![]() The images show that the heart and one lung are stained with stomach contents that leaked along the penetrating wire. Hardware disease in beef cows is seen most often prior to calving when cows are being fed ground hay. A mixture of bacteria was identified from the uterus including Trueperella pyogenes and E. She was having some neurological signs shortly before death (a rabies test was negative). Trueperella pyogenes was identified.Ī dead adult cow was submitted after calving five days previously. There was severe bilateral pyelonephritis. ![]() One dead six-year-old cow submitted with history of weight loss. The infection most likely entered through the umbilicus. The liver contained multiple 1-2 cm areas of necrotizing hepatitis. No evidence of infectious disease or toxicosis was found. Exhaust fans may also have malfunctioned. In addition, the floor was heated and bedded. They went from an environmental temperature of -37F (-60F wind chill) to an indoor heated area where it was 70F. The cattle were fat and covered with a thick winter hair coat. Twenty five of 359 cattle were found dead the morning after being delivered to a packing plant for slaughter. Parasiticides are available to help control flukes, and clostridial bacterins containing Clostridium haemolyticum should be used when needed. Clostridium haemolyticum was isolated from the affected liver. A wedge shaped area of necrotic liver was observed. These heifers were pastured in an area of Minnesota known to have deer flukes. ![]() It had cardiomegaly and a 2.5 inch long high ventricular septal defect. This one month old beef calf was found dead. The death was caused by blood loss from a liver lobe torsion which then ruptured. Poor calving area hygiene was likely related to the problem. This calf had pus in the anterior chamber of the eye, a navel infection, arthritis, septicemia and meningitis. Twelve 3 to 4 day old dairy calves became blind and died one day later.

The hay was baled in a ditch to help winter the bison. The two bison in the image died in the fall from chronic disease. The herd experienced losses in the spring. This herd of bison was fed hay that contained chopped up cable. An isolate was sent to a private company for autogenous bacterin production. Streptococcus suis was identified from all locations. This nursery pig had pus in the anterior chamber of the eye, polyarthritis and meningitis. Visit often to see our changing caseload.
