The campaign to eliminate which pathogen was a major incentive for establishing veterinary services worldwide?

• A. M. bovis
• B. Streptococcus agalactiae
• C. Brucella abortus
• D. Listeria monocytogenes

Answer: (A)

Focusing on how large-scale disease eradication shapes veterinary services helps connect the dots. The campaign to eliminate Mycobacterium bovis, which causes bovine tuberculosis, created a powerful incentive to build organized veterinary public health systems worldwide. Eradicating this pathogen required nationwide herd testing, rigorous movement controls, traceability, culling of infected animals, and coordinated reporting and outbreak response. To carry out these measures, governments needed trained veterinary professionals, diagnostic laboratories, and public health infrastructure that could oversee animal health and connect it to human health, especially since milk can transmit the infection to people. That combination of surveillance, regulation, and milk-safety needs drove the expansion of veterinary services on a global scale.

While campaigns against other pathogens like Brucella abortus and issues around mastitis or Listeria are important for animal and food safety, the global push that most substantially spurred the establishment of veterinary services worldwide was the effort to eradicate bovine tuberculosis caused by M. bovis.
