Information on Haemorrhagic Septicaemia (HS) in bovines (1995–98) was obtained from 237 veterinary surgeons working in all ninteen districts of Haryana through a questionnaire and analysed using student's ‘t’ test and Pearson's multiple correlation. Besides, eleven HS outbreaks were also investigated during 1998–99. The prevalence of HS in buffaloes and cattle was low (0.31 and 0.25%, respectively), but case fatality rate (CFR) was high (58.90 and 38.94%, respectively). The CFR was significantly (P<0.01) higher in young buffaloes than young cattle. The four years data revealed an increasing trend of HS outbreaks. The HS was found to be positively correlated with high rainfall, humidity and low temperature. Foot and mouth disease (FMD) was a common preceding infection in many HS outbreaks. Pasteurella multocida B:2 organisms were isolated from all the eleven outbreaks investigated. Antibiogram pattern revealed that majority of organisms were sensitive to enrofloxacin, gentamicin and chloramphenicol and resistant to sulphadimidine and oxytetracycline. Annual economic loss due to HS in buffaloes in Haryana was estimated around Rs. 58 millions.
