Pasteurella Vaccines
By Dr Mackie Hobson BSc(Agric),BVSc

1. Vaccines

Good farm management includes management of the variables (predisposing factors) that the mohair producer has control over particularly with regards to minimising stress.

See the article on the website on Pneumonia

 https://www.angoras.co.za/page/pasteurella#36

For the other factors the producer has no control over Vaccination forms an important part of risk management.

Theoretically a COMPLETE Pneumonia vaccine would have to include antigens against all pathogens, viruses and bacteria, which play a role on Pneumonia. Such a vaccine simply does not currently exist.

TYPES OF VACCINES:

The dominant serotypes of Manneheimia haemolytica diagnosed in sheep with pneumonia have been 6,2,1 (in that order).

Mannehaimia haemolytica has also been the main cause of pneumonia in Angora goats when cultured (not typed). Pasteurella multocida is not considered important in Angora goats.

Vaccines licensed for use in goats are:

• OBP Pasteurella (OBP)
• Ovi-Clos P (Ascendis)
• Ovipast (Ceva)

Vaccines licensed for goats: Ovipast (Ceva) Ovi-Clos-P (Ascendis) and OBP Pasteurella (OBP)

Not licensed for goats (used off label)

• One Shot Ultra (Zoetis)
• Multivax -P Plus, Multivax-P (MSD)

Cross protection: Manneheimia haemolytica type A1 affords cross-protection against the type A2 and A6 strains.  Type A2 is a common complication in Pneumonia and Mastitis in sheep and goats.
