Three outbreaks of peracute to acute pneumonia in cattle of varying ages and breeds were investigated. Death losses were high, and often occurred within 12-24 hours of the onset of clinical signs of illness, in spite of aggressive antimicrobial treatment. Gross necropsy examinations consistently showed greater lung involvement (greater than 50%) than expected for the short course of the disease. In each case, the primary (or only) pathogen isolated was Bibersteinia trehalosi, a bacteria closely related to Mannheimia hemolytica, which has been commonly associated with acute disease in sheep and goats.
