Induction of immunoenhancing factors for murine splenocyte cultures by Salmonella typhimurium ribosome and ribonucleic acid extracts.
Ribosomal and ribonucleic acid (RNA)-rich preparations derived from Salmonella typhimurium were examined for their ability to enhance the primary in vitro antibody response of normal mouse spleen cell cultures to sheep erythrocytes. Both of these fractions were consistently more active in elevating the antibody response of normal mouse splenocytes from lipopolysaccharide (LPS) responder mice th...
متن کاملFlagellar synthesis in Salmonella typhimurium: requirement for ribonucleic acid synthesis.
The micro-complement-fixation assay has been demonstrated to be a sensitive assay for flagella which occur in nanogram amounts. By use of this assay, it was found that flagellar synthesis occurs during starvation of Salmonella typhimurium for tryptophan, an amino acid not present in flagellar protein. Under these conditions net ribonucleic acid (RNA) synthesis was reduced to approximately 10% o...
متن کاملMethionine synthesis by extracts of Salmonella typhimurium.
1. Following the genetic studies by Smith (1961) and Smith & Childs (1963) with methionine auxotrophs of Salmonella typhimurium, methionine formation from homocysteine has been investigated with cell-free extracts of this organism. 2. As found with Escherichia coli (Woods, Foster & Guest, 1964), methyl groups are formed by an N(5)N(10)-methylenetetrahydrofolate reductase. They are then transfer...
متن کاملPrecursor ribosomal ribonucleic acid and ribosome accumulation in vivo during the recovery of Salmonella typhimurium from thermal injury.
When cells of S. typhimurium were heated at 48 C for 30 min in phosphate buffer (pH 6.0), they became sensitive to Levine Eosin Methylene Blue Agar containing 2% NaCl (EMB-NaCl). The inoculation of injured cells into fresh growth medium supported the return of their normal tolerance to EMB-NaCl within 6 hr. The fractionation of ribosomal ribonucleic acid (rRNA) from unheated and heat-injured ce...
متن کاملIsolation and Detection of Virulence factors of Salmonella typhimurium and Salmonella enteritidis
Plasmids play an important role in the virulence and antibiotic resistance of Salmonella. Salmonella carry plasmids having different size and number. Plasmid profile analysis of single isolates of Salmonella typhimurium and Salmonella enteritidis revealed the presence of 4- plasmid profiles. Salmonella serovars produce several Type III secretions including Sop-E and Sop –B. Soap E is detected b...
