feedlot cattle are respiratory disease, infection of the heart and TEME. It may also be part of the classical “shipping fever complex,” often showing up as a cause of severe fi brinous pleuritis and pericarditis. Other forms of this disease may show up as joint infection and infl ammation, causing lameness, or central ner- vous signs of disease (TEME). Diagnosis is diffi cult because of the diffi culty of
culturing at the laboratory. A complete necropsy should be performed upon death as soon as possible. As an example, a calf dead of central nervous dis-
order H. somni may have secondary signs of bloat. It is easy for even the experienced veterinarian or pa- thologist to miss the diagnosis unless the brain, heart and lungs are examined microscopically. The best time for prevention is at the cow-calf level.

Because it is a killed bacterial bacterin, it requires 2 vaccinations 2 to 3 weeks apart to have any chance of proper prevention. Some pathologists believe the vaccine in combination with either clostridials or vi- rals is not always effective. However, our experience shows it to be effective when used as a single-antigen vaccine in both the cow-calf and feedlot environment. H. somni is more of a cold weather disease and
is seen mostly in the fall when calves are coming into the feedlot. Even though many calves have the organism in their system, it doesn’t seem to show up clinically until the cold weather hits. It is susceptible to a wide variety of antibiotics, and
treatment decisions are made according to the veteri- narian’s experience with certain drugs. Tetracyclines may be used, as well as many of the newer, longer- acting antibiotics used to treat bovine pneumonia. Early recognition and treatment are very important to the success of response to this organism.
