Effects of 5-Fluorouracil and 5-Fluorodeoxyuridine on Growth and Tumor-Inducing Ability of Agrobacterium tumefaciens.

Beardsley, Robert E. (Manhattan College, Bronx, N.Y.), and Jacques Lipetz Effects of 5-fluorouracil and 5-fluorodeoxyuridine on growth and tumor-inducing ability of Agrobacterium tumefaciens. J. Bacteriol. 92:346-348. 1966.-Agrobacterium tumefaciens B6, grown in the presence of 5-fluorouracil or 5-fluodeoxyuridine, exhibited a prolonged lag phase. The tumor-inducing ability of bacteria grown in the presence of these compounds was decreased even after exposures as short as 40 min. A positive correlation was found between the growth-inhibitory effects of these compounds and their effects on the tumor-inducing ability of the bacteria.
