Disease
Six states have reported new HPAI cases in dairy cattle over the past 30 days, bringing the total to 22 states since the virus was first detected in dairy cattle in March 2024.
Nineteen cattle developed a severe, unexplained disease across multiple farms. Investigators found a common thread in their feed, but couldn’t identify what triggered the outbreak.
Five years of diagnostic surveillance reveal age-related and seasonal patterns in bovine coronavirus detection, alongside continued genetic variation.
Washington has seen a spike in HPAI cases in dairy herds in recent weeks, with Texas and Kansas also reporting cases in the past 30 days and a human case confirmed in a Washington dairy employee.
From analyzing cattle muzzles to recognizing eye changes, artificial intelligence is showing promise as a tool for detecting and monitoring infectious bovine keratoconjunctivitis.
At least nine horses have been confirmed with the bacterial disease in 2026. Veterinarians should watch for abscesses, reinforce fly control and follow biosecurity precautions.
Young pasture-raised heifers developed mild hoof lesions, prompting testing that identified EHD virus.
Traceability and expanded surveillance are driving Namibia’s response as officials work to demonstrate the outbreak has remained localized.
A redesigned adjuvant may be able to help an injectable BVDV vaccine stimulate both systemic and intestinal immune responses.
For Dr. Brad White, investigating bovine heart disease means looking beyond the heart to understand what is happening throughout the animal.
Two distinct variants and evidence of fetal infection are adding new questions to an outbreak first identified in European cattle this summer.
Cattle can carry and shed Leptospira without showing signs of disease, raising questions about how much leptospirosis is going undetected.
The approach could offer a new way to identify MAP infection by detecting changes in the cow’s blood rather than the pathogen itself.
When evidence falls short, veterinarians and producers rely on experience, collaboration and careful judgment to manage the complex realities of tick-borne disease.
Infectious bovine keratoconjunctivitis may be more complex than a single bacterial infection, opening new avenues for prevention and vaccine development.
A new study has found Bovine Leukemia Virus DNA in biting insects, adding evidence for a possible role in the virus’ transmission.
New Missouri-based research offers insight into how bovine anaplasmosis spreads naturally and why infected ticks have remained so difficult to detect.
Bovine tuberculosis control changes dramatically depending on where the disease survives. Canada’s recent investigations have focused on tracing rare infections through cattle movements, while Michigan’s long-running battle centers on managing the disease in white-tailed deer.
From vaccinations to diagnostics, misconceptions about BVD can leave costly gaps in herd health programs. Veterinarians Dr. Robert Larson and Dr. Christopher Chase help separate fact from fiction on one of the cattle industry’s most economically important diseases.
After nearly 14 years without foot-and-mouth disease, Europe faced multiple unrelated incursions in 2025 and 2026. Rapid detection, regionalization and vaccine readiness helped contain the virus and offered lessons for animal health professionals worldwide.
Many calves develop pneumonia days before showing symptoms. Lung ultrasounds are helping veterinarians detect the hidden disease earlier.
The affected herd is located in Charlevoix County, located west of Michigan’s Modified Accredited Zone (MAZ), where the disease is known to be present in the state’s white-tailed deer population. The detection follows identification of bovine TB in an adult cow at a USDA Food Safety Inspection Service-inspected processing plant.
Researchers are beginning to step back and look at the bigger picture, examining how the virus affects cows not only in the days and weeks after infection, but what it may mean for their health and performance long after.
Treatment timing is not a single choice, but a moving target, that must balance sensitivity, percision and group-level signals to intervene effectively.
By mapping where EHV persists during latency, researchers hope to improve understanding of reactivation and disease spread.
California has lifted its HPAI-related ban on poultry and dairy cattle exhibitions, allowing shows to return to fairgrounds after more than a year.
A model developed by the Western Institute for Food Safety and Security at UC Davis shows how disease spread affects milk production and recovery timelines on a closed dairy.
