Emerging viral infectious diseases are a major threat to the swine industry worldwide. Senecavirus A (SVA), an emerging disease that causes lesions around pigs' noses and hooves, affects herds around the globe. SCA has caused growing concern among producers, veterinarians, and researchers since 2015, due to the inability to distinguish an SVA infection from a foot-and-mouth disease virus infection. And preventive and diagnostic strategies lag behind, which presents a problem for all emerging infectious diseases.
Canine hemangiosarcoma is a relatively common cancer in dogs, found in the inner lining of blood vessels. Hemangiosarcoma spreads silently and painlessly, making it difficult to detect until it becomes very advanced, and therefore difficult to treat.
Roughly half the healthy racing thoroughbreds experience cardiac arrhythmias — or, irregular heartbeats — when exercising. Nineteen percent of horse deaths on the racetrack are considered sudden, but only 53 percent of those sudden death cases receive a diagnosis. Since cardiac arrhythmias are untraceable in deceased horses, Molly McCue, DVM, MS, PhD, DACVIM, and Sian Durward-Akhurst, BVMS, MS, PhD, DACVIM, hypothesize that these arrhythmias are the underlying cause of death for many of these horses with no visible cause of death.
In the swine industry, mother pigs are often replaced with female baby pig populations, known as gilts, to maintain genetic diversity and productivity. However, a consequence of introducing these young pigs is that they may carry disease, particularly a type of bacteria, known as Mycoplasma hyopneumoniae, one that causes contagious pneumonia. A team of researchers led by Maria Pieters, DVM, PhD, recently published a study that looked at the natural infection rate of M.
Antibiotics are critical for treating many infections, but resistance to these valuable drugs, known as antimicrobial resistance (AMR), threatens their effectiveness and introduces additional health issues.
