Metabolism of pyrimidines and pyrimidine nucleosides by Salmonella typhimurium.
The pathways by which uracil, cytosine, uridine, cytidine, deoxyuridine, and deoxycytidine are metabolized by Salmonella typhimurium are established. The various 5-fluoropyrimidine analogues are shown to exert their toxic effects only after having been converted to the nucleotide level, and these conversions are shown to be catalyzed by the same enzymes which similarly convert the natural subst...
متن کاملThe Metabolism of Thiosulfate in Salmonella Typhimurium.
Inorganic thiosulfate has been implicated as an intermediate in the assimilation of sulfate in a variety of organisms. Nutritional studies with mutants of Aspergillus have been interpreted to indicate thiosulfate as an intermediate between sulfite and cysteine (1, 2), possibly via a pathway involving cysteine-Ssulfonate as a direct precursor of cyst&e (24). Shepherd earlier had envisioned the u...
متن کاملModulation of virulence by two acidified nitrite-responsive loci of Salmonella enterica serovar Typhimurium.
Two acidified nitrite-inducible genes of Salmonella enterica serovar Typhimurium were identified with a green fluorescent protein-based promoter-trap screen. The nitrite-inducible promoters were located upstream of loci that we designated nipAB and nipC, which correspond to hcp-hcr (hybrid cluster protein) of Escherichia coli and norA of Alcaligenes eutrophus, respectively. Maximal induction of...
متن کاملImmunogenic potential of a Salmonella Typhimurium live vaccine for pigs against monophasic Salmonella Typhimurium DT 193
BACKGROUND Monophasic Salmonella Typhimurium (mSTM) strains account for up to 8.6% of all human Salmonellosis cases. They have an increasing prevalence during recent years and several human cases with hospitalisation were reported. These strains are often isolated from pigs and pork - one primary source of human infection. A Salmonella Typhimurium (STM) live vaccine has been proven successful i...
متن کاملInhibitory Potential of Metabolites from Lactobacillus casei against Phenotypic Characteristics of Salmonella typhimurium LT2
ABSTRACT Background and Objective: Several studies have shown the antimicrobial activity of lactobacilli against Salmonella enterica (serotype typhimurium). The aim of this study was to evaluate the inhibitory potential of metabolites produced by probiotic culture of Lactobacillus casei against S. typhimurium and its impact on S. ty...
