This year, two veterinarians reported unusual cases of diarrhea and death in cattle, both initially presenting with bloody diarrhea, weakness, fever, and rapid mortality. Diagnostic lab analysis revealed Yersinia pseudotuberculosis as the cause, ruling out other common causes like salmonella and bovine viral diarrhea virus. Yersinia pseudotuberculosis, part of the same bacteria family as the bubonic plague-causing Yersinia pestis, typically causes gastroenteritis in humans. It is found in soil and various animal reservoirs and is more common in northern climates.

Cases in Saskatchewan and South Dakota showed similarities, with affected animals showing systemic disease symptoms and, in some instances, co-infections with giardia and coccidia. Stressors impacting the immune system, along with cool, wet conditions, appear to facilitate the infection. Early antimicrobial treatment proved effective for clinically affected animals. These cases highlight the importance of accurate diagnosis, as similar symptoms may require different management strategies.
