Bovine Vaccines

Pasteurella vaccines for the control of pneumonia

Pneumonia in cattle caused by Pasteurella multocida and Mannheimia (formerly Pasteurella) haemolytica may become chronic and prove difficult to control with antibiotics. Mass-produced vaccines are available for controlling these types of infection, however if the infecting strains are atypical, such vaccines may prove ineffective. We have produced mono- and poly-valent vaccines that have proved highly effective in controlling and preventing bovine pneumonia caused by these pathogens.

Digital Dermatitis vaccines

Dichelobacter nodosus and Fusobacterium necrophorum are the most common causes of digital dermatitis (foot rot) in cattle in the U.K. No mass-produced foot rot vaccine based on these organisms is currently licenced for use in cattle in the U.K. We are able to produce site specific emergency vaccines based on Dichelobacter nodosus and/or Fusobacterium necrophorum, depending on which organisms we are able to isolate from infected animals.

Mastitis vaccines

The failure of existing control measures to control mastitis in the UK dairy herds has emphasized the need to develop alternative control strategies. A range of bacterial pathogens are associated with acute and chronic forms of mastitis. The classical contagious pathogens include Staphylococcus aureus, Streptococcus agalactaiae and Streptococccus dysgalactiae. Environmental pathogens include Streptococcus uberis, E.coli and Klebsiella pneumoniae. Outbreaks of mastitis are often associated with more than one pathogen on any one site. We are able to produce mono- or multi-valent vaccines formulated specifically to control the pathogens prevalent in a particular herd.
