Abstract

Previously identified strains of pasteurella multo cida types B,A,D and E were used for studying the Pathogenicity of each separate strain in sheep. The used strains were standar and some local strains isolated from sheep, cattle and dog. Pasteurella multocida type A strains were highly virulent to sheep and led to higher mortalities than other strains while type B produced no mortalities, however type D and E strains produced some mort alities.
