Dear Colleagues,

The use of antimicrobials in the veterinary sector has significantly decreased morbi-mortality and increased performance in this sector. Unfortunately, this intensive and uncontrolled use has led to the appearance and generalization of multidrug-resistant bacteria in animals, causing considerable losses to animal breeders. Furthermore, it has been shown that animals serve as reservoirs of antimicrobial-resistant bacteria and as vehicles for further dissemination to humans. Therefore, investigation of antimicrobial use and resistance in the veterinary sector is important to combat zoonotic antimicrobial resistance and significantly reduce the occurrence of human infections caused by microbes of animal origin.

In this collection, original research articles and reviews focusing on antimicrobial use and resistance in animals are welcome. Original research articles and reviews can cover key topics, such as consumption of antimicrobials in veterinary sector, in vitro and in vivo antimicrobial activity assessments, prevalence of antimicrobial-resistant zoonotic bacteria, antimicrobial resistance genes, mobile genetic elements carrying antimicrobial resistance genes, methods used to investigate zoonotic antimicrobial resistance, and the transmission of antimicrobial-resistant bacteria from animals to humans.
