THE IMPORTANCE OF RIBOTYPING OF PASTEURELLA-MULTOCIDA

Porcine isolates of Pasteurella multocida were characterised by phenot ypic and genotypic methods. Studies were performed before and after pi gs from different sources were mixed. Before purchase the protein and ribotype profiles were essentially unique. After up to one year after purchase more types were detected and after 2 years two protein and tw o ribotypes were detected. The findings of The study are discussed wit h respect to immunoprophylactic methods.
