Haemorrhagic Septicaemia HS


The disease is caused by Pasturella multocida type-I organism. It is a gram negative coccoid, short rod organism. The organism were typed as Robert’s type-I, type-II, and type-IV.T

Susceptible Hosts

Cattle and Buffaloes are the most susceptible species. Young growing cattle and buffaloes within the age group of month to 2 years are most often affected. Sheep, goat, and pig may also suffer.

Mode of Transmission

  • The disease is transmitted through contact with the infected animals.
  • Carrier animals may harbour the infective organism in their nasopharynx and thus help in spreading the disease in susceptible population through droplets inhalation or ingestion. 
  • Through droplets inhalation or ingestion of sick animals.
  • Through infected utensils, water, and attendants.

Clinical Symptoms

Septicaemic pasturellosis flares up as an outbreak during the environmental stress.The organism which remains in the tonsilles and nasopharyngeal mucosae assume the pathogenic role and there by set up clinical disease. The incubation period is 2 – 5 days. There is high rise in temperature 104 – 107 F with concurrent shivering followed by profuse salivation, lacrymation and nasal discharge. The affected animal exibit sign of abdominal pain,sever diarrhea. Rapid respiration. In less acute cases, there is rise in body temperature and localization of oedema in subcutaneous pockets of the head, neck, duwlop and brisket region. The oedema produce sever dyspnoea due to obstruction of respiratory passage. Death usually occur within 20-24 hours.



The effective control lies with institution of adequate management, rational execution of vaccines and care in transportation of animal.

  • An effective prophylactic vaccination of all susceptible animals of the enzootic areas should be made.
  • Extreme stress on animals should be avoided.
  • In hot and humid season a comfortable environment should be provided to the animals.
