Abstract Salmonellosis is an extremely contagious disease caused by bacteria of the genus Salmonella which affects both humans and animals. a cause for concern in cattle business because it zoonotic that can serious invasive infections people besides, infected herds suffer economic welfare losses. Consequently, SIRB (Susceptible - Infected Recovered-Bacteria) model being constructed to study tr...
A chromosomal region present in Salmonella typhimurium but absent from related species was identified by hybridization. A DNA probe originating from 78 min on the S. typhimurium chromosome hybridized with DNA from Salmonella enteritidis, Salmonella heidelberg, and Salmonella dublin but not with DNA from Salmonella typhi, Salmonella arizonae, Escherichia coli, and Shigella serotypes. Cloning and...
Salmonella enterica subspecies enterica serovar Dublin (S. Dublin) figures among the most frequently isolated Salmonella strains in humans in France. This serovar may affect production and animal health mainly in cattle herds with corresponding high economic losses. Given that the current gold standard method, pulsed-field gel electrophoresis (PFGE), provides insufficient discrimination for epi...
We have used signature-tagged mutagenesis to identify mutants of the host-specific Salmonella enterica serotype Dublin which were avirulent in calves and/or BALB/c mice. A mutant with a transposon insertion in the sseD gene of Salmonella pathogenicity island 2 (SPI-2), which encodes a putative secreted effector protein, was identified. This mutant was recovered from the bovine host but not from...
Interactions between CD40 expressed on macrophages and CD40 ligand expressed on T lymphocytes can be an important signal for optimal macrophage activation. Previous studies have demonstrated that the optimal response against certain intracellular pathogens (e.g., Crytosporidium and Leishmania spp.) by macrophages requires CD40-CD40 ligand interactions. However, this finding is not universal, si...
