| Abstract |
|
The present study was conducted to investigate the incidence of Pasteurella multocida infection in Youngnam swine herds during the period from March 1988 to February 1989 and some properties of the isolated organisms. P multocida was isolated from 22(43.1%) of 51 growing pigs of 4 to 12 weeks of age and from 8(80.0%) of 10 herds. From nasal turbinates of 102 slaughtered pigs, 47(46.1%) pigs were culture positive and pigs from 8(88.9%) of 9 herds were found to be infected with P multocida. From lungs of 101 slaughtered pigs, 42(41.6%) pigs were culture positive and the pigs from 11(91.7%) of 12 herds were found to be infected with P multocida. The majority of biochemical and cultural properties of the P multocida isolates were identical to those of the standard strains. The isolation frequencies of P multocida in relation to pig snout lesion grades of 0 to 5 were 28.6%, 41.6%, 48.0%, 50.0%, 85.7%, and 100%, respectively. |
