A veterinarian (American English) or a veterinary surgeon (British English), often shortened to vet, is a doctor who treats animals and a practitioner of veterinary medicine. The word comes from the Latin veterinae meaning "working animals". "Veterinarian" was first used in print by Thomas Browne in 1646. Many careers are open to those with veterinary degrees (Doctor of Veterinary Medicine), D.V.M., VMD ( Veterinaria Medicina Doctoris), MVB (Medicina Veterinaria Baccalaureate), BVS (Bachelor of Veterinary Surgery), BVMS (Bachelor of Veterinary Medicine and Surgery), BVetMed (Bachelor of Veterinary Medicine) or B.V.Sc. & A. H. (Bachelor of Veterinary Science and Animal Husbandry). Those working in clinical settings often practice medicine in a limited field such as "companion animal" or pet medicine, which includes small animals such as dog, cat, and pocket pets, production medicine or livestock medicine. Production medicine includes specialties in dairy cattle, beef cattle, swine, sheep, and poultry, equine medicine (e.g., sport, race track, show, rodeo), laboratory animal medicine, reptile medicine, or ratite medicine. Veterinarians may choose to specialize in medical disciplines such as surgery, dermatology or internal medicine, after post-graduate training and certification.
Some veterinarians pursue post-graduate training and enter research careers and have contributed to advances in many human and veterinary medical fields, including pharmacology and epidemiology. Research veterinarians were the first to isolate oncoviruses, Salmonella species, Brucella species, and various other pathogenic agents. Veterinarians were in the forefront in the effort to suppress malaria and yellow fever in the United States. Veterinarians identified the botulism disease-causing agent, produced an anticoagulant used to treat human heart disease, and developed surgical techniques for humans, such as hip-joint replacement, limb and organ transplants.
