Therapeutic efficacy of tumor-targeting Salmonella typhimurium A1-R on human colorectal cancer liver metastasis in orthotopic nude-mouse models. [PDF]
Liver metastasis is the most frequent cause of death from colon and other cancers. Generally, liver metastasis is recalcitrant to treatment. The aim of this study is to determine the efficacy of tumor-targeting Salmonella typhimurium A1-R on liver ...

Gene ilvY of Salmonella typhimurium [PDF]
Evidence is presented for the existence in Salmonella typhimurium LT2 of the regulatory gene ilv Y. The Escherichia coli K-12 ilvY gene product is shown to complement a S. typhimurium ilvY mutation in vivo.

Overproduction of Salmonella typhimurium peptidase T [PDF]
Pseudorevertants able to use L-leucyl-L-leucyl-L-leucine as a leucine source have been isolated from a Salmonella typhimurium strain carrying stable (nonreverting) mutations in pepN, pepA, and pepB. These strains carry mutations at a locus pto (peptidase T overproducer) tightly linked to pepT that cause an elevated expression of the tripeptidase ...

Transport of trehalose in Salmonella typhimurium [PDF]
We have studied trehalose uptake in Salmonella typhimurium and the possible involvement of the phosphoenolpyruvate:carbohydrate phosphotransferase system (PTS) in this process. Two transport systems could recognize and transport trehalose, the mannose PTS and the galactose permease.

Salmonella Typhimurium resides largely as an extracellular pathogen in porcine tonsils, independently of biofilm-associated genes csgA, csgD and adrA [PDF]
In European countries, Salmonella enterica subspecies enterica serovar Typhimurium (Salmonella Typhimurium) is the serovar most frequently isolated from slaughter pigs1.

The immunological relationship between filtrable agent, Salmonella and murine leukosis [PDF]
Salmonella typhimurium was invariably isolated from our J strain murine leukosis. Immunization of D103 mice with either inactivated Salmonella typhimurium or the cell-free extract of leukosis inhibited the transplantation of leukosis.

The Induction of Lysogenesis in Salmonella typhimurium [PDF]
SUMMARY: After exposure to phage A1 an organism of an indicator strain of Salmonella typhimurium may burst with phage liberation, may become lysogenic, or may develop into a mixed progeny of lysogenic and phage-sensitive bacteria. By the methods we have used, the proportion of such mixed progenies is about 20% of the number of lysogenic colonies found.

Tissue-specific Salmonella Typhimurium gene expression during persistence in pigs [PDF]
Salmonellosis caused by Salmonella Typhimurium is one of the most important bacterial zoonotic diseases. The bacterium persists in pigs resulting in asymptomatic 'carrier pigs', generating a major source for Salmonella contamination of pork.

Colicinogeny in Salmonella typhimurium [PDF]
Colicin types, Ia, Ib, E1, E2, B with M, K, S4 and a new salmonellin-like colicin were found in 531 (11.8%) of 4481 wild-type cultures of Salmonella typhimurium. Colicin typing added little useful information to phage typing and biotyping in strain differentiation, mainly because the most common types, Ia and Ib, are controlled by conjugative plasmids.
