Abstract

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), streptomycin (46), tetracycline (46), triple-sulfonamide (12), chloramphenicol (1), nitrofuran (1), and neomycin (1). All isolates were resistant to at least 2 drugs, 8 were resistant to 4, and one to all 7.
