Mammary glands of production animals can harbor avian flu: Iowa State study

An ongoing outbreak of highly pathogenic avian influenza has affected more than 184 million domestic poultry since 2022 and, since making the leap to dairy cattle in spring 2024, more than 1,000 milking cow herds. Iowa State University researchers report that the mammary glands of several other production animals – including pigs, sheep, goats, beef cattle and alpacas – are biologically suitable to harbor avian influenza due to sialic acids.

CVS Group (Australia) study identifies reliable predictor for canine tumors

A study from veterinary network CVS provided insights into how veterinary professionals can better predict outcomes for dogs with mast cell tumors. Researchers found that c-kit mutation in exon 11 and AgNOR may be more clinically useful than previously thought, and Ki67 less so. The study found that cutaneous and subcutaneous mast cell tumors behaved similarly in terms of survival and recurrence, suggesting they can be managed similarly.
