MADRAS VETERINARY COLLEGE

DEPARTMENT OF VETERINARY PARASITOLOGY


Genesis

The Department of Veterinary Parasitology was started in 1929. During the year 1947, this department was recognised as a postgraduate department for the award of M.Sc., degree. During 1955-58, three batches of ICAR sponsored postgraduate course leading to 'Diploma in Veterinary Parasitology' was conducted and 15 candidates from various states underwent the diploma course. In 1958, this department was upgraded as postgraduate department for the award of M.V.Sc., degree and in 1960 it was recognized for Ph.D., programme. The Helminthology museum in this department contains a very large collection of worms from domestic animals and birds identified and classified systematically, which forms a very useful source of reference for research workers.

Objectives

  • To offer courses in Veterinary Parasitology for undergraduate and postgraduate students and to introduce innovative educational technologies in teaching and evaluation for U.G. and P.G. students.
  • To undertake research on parasitic diseases for rapid diagnosis and effective control
  • To disseminate the advances in diagnosis and control of parasitic diseases/infections by offering training programmes and contact courses to field veterinarians
  • To create awareness on parasitic infections in livestock and pets and the need to control them to entrepreneurs, farmers and pet owners through TV, All India Radio, popular articles, pamphlets and books.
