Custom Biologicals

Texas Vet Lab (TVL) has been conducting research, development, diagnostics, and producing USDA fully-licensed commercial vaccines since 1982 with the primary focus being on the pathogens that cause Bovine Respiratory Disease in stocker/feeder cattle.
Commercial vaccine production is primarily bacterins and bacterin-toxoids that contain the following organisms in specific combinations:
  • Mannheimia haemolytica Types A-1 and A-6
  • Pasteurella multocida
  • Histophilus somni
  • Salmonella typhimurium
  • Mycoplasma bovis
Additionally, TVL also manufactures a combination Mannheimia, Pasteurella, Histophilus bacterin-toxoid that contains killed IBR and killed BVD-1a.  Also, a compliment to this product is our adjuvanted, modified live virus vaccine that containing IBR, PI3 and BRSV that confers protection after a single dose.
TVL has been licensed to manufacture autogenous (custom) biologicals for over 20 years.  Previous management practice was to reserve the use of autogenous vaccines for disease-causing organisms of which a fully-licensed commercial vaccine was not available, a need for improved antigen specificity, or other scientific justification demonstrating a need for a more efficacious vaccine. Some examples of these vaccines are:
  • ·Moraxella ovis for cattle
  • ·Corynebacterium pseudotuberculosis for goats
  • ·Unique serotypes of M. haemolytica for cattle, sheep and goats
  • ·Unique serovars of Salmonella for cattle
  • ·Unique isolates of Mycoplasma bovis
