Phinet Information
Pathogen Name: Salmonella spp.
Pathogen NIAID Category: NIAID Category B
Bio-objects
Bio-object 1: Cell apoptosis induction
  • Type: Pathway or action
  • Location: Cytoplasm
  • Description: Salmonella modulates host cell death to cause disease. By inducing cell death, Salmonella can effectively escape from the host cells and re-infect new cells, and also remove host effector cells.(<a href="#reference5464">Paesold et al., 2002</a>)(<a href="#reference5465">Zhou et al., 2000</a>)
Bio-object 2: Cytoskeletal actin modification
  • Type: Pathway or action
  • Location: Cytoplasm
  • Description: Salmonella induces cytoskeletal actin modification at the site of bacterial contact with the host cell membrane.(<a href="#reference5463">Hayward et al., 1999</a>)
Bio-object 3: Cytoskeletal rearrangements
  • Type: Pathway or action
  • Location: Cytoplasm
  • Description: Salmonella engage host cell signalling pathways to effect a crucial host cell response for invasion, namely rearrangement of the actin cytoskeleton.(<a href="#reference5463">Hayward et al., 1999</a>)
Bio-object 4: Modification of Rac, Cdc Rho GTPases
  • Type: Pathway or action
  • Location: Cytoplasm
  • Function: Enzyme activator
  • Description: SopE directly activates Cdc42 and Rac, two Rho family GTPases that are required for Salmonella invasion.(<a href="#reference5462">Hardt et al., 1998</a>)
Bio-object 5: Needle like structure formation
  • Type: Pathway or action
  • Location: Extracellular
  • Function: Transporter
  • Description: The type III secretion needle complex (NC) of Salmonella is a complex secretory system that functions to translocate virulence proteins into eukaryotic cells.(<a href="#reference5459">Kimbrough et al., 2000</a>)
Bio-object 6: PrgI, PrgJ proteins secretion
  • Type: Protein or gene complex
  • Location: Extracellular
  • Function: Transporter
  • Description: The type III secretion system - dependent phase begins with the secretion and assembly of needle components (PrgI, PrgJ proteins).(<a href="#reference5458">Sukhan et al., 2003</a>)(<a href="#reference5459">Kimbrough et al., 2000</a>)
Bio-object 7: Salmonella in vacuole. SseB, C, D proteins secretion
  • Type: Microorganism or its component
  • Location: Organelle -- Phagosome
  • Description: SseB (secretion system effector), SseC, SseD proteins are secreted by the type III secretion system 2 and function as a translocon for the translocation of Ste (Salmonella translocated effector) proteins from intraphagosomal Salmonella over the phagosomal membrane into the host cell.(<a href="#reference5469">Nikolaus et al., 2001</a>)
Bio-object 8: Salmonella in vacuole. Type III Secretion System 2
  • Type: Microorganism or its component
  • Location: Bacterial membrane or virus envelope
  • Function: Transporter
  • Description: Salmonella has a second type III secretion system. The TTSS2 is important for bacterial replication in macrophages. The TTSS2 is activated after bacteria enter into host cells and influences the fate of the Salmonella-containing vacuole (SCV).(<a href="#reference5468">Meresse et al., 2001</a>)
Bio-object 9: Salmonella internalization in vacuole
  • Type: Pathway or action
  • Location: Organelle -- Phagosome
  • Description: Salmonella is a facultative intracellular pathogen that inhabits a vacuolar compartment, called the Salmonella-containing vacuole (SCV), in infected host cells.(<a href="#reference5466">Steele-Mortimer et al., 2002</a>)
Bio-object 10: Salmonella Intracellular proliferation
  • Type: Pathway or action
  • Location: Cytoplasm
  • Description: It has also been proposed that the macrophages are the main host cells in which Salmonella proliferates in vivo. The mechanism by which Salmonella promotes intracellular proliferation is currently unknown.(<a href="#reference5466">Steele-Mortimer et al., 2002</a>)
Bio-object 11: Salmonella intracellular survival and replication
  • Type: Pathway or action
  • Location: Cytoplasm
  • Description: Localized reorganization of the actin cytoskeleton is associated with intracellular replication of Salmonella in representatives of differentiated cell types (macrophage, epithelial), indicating that it is likely to be a general characteristic of Salmonella during intracellular growth.(<a href="#reference5467">Mills et al., 1998</a>)(<a href="#reference5468">Meresse et al., 2001</a>)
Bio-object 12: Salmonella systemic spread
  • Type: Pathway or action
  • Location: Cell membrane
  • Description: The TTSS2 is important for systemic infection in host cells.(<a href="#reference5470">Villarreal-Ramos et al., 2000</a>)
Bio-object 13: SipA, B, C, D translocation into the host cells
  • Type: Pathway or action
  • Location: Cell membrane
  • Function: Enzyme activator
  • Description: The Sip proteins SipA, SipB, SipC, SipD (Salmonella invasion protein; also called Ssp for Salmonella secreted protein) are involved in invasion. SipA binds directly to actin in the host cells. SipB, SipC SipD are directly involved in the translocation process, and are themselves delivered to the cytosol of the host cell.(<a href="#reference5460">Collazo et al., 1997</a>)
Bio-object 14: SopA, B, D, E translocation into the host cells
  • Type: Pathway or action
  • Location: Cell membrane
  • Function: Enzyme activator
  • Description: Sop A, SopB, SopD, SopE proteins are translocated into eukaryotic cells via a Sip-dependent pathway. SopA influences the induction of enteritis. SopB, SopD act to mediate inflammation.(<a href="#reference5461">Wood et al., 2000</a>)
Bio-object 15: Type III Secretion System 1
  • Type: Pathway or action
  • Location: Bacterial membrane or virus envelope
  • Function: Transporter
  • Description: Type III secretion system (TTSS) transports bacterial proteins into the cytosol of the host cells.(<a href="#reference5458">Sukhan et al., 2003</a>)
