Pathogenicity and immunogenicity of native and mutant strains of Pasteurella multocida, the causative agents of haemorrhagic septicaemia
Haemorrhagic septicaemia (HS) is a fatal systemic disease of cattle and buffaloes. Some control isachieved with administration of alum-precipitated or oil-adjuvanted killed whole-cell vaccines injectedsubcutaneously. These vaccines, however, provide only short-term immunity and for effective use, theyshould be administered annually. We constructed an aroA attenuated derivative of a Pasteurella ...
متن کاملHaemorrhagic septicaemia in cattle and buffaloes*
Haemorrhagic septicaemia (HS) is a highly fatal disease in cattle and buffaloes, caused by specific serotypes of Pasteurella mul tocida. It is a primary pasteurellosis reproducible in susceptible animals with the specific organism alone. The accepted classification of Pasteurella multocida is based on the identification of its somatic and capsu lar antigens. On this basis two serotypes designa...
متن کاملMolecular diagnosis of Haemorrhagic Septicaemia - A Review
Pasteurella multocida is associated with hemorrhagic septicaemia in cattle and buffaloes, pneumonic pasteurellosis in sheep and goats, fowl cholera in poultry, atrophic rhinitis in pigs and snuffles in rabbits. Haemorrhagic septicaemia is caused by Pasteurella multocida type B:2, B:2,5 and B:5 in Asian countries and type E:2 in African countries. Pasteurella multocida have five types of capsula...
متن کاملIsolation, Molecular Characterization and Antibiotic Susceptibility Pattern of Pasteurella multocida Isolated from Cattle and Buffalo from Ahwaz, Iran
Pasteurella multocida is a gram-negative, opportunistic pathogen and the common inhabitant of the upper respiratory tract of domesticated and wild animal species. It is a causative agent of numerous economically important diseases worldwide, such as enzootic bronchopneumonia in ruminants and haemorrhagic septicemia in cattle and buffalo. The present study was undertaken to determine the prevale...
متن کاملGenetic diversity among Pasteurella multocida strains of avian, bovine, ovine and porcine origin from England and Wales by comparative sequence analysis of the 16S rRNA gene.
Genetic diversity among 86 Pasteurella multocida isolates was investigated by comparative sequence analysis of a 1468 bp fragment of the 16S rRNA gene. The strains included 79 field isolates recovered from birds (poultry) (22), cattle (21), pigs (26) and sheep (10) within England and Wales, four Asian isolates associated with bovine haemorrhagic septicaemia, and the type strains of the three su...
