CO2 requirements and nucleic acid synthesis by Brucella abortus.
C1402 is fixed in pyrimidines of nucleic acids by Brucella abortus, strain 6232, during growth on complex artificial media (Newton et al., 1954). The incorporation of C02 into pyrimidines appears to be more obligatory in this strain of B. abortus which requires an increased pCO2 than it is in Escherichia coli (Bolton et al., 1952); a finding which suggested that strains of B. abortus which requ...
متن کاملPantothenic acid synthesis by smooth Brucella abortus.
The relationship between formation of exogenous alanine and the establishment of nonsmooth variants in originally smooth cultures of Brucella abortus strains has been clearly demonstrated (Goodlow et al., 1950). Furthermore, the addition of D-alanine to smooth cultures in synthetic medium (Gerhardt and Wilson, 1948) results in earlier establishment of nonsmooth cells (Goodlow et al., 1951). Sub...
متن کاملAlanine synthesis and carbohydrate oxidation by smooth Brucella abortus.
Although the metabolism of many bacterial species has been studied intensively, adequate knowledge of the metabolic activity of pathogenic organisms, including Brucella, is lacking. The biochemistry d physiology of Bruce>a recently have been summarized by Hoyer (1950). Goodlow et al. (1950) have demonstrated a direct correlation between alanine production and the establishment of nonsmooth vari...
متن کاملThe oxidation of glutamic acid by Brucella abortus.
The oxidation of glutamic acid by avirulent strains of Brucella abortus is the most rapid respiratory process thus far studied in this species (Gerhardt et al., 1950a). Furthermore, glutamic acid will serve as the sole source of both carbon and nitrogen for all strains of B. abortus which have been tested (Gerhardt et al., 1950b). Glutamic acid is important in the synthesis of other amino acids...
متن کاملKilling of Brucella abortus by bovine serum.
Studies of the serum bactericidal system in bovine brucellosis were undertaken to investigate the role of the humoral immune response in protection of cattle against the facultative intracellular parasite Brucella abortus. Fresh sera from normal control cattle, infected cattle, and cattle immunized with B. abortus cell envelopes were collected before treatment and during the course of immunizat...
