Veterinary parasitologists investigate internal and external parasites, conduct diagnostic examinations, develop control programmes, and support disease surveillance efforts. They analyse faecal samples, study parasite life cycles, assess drug resistance, and advise on farm and pet-care parasite prevention. Their work supports livestock productivity, pet health, and One Health initiatives addressing zoonotic parasites. They collaborate with research labs, government agencies, diagnostic centres, and veterinary drug companies. With rising parasite resistance and vector-borne diseases, this speciality is increasingly vital.
