Hemorrhagic Septicemia is a severe bacterial disease of cattle caused by Pasteurella multicoda. It is rapidly fatal. The disease is spread through contact with infected animals, contaminated clothing or equipment. Animals under stress or with poor body condition are believed to be more susceptible to P. multicoda infection.

Endemic Areas

Africa and Asia. The United States and Canada are considered free of Hemorrhagic Septicemia.

Clinical Signs

• Lethargy
• Reluctant to move
• Painful/difficult breathing
• Excessive salivation
• Swollen neck and lower jaw
• Fever
• Sudden death

Treatment

Death from Hemorrhagic Septicemia often occurs in 6 to 24 hours, making treatment with antibiotics virtually impossible. Any cow suspected of having Hemorrhagic Septicemia should be reported to the State Veterinarians or USDA Area Veterinarian in Charge immediately.

Prevention

Vaccination for Hemorrhagic Septicemia is available. Maintaining herds in good physical condition and barring the entry of animals of unknown health status will help prevent the introduction of Hemorrhagic Septicemia into a herd.

Public Health

There have been no reported cases of humans becoming infected with P. multicoda. However, humans are susceptible to other Pasteurella species, so appropriate precautions should be taken when handling infected animals.
