Experimintal Study of Peracute Fowl Cholera due to Pasteurella multocida Vaccinal Strain (serotype A1) in Chickens
In order to show the type and severity of gross and histopathologic lesions induce by vaccinal strain (serotype A1) of Pateurella mulocida, ten four-week-old SPF chickens were inoculated intramuscularly with 75 cfu of ( 0.5 ml of 10-7 dilution) bacterium. All birds died in less than 16 hours. No prominent gross lesions were observed in different organs. In microscopic examination, the most comm...
متن کاملEvaluation of immunogenicity and protective efficacy of recombinant ptfA of avian Pasteurella multocida
Avian Pasteurella multocida is the causative agent of fowl cholera, a disease much affecting the poultry industry. In order to study the efficacy of the recombinant subunit vaccine constructed with ptfA gene of avian P. multocida, the ptfA gene fragment amplified by PCR from avian P. multocida was cloned into the prokaryotic expression vector pET32a and the recombinant plasmid pET32a-ptfA was o...

متن کاملEvaluation of a Trivalent Pasteurella multocida Vaccine Consisted of Serotypes 1, 3 and 4.
An inactivated trivalent fowl cholera vaccine consisted of serotypes 1, 3 and 4 Pasteurella multocida strains was prepared. The vaccine provided 70-100% protection against challenge with homologous starins. ELISA assay showed a considerable increase in antibody titer after towice vaccination of 8 weeks chickens. It was found that the trivalent vaccine can induce immunogenic response in vaccinat...
متن کاملProtection against fowl cholera conferred by vaccination with recombinant Pasteurella multocida filamentous hemagglutinin peptides.
Three gene fragments, derived from Pasteurella multocida strain P-1059 (serotype A:3), encoding approximately the 5' one-third of fhaB2 were overexpressed individually in Escherichia coli. The recombinant peptides were purified, pooled, and administered to turkey poults to evaluate immunity. The results showed that turkeys immunized twice with the recombinant peptides were significantly protect...
