Isolation and Characterization of Pasteurella multocida from Poultry and Deer

Isolation of P. multocida was attempted from samples obtained from the poultry and deer, using standard bacteriological procedures for a period of 2 years. Ten isolates were obtained from 155 samples. All the isolates were found to be pathogenic for mice. Based on variations in fermentation patterns of dulcitol, mannitol, sorbitol and trehalose, the 10 isolates were grouped into biovars. All isolates have been serotyped as A:1. Two biotypes viz, P. multocida subsp. gallicida and P. multocida subsp. multocida were observed among the isolates examined. In the antibiogram of P. multocida isolates, all of them were uniformly sensitive to nitrofurantoin and chloramphenicol. The isolates DP36 and DP40 were resistant to gentamicin whereas all other isolates were sentive to it. Only DP39, DP40 were sensitive to sulphadiazene.
