Invasiveness in chickens, stress resistance and RpoS status in wild-type Salmonella enterica subsp. enterica serovar Typhimurium definitive type 104 and serovar Enteritidis phage type 4 strains

Article Abstract:

Research has been conducted on clinical and environmetal strains of Salmonella enterica subsp. enterica serovar Typhimurium definitive type 104. Results demonstrate that three definitive type 104 strains are more sensitive to stresses in stationary phase.

Porins from Salmonella enterica serovar Typhimurium induce TNF-alpha, IL-6 and IL-8 release by CD14-independent and CD11a/CD18-dependent mechanism

Article Abstract:

Research has been conducted on the Gram-negative bacteria lipopolysaccharide whish utilizes CD14 and CD11a/18 as cellular receptors in inducing cytokine expression and release. Results indicate that the stimulation mechanism by THP-1 cell porins enriched in the CD14 receptor is independent of this receptor but dependent on CD11a/CD18 integrins.

The Chryseobacterium meningosepticum PafA enzyme: prototype of a new enzyme family of prokaryotic phosphate-irrepressible alkaline phosphatases?

Article Abstract:

Research has been conducted on the Chryseobacterium meningosepticum producing a phosphate-irrepressible periplasmic alkaline phosphatase. The cloning of the gene encoding C. meningosepticum enzyme and the characterization of its product have been carried out and examined.
