Vaccinating against Clostridia and Pasteurella

Solution name: Vaccinating against Clostridia and Pasteurella

Aim: To present the benefits of vaccination against Clostridia and Pasteurella


    • Clostridia and Pasteurella are two families of bacteria that can cause major problems to sheep flocks
    • Pulpy kidney, black disease, braxy, lamb dysentery, struck, blackleg, tetanus, bacterial red water, haemorrhagic enteritis, enterotoxaemia, Clostridial metritis, malignant oedema, and Pasteurella pneumonia are diseases that can be vaccinated against
    • Most of these diseases do not cause detectable illness/symptoms other than death and outbreaks can occur

      How to implement:

      • By vaccinating ewes annually before lambing, their antibody levels remain sufficiently high to allow protective cover to be transferred to their lambs
      • For lambs to benefit from their dam’s vaccination, they must receive adequate quantities of good quality colostrum within the first 2 hours after birth to receive passive immunity
      • Animals should not be vaccinated if sick or immunodeficient
      • Vaccine type (Clostridial +/- Pasteurella) depends on individual farm issues
      • Vaccine should be stored as directed and shelf life before and after opening observed
      • Vaccination procedure can vary but it is typically administered by subcutaneous injection in the lateral side of the upper neck
      • The bottle should be well shaken before any vaccine is withdrawn
      • Syringes and needles should be sterile before use and the injection should be made through an area of clean, dry skin taking precautions against contamination

      A typical schedule for both Clostridial and Pasteurella vaccination in sheep is presented in the table below.
