In sheep, it may be referred to as enzootic abortion, not associated with venereal transmission as much as ingestion of contaminated water and feed. Typically, the disease causes female infertility, with an increased number […] Read more

No one in […] Read more

Vet Advice: New regs to preserve old and new drugs

By
I’m often asked why even older antimicrobials are still considered medically important to human medicine. The premise, right or wrong, is to preserve antibiotic effectiveness by reducing the risk of antimicrobial resistance attributed to wholesale use in animal agriculture. While debate still rages over the impact new legislation will have on preserving antimicrobial effectiveness in […] Read more

Ergot poisoning: An ancient scourge remains a problem in modern rations

Vet Advice with Dr. Ron Clarke

The negative impacts of ergot contamination in food were recognized as early as the fifth century AD.

Fighting AMR: A true test of human resilience

By
The ongoing explosion of antimicrobial-resistant infections continues to plague global health care. Our inability to mount significant countermeasures to resistance, while at the same time enduring the decline in research and development of new antibiotics creates a “perfect storm” and the fear we may be on final approach to a pre-antibiotic era of serious and […] Read more

Vet Advice: Exploring the ‘hygiene hypothesis’

By
As a veterinarian, I wondered for many years if animals and humans could function normally in an environment free of pathogens, free of stress and devoid of all things considered harmful.
