title: Production and standardization of polyvalent Clostridium perfringens vaccine in Iran.
abstract: In this presentation an account of the large-scale production and the standardization of polyvalent Clostridium perfringens vaccine in Iran is described. Over 20 million doses of this vaccine are produced and utilized in Iran every year. Certain modifications have been made to the culture media used in our laboratory for the production of this vaccine in order to bring down its cost. The prepared vaccine is highly immunogenic as determined by the laboratory examination on the quality of the vaccine according to British Veterinary Codex and the field reports.
