title: Larvicidal activity of actinomycete isolate against Toxocara canis.
abstract: A soil isolate of actinomycete, strain S-70, revealing presence of plasmid(s) was placed in the genus Streptomyces according to the wall composition and morphology. The toxicity of S-70 grown on two fermentation media, glucose-asparagine broth (GAB) and malt extract-yeast extract broth (MYE), against infective larvae of Toxocara canis was assessed. The use of mortality test has provided a sensitive and reproducible bioassay. The results suggest high larvicidal activity of the Streptomyces crude products examined being highly potent when using GAB culture medium.
