P. haemolytica was isolated from 51 of 65 nasal swabs taken from cattle with untreated respiratory disease in Kentucky in 1978 (23 of 29 cattle), 1979 (18 of 22), and 1980 (10 of 14). Isolates were resistant (in vitro) to ampicillin (21 isolates), st

Salmonellosis represents the most prevalent zoonotic infection of Bovidae. Approximately 111 of the over 1700 salmonellae serotypes have been found in cattle (1). Eighty-one types of Salmonella have been cultured from cattle in the U.S. (1). It may b

Three hundred and forty-two heifer calves were assigned to three treatments; (1) 30 calves exposed to IBR/IPV virus (2) vaccinated against IBR/IPV virus and bovine diarrhoea virus and (3) non vaccinated controls. Treatment groups were housed in separ

Experiments were conducted using a 3 by 2 factorial design to evaluate the efficacy of Haemophilus somnus and unspecified Pasteurella inactivated vaccines and to compare the oral and intramuscular route of administration of a BVD vaccine. 303 crossbr

The role of bacteria in the production of acute bovine respiratory disease (BRD) (shipping fever) has long been recognized. Although numerous bacteria have been isolated from the respiratory tracts of affected cattle, Pasteurella sp. have been consid

It has been suggested that the deworming dose of levamisole administered at the time of processing cattle into the feedlot could be immunostimulatory and result in a reduced incidence of respiratory disease. This controlled field trial was undertaken

Oxytetracycline had been widely used at 11 mg/kg for the treatment of respiratory disease in feedlot cattle. The increased prevalence of resistant strains of Pasteurella sp. has resulted in recommendations for increasing the dose to 33 mg/kg or as mu

The antibiotic used first in beef cattle with respiratory disease (attributable to Pasteurella haemolytica) was erythromycin. The cure rate fell from 60% in 1984 to 53% in 1985. Cases which failed to respond were next treated with amoxicillin, giving
