Antibiotic use in aquaculture has become very controversial vis-à-vis driving antimicrobial resistance (AMR) in aquatic bacterial populations. The AMR trends in fish pathogens in Hong Kong over a four-year period suggests that providing small stakeholder farmers with free veterinary advice on fish health issues and treatments, as well as subsidized quality-assured medicines, likely reduced AMR. We observed a dramatic reduction in the proportion of bacteria resistant to oxolinic acid, oxytetracycline, and florfenicol on local aquaculture farms between 2018 and 2021.

- Leptospirosis is a zoonotic disease significant to swine, and a survey was conducted in HKSAR, China, from January to October 2020 to assess its prevalence in farmed pigs.
- Serum and kidney samples were taken from 105 swine across multiple farms, and testing methods like microscopic agglutination tests and PCR showed no signs of infection.
- Statistical analysis concluded that the prevalence of leptospirosis in farmed swine in HKSAR is likely less than 3%, indicating it is currently negligible in this population.
Ovine footrot is a major disease affecting sheep welfare and production. The anaerobic Gram-negative bacterium Dichelobacter nodosus is the essential transmitting agent. Monovalent or bivalent vaccines induce high levels of D.
