Interactions between Bacteria and Bile Salts in the Gastrointestinal and Hepatobiliary Tracts
(Frontiers Media, 2017)
Bile salts and bacteria have intricate relationships. The composition of the intestinal pool of bile salts is shaped by bacterial metabolism. In turn, bile salts play a role in intestinal homeostasis by controlling the ...
Tesis Doctoral
Adaptation to bile in salmonella enterica
(2013)
Las bacterias pertenecientes al género Salmonella son patógenos Gramnegativos capaces de infectar una gran variedad de animales. En humanos, la infección por Salmonella suele comenzar con la ingestión de agua o alimentos ...
Tesis Doctoral
Contribución del regulon Rcs a la virulencia de Salmonella análisis genético y molecular
(2008)
En el momento de iniciar esta tesis, trabajos recientes de nuestro laboratorio en colaboración con el Dr. García del Portillo habían descrito que alelos viables del gen esencial igaA activaban el sistema de transducción ...

Tubulin Folding Cofactor TBCB is a Target of the Salmonella Effector Protein SseK1
(MDPI, 2020)
Salmonella enterica serovar Typhimurium is a human and animal pathogen that uses type III secretion system effectors to manipulate the host cell and fulfill infection. SseK1 is a Salmonella effector with glycosyltransferase ...

Epigenetic control of O-antigen length in Salmonella entérica
(2016-01-12)
El locus STM2209-STM2208 (opvAB) es exclusivo de Salmonella enterica y presenta características típicas de genes adquiridos por transferencia horizontal. Fue descrito inicialmente como un locus reprimido por metilación ...

The NEL Family of Bacterial E3 Ubiquitin Ligases
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Some pathogenic or symbiotic Gram-negative bacteria can manipulate the ubiquitination system of the eukaryotic host cell using a variety of strategies. Members of the genera Salmonella, Shigella, Sinorhizobium, and Ralstonia, ...

Type III Secretion Effectors with Arginine N-Glycosyltransferase Activity
(MDPI, 2020)
Type III secretion systems are used by many Gram-negative bacterial pathogens to inject proteins, known as effectors, into the cytosol of host cells. These virulence factors interfere with a diverse array of host signal ...
Tesis Doctoral
Genetic and molecular analysis of small regulatory RNAs in Salmonella enterica
(2010)
En bacterias, los ARN no codificantes reguladores o "ARNs pequeños" (sRNA) regulan la expresión de genes-diana interaccionando con la región 5’ no traducida del ARN mensajero y facilitando o dificultando el acceso del ...

Analysis of Salmonella lineage-specific traits upon cell sorting
(Frontiers Media SA, 2023-03-29)
Microbial cell individuality is receiving increasing interest in the scientific community. Individual cells within clonal populations exhibit noticeable phenotypic heterogeneity. The advent of fluorescent protein technology ...

Salmonella Heterogeneously Expresses Flagellin During Colonization of Plants
(MDPI, 2020)
Minimally processed or fresh fruits and vegetables are unfortunately linked to an increasing number of food-borne diseases, such as salmonellosis. One of the relevant virulence factors during the initial phases of the ...
