The Tricarballylate utilization (tcuRABC) genes of Salmonella enterica serovar Typhimurium LT2.
The genes of Salmonella enterica serovar Typhimurium LT2 encoding functions needed for the utilization of tricarballylate as a carbon and energy source were identified and their locations in the chromosome were established. Three of the tricarballylate utilization (tcu) genes, tcuABC, are organized as an operon; a fourth gene, tcuR, is located immediately 5' to the tcuABC operon. The tcuABC ope...
متن کاملComparison of Salmonella enterica serovar Typhimurium LT2 and non-LT2 salmonella genomic sequences, and genotyping of salmonellae by using PCR.
Genes of Salmonella enterica serovar Typhimurium LT2 expected to be specifically present in Salmonella were selected using the Basic Local Alignment Search Tool (BLAST) program. The 152 selected genes were compared with 11 genomic sequences of Salmonella serovars, including Salmonella enterica subsp. I and IIIb and Salmonella bongori (V), and were clustered into 17 groups by their comparison pa...
متن کاملNew antibiotic substance produced by Salmonella typhimurium LT2.
Salmonella typhimurium LT2 excreted under certain conditions an antibiotic substance designated typhimuricin. It is suggested that the LT2 "cryptic" plasmid is involved in its production and in the immunity to it. Preliminary characterization of typhimuricin is presented.
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...
متن کاملUtilization of 2,6-diaminopurine by Salmonella typhimurium.
The pathway for the utilization of 2,6-diaminopurine (DAP) as an exogenous purine source in Salmonella typhimurium was examined. In strains able to use DAP as a purine source, mutant derivatives lacking either purine nucleoside phosphorylase or adenosine deaminase activity lost the ability to do so. The implied pathway of DAP utilization was via its conversion to DAP ribonucleoside by purine nu...
