A recent pilot study established processes for voluntary data sharing on how swine producers use antibiotics. Peter Davies, BVSc, PhD, led the study, which set out to advance knowledge of antimicrobial use in the U.S. swine production herds and to support antimicrobial stewardship across that industry. The study identified variation in antimicrobial use among nine large U.S. swine agriculture systems — which together produce more than 20 million pigs each year — in 2016 and 2017.

Released during the 2020 U.S. Antibiotic Awareness Week, this Zoonoses and Public Health publication highlights collaboration among academics, the FDA Center for Veterinary Medicine, and U.S. food animal industries.

A recent study is among the first to identify genes that may lead to immune-mediated hemolytic anemia (IMHA), a life-threatening autoimmune disorder. IMHA results in the immune system attacking circulating red blood cells, inhibiting their ability to deliver oxygen around the body. The disease also causes blood clots, which can be lethal as well. IMHA occurs naturally in both dogs and humans but is more prevalent in dogs, and scientists are still searching for the disease’s root cause. Dogs offer a naturally-occurring model for advancing the outcomes of human patients with IMHA.

While honey bees get Deformed wing virus (DWV) from a parasitic mite, Varroa destructor, the presence of the parasite is not a likely factor in increasing the spread of the disease for other insects, according to a recent study. Varroa destructor has spread DWV to honey bee colonies around the globe, contributing to large-scale colony loss for beekeepers. DWV can be found in many species of insects and spills from honey bees into both closely-related and other insects.

Researchers from the College of Veterinary Medicine and School of Public Health will investigate how detecting asymptomatic disease can reduce spread.
