations. Importantly, these models must account for the indirect effects of the host genome on microbiome-mediated phenotypes.

Antimicrobial resistance (AMR) is a growing global health concern for both animal and public health, and collaborative strategies are needed to combat the threat. The level of awareness and funding for policies focused on reducing AMR varies between countries. The aim of this study was to compare the integrated surveillance systems for AMR in high and low-middle economies of the Asia-Pacific Economic Cooperation and determine whether there was any improvement from 2015 to 2018.

Chilean aquaculture mainly produces salmonids and molluscs. Salmonid production has been questioned by its excessive use of antimicrobials. This study aimed to investigate the bacterial microbiota composition of Mytilus spp.

Article Synopsis
  • Shiga toxin-producing Escherichia coli (STEC) is a harmful bacteria causing serious illnesses in humans, largely linked to food contamination, and has witnessed rising antimicrobial resistance in recent years.
  • A study in Chile analyzed STEC in various food samples (meat, seafood, vegetables, and street food), finding a small percentage (0.5%) positive for STEC, with specific virulence genes and predominant resistance to colistin.
  • The research identified various sequence types (STs) of STEC, including international clones usually found in human infections, marking the first comprehensive genomic examination of these strains in Chilean food sources.
