Demonstration of cross-protection between Pasteurella multocida type A and Pasteurella haemolytica, serotype 1.
Mice immunized with the potassium thiocyanate extract of Pasteurella haemolytica, serotype 1, were found to resist a challenge infection of P. multocida type A, thus demonstrating cross-protection. This finding was further supported by the finding that an antiserum directed against the potassium thiocyanate extract of P. haemolytica was bactericidal to P. multocida and vice versa.
متن کاملIdentification of Pasteurella multocida and Pasteurella haemolytica by API 20E, Minitek, and Oxi/Ferm systems.
Fifty serotyped isolates each of Pasteurella multocida and Pasteurella haemolytica were tested on the API 20E strip (Analytab Products, Plainview, N.Y.), the Oxi/Ferm tube (Roche Diagnostics, Nutley, N.J.), and the Minitek system (BBL Microbiology Systems, Cockeysville, Md.). None of the rapid test systems reliable identified these organisms. With the API system, discrepancies between expected ...
متن کاملLack of cross-immunity among Pasteurella multocida type A strains.
Active and passive protection studies in mice using sheep antisera revealed that the immunological relationship among Pasteurella multocida Type A strains could not be correlated with their serological relationship as determined by a haemagglutination or an agglutination test. Furthermore, strains possessing similar phenol extractable antigens or heat stable antigens did not provide complete cr...
متن کاملCloning of a serotype-specific antigen from Pasteurella haemolytica A1.
Recombinant plasmids coding for a soluble (or surface) antigen of Pasteurella haemolytica A1 were identified. Two plasmids, both containing the same 5.4 kilobase pairs of insert DNA, were recovered independently by screening a clone band of P. haemolytica A1 genomic DNA in Escherichia coli for the expression of P. haemolytica A1 soluble antigens (R. Y. C. Lo and L.A. Cameron, Can. J. Biochem. C...
متن کاملPathogenomics of Pasteurella multocida.
The first complete genome sequence of the P. multocida avian isolate Pm70 was reported in 2001. Analysis of the genome identified many predicted virulence genes, including two encoding homologues of the Bordetella pertussis filamentous haemagluttinins, and genes involved in iron transport and metabolism. Availability of the genome sequence allowed for a range of whole-genome trans...
