Immune response to an alum precipitated haemorrhagic septicaemia vaccine in buffaloes at a semiorganized farm of Madhya Pradesh in India

Haemorrhagic septicaemia (HS) is one of the economically most important bacterial diseases of large ruminants. In the present investigation, a total of 156 buffaloes (Murrah, Jafarabadi, and Bhadawari breeds) at a semiorganized farm after administration of HS alum precipitated killed vaccine were screened serologically for the presence of anti-HS antibodies by single dilution indirect enzyme linked immunosorbent assay (iELISA). Out of 156 buffaloes tested for presence of anti-HS antibodies, a greater proportion of buffalo (67.94%) had protective level of anti-HS antibodies even after 90th day post vaccination.
