Veterinary technologists play an important role in the maintenance of animal health and productivity. Their tasks consist of diagnostic work to determine the cause of sickness or death of an animal. They also carry out technical and field studies in research where they work with a professional team of researchers, veterinary surgeons, other experts and scientists.
Veterinary technologists are employed in the production of biological products such as antigens for diagnostic tests and vaccines for the prevention of disease. In a research or diagnostic laboratory, veterinary technologists who are specifically trained to execute laboratory procedures, handle and inject animals, draw blood and take other samples to assist the veterinarian and other scientists trained in the fields of Microbiology, Parasitology, Chemistry, Biochemistry and Animal Science.
They must continually make the necessary observations and record such observations. Veterinary technologists and nurses always work with or under the supervision of veterinary surgeons. Technologists are now able to take the initiative to run a private diagnostic or other laboratory, if they are trained in that specific field.
The work of veterinary technologists can primarily be divided into three categories:
Diagnostic work, where specimens of animal tissue such as blood and organs, plants and feeds are subjected to a variety of tests to determine the cause of disease or death.
Research, which is mainly problem-orientated and embraces studies on the causes of animal diseases, the methods of transmission, the specific effects on normal physiological processes and the most effective ways of preventing or combating the diseases in animals. These studies are performed under the guidance and direction of professional scientists and veterinary surgeons.
Preparation of veterinary biological products, such as antigens for diagnostic tests and vaccines for the prevention of disease, is largely the task of veterinary technologists. This involves large-scale cultivation of bacteria and viruses and a considerable amount of developmental work, particularly in the field of fermenter technology.
Veterinary technologists work in clean, orderly, well-equipped laboratories with only the best scientific apparatus at their disposal. Some tasks involving the handling of animals may take place out-of-doors in the open fields.
