Abstract

SUMMARY: Dwarf colony variants of have been described as a causative agent of bovine mastitis in Israel. These strains were reported as auxotrophic for thiamine, being unable to synthesize the vitamin from its pyrimidine and thiazole moieties. In the present paper it is shown that strains with two different deficiencies are involved. One type is unable to concentrate the thiazole moiety and the other is unable to phosphorylate the pyrimidine portion of the vitamin. The results indicate the existence of independent permeases in for these thiamine moieties.
