Haemorrhagic septicaemia in cattle and buffaloes*
نویسنده
چکیده
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 designated 6:B and 6:E have been found to cause HS.

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 ...

Study on Immunity of an Experimental Oil Adjuvant Haemorrhagic Septicaemia Vaccine in Cattle.
An oil adjuvant vaccine (OAV) was prepared from a local strain of Pasteurella multocida. Strain 6:B was cultured and inactivated by formalin. Bacterial pellet was prepared by centrifugation and subsequently adjuvanted by Montannide oil ISA-70. A dose of prepared vaccine containing 3ml (2mg dry weight/ml) was injected into five calves by IM route. Animals were bled before and at 24, 90, 150, and...
