Coordinated cyclic-di-GMP repression of salmonella motility through YcgR and cellulose
Cyclic di-GMP (c-di-GMP) is a secondary messenger that controls a variety of cellular processes, including the switch between a biofilm and a planktonic bacterial lifestyle. This nucleotide binds to cellular effectors in ... -
Evaluation of a Salmonella strain lacking the secondary messenger c-di-GMP and RpoS as a live oral vaccine
Salmonellosis is one of the most important bacterial zoonotic diseases transmitted through the consumption of contaminated food, with chicken and pig related products being key reservoirs of infection. Although numerous ... -
Insights into c-di-GMP signaling and the PGA exopolysaccharide biological functions using Salmonella as a model organism
Salmonella es un patógeno alimentario de gran relevancia clínica capaz de adherirse a superficies y formar comunidades bacterianas embebidas en una matriz que ellas mismas producen denominadas biofilms. Esta matriz ... -
Lack of the PGA exopolysaccharide in Salmonella as an adaptive trait for survival in the host
Many bacteria build biofilm matrices using a conserved exopolysaccharide named PGA or PNAG (poly-β-1,6-N-acetyl-D-glucosamine). Interestingly, while E. coli and other members of the family Enterobacteriaceae encode the ... -
Obtención de un alelo de celulosa sintetasa capaz de producir celulosa en ausencia del activador alostérico c-di-GMP
La celulosa es uno de los principales componentes de la matriz extracelular de los biofilms formados por algunas especies bacterianas. Los genes involucrados en su síntesis, en el caso de Salmonella Enteritidis, se ... -
Salmonella biofilm development depends on the phosphorylation status of RcsB
The Rcs phosphorelay pathway is a complex signaling pathway involved in the regulation of many cell surface structures in enteric bacteria. In response to environmental stimuli, the sensor histidine kinase (RcsC) ... -
Simultaneous infections by different Salmonella strains in mesenteric lymph nodes of finishing pigs
Background: Salmonellosis is a major worldwide zoonosis, and Salmonella-infected finishing pigs are considered one of the major sources of human infections in developed countries. Baseline studies on salmonellosis ...
