How does the rocky mountain spotted fever organism result in disease & what are the virulence factors?
What are virulence factors?
Virulence is the degree of pathogenicity within a types of parasites. The factors of virulence are the colonization of a niche in the host, immunoevasion, immunosuppression, entry and exit of cells and obtaining nutrition from the host.
Microbial virulence factors?
The virulence factor list include capsules, fimbriae, outer membrane proteins, techoic acids, protein A, and m protein. Virulence factors are factors that allow pathogens to avoid host defense mechanisms and adversely affect the host.
What is a virulence marker?
A virulence marker is a diagnostic tool in detecting viral factors. The importance of identifying viral factors lies in opportunities for prevention and to identify modes of transmission.
What are Virulence factors of pathogens under exoenzymes and toxins?
Erythrogenic
Attributes of an organism that promote pathogenicity are called?
Virulence factors
When does moderate and severe inflammatory types of acne occur?
result after the plugged follicle is invaded by Propionibacterium acnes, a bacteria that normally lives on the skin. A pimple forms when the damaged follicle weakens and bursts open, releasing sebum, bacteria, and skin
What are parasites and their virulence factors also What are some diseases that are parasitic?
candida produces parasites
Propionibacterium?
Gram + pleomorphic rods; Diphtheroids 2) Aerotolerant anaerobes, i.e, obligate fermenters - only produce ATP via SLP. 3) Inhabit anaerobic microenvironments of the skin (hair follicles). 4) Produce propionic acid as 1^ fermentation end product. 5) Ferment lactic acid; extract residual energy from a waste product of other bacteria. 6) Propionibacterium acnes - Acne (p. 523)
