TranscriptomicsGlobal Rsh-dependent transcription profile of Brucella suis during stringent response unravels adaptation to nutrient starvation and cross-talk with other stress responses.
In the intracellular pathogen Brucella spp., the activation of the stringent response, a global regulatory network providing rapid adaptation to a variety of growth-affecting stress conditions such as nutrient deficiency, is essential for replication in the host. A single, bi-functional enzyme Rsh c...

TranscriptomicsBrucella melitensis-infected HeLa cells gene expression
In a time course study, we characterized global gene expression profile of B. melitensis-infected epithelium-like cells at the onset of infection. B. melitensis-infected HeLa cells exhibited a down-regulated expression profile at 4 h (48 up- and 109 down-regulated genes) that transitioned to an acti...

TranscriptomicsBovine Peyer's Patch Infected with Mycobacterium avium ssp. paratuberculosis and Mycobacterium avium ssp. avium
Mycobacterium avium subspecies paratuberculosis (MAP) infection is established following the ingestion of bacteria, their penetration of the intestinal mucosa and subsequent events of the host-parasite interaction. These bacteria invade M cells, macrophages and are capable of resisting host defenses...

TranscriptomicsRole of SPI-1 Secreted Effectors, SipA, SopABDE2, in Acute Bovine Response to Salmonella enterica Serovar Typhimurium
Salmonella enterica Serovar Typhimurium (S. Typhimurium) causes enterocolitis in humans and calves characterized by diarrhea and polymorphonuclear cell (PMN) influx to the intestinal mucosa. The Salmonella Type III Secretion System encoded at Pathogenicity Island I (SPI-1) translocates the Salmonel...
