The immunogenicity and pathogenicity of Pasteurella multocida isolated from poultry in Namakkal

Abstract

Five field isolates of Pasteurella multocida from poultry in Namakkal, Tamil Nadu, India were serotyped as Heddeleston serotype 1 (three isolates) and Heddeleston type 1 with weak cross reactivity to 4 and 14 (two). The pathogenicity of one isolate has been studied and a killed vaccine was developed. The vaccine provided good homologous protection
