| Abstract |
|
The present study was conducted to investigate biochemical properties and antimicrobial drug susceptibilities of 57 strains of Pasteurella haemolytica (P haemolytica) isolated from pneumonic calves and goats in Youngnam province during the period from September 1989 to February 1991. P haemolytica was isolated from 95 of 142(31.7%) pneumonic calves of 1 to 6 months of age and from 9 of 24(37.5%) pneumonic goats of 2 to 10 months of age. Seasonal isolation frequency of P haemolytica in calves and goats varied from 16.6 to 35.7%, and it was higher in winter. The majority of biochemical and cultural properties of P haemolytica isolated from calves and goats were identical to those of the reference strains employed. All isolates were susceptible to ceftiofur, erythromycin, kanamycin, gentamicin, and chloramphenicol (MIC: <$25{mu}g/ml$), some of them were resistant to amikacin, sulfadimethoxin, and streptomycin (MIC: >200IU or ${mu}g/ml$). |
