A virulence factor helps pathogens become established, causing damage to the host. In gram negative bacteria that would be endotoxins from the bacterias outer membrane (LPS). In gram positive it would be a slime layer. In a virus it would be its spikes,isnce it helps the virus attach to the host cell. In bacteria it would be a immunoglobbin protease (enzyme), it breaks down the host immunoglobbins.

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.
Attributes of an organism that promote pathogenicity are called?
Virulence factors
What does not contribute to the virulence of a pathogen?
There are infinitely many things that do not contribute to the virulence of a pathogen. Elvis does not contribute to the virulence of a pathogen.
Are toxins virulence factors?
No. For something to be virulent it must be alive. Virulence usually refers to pathogens, like bacteria, viruses, and yeasts. But, pathogens, themselves, can create toxins by their metabolic activity. Still, however, the toxin itself wouldn't have the property of being virulent, only the "bug" would be.
Do microorganisms with smaller infectious dose have greater or lesser virulence?
small infectious dose leads to greater virulence
What is the size of neisseria?
It's bigger than the pores in sheet latex. (Neisseria is the bacteria that causes gonorrhea.)
What are the virulence factors of Rocky Mountain spotted fever?
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.
Neisseria?
Gram negative diplococcic 2) Kidney-bean shaped cocci that occur in pairs. 3) Obligate aerobes 4) Common inhabitants of animal / human mucous membranes. 5) Nutritionally fastidious 6) Neisseria gonorrhoeae - gonorrhea 7) Neisseria meningitidis - meningitis
What are Virulence factors of pathogens under exoenzymes and toxins?
Erythrogenic
Attributes of an organism that promote pathogenicity are called?
Virulence factors
What is pyogenic meningitis?
It is the inflammation of meninges,with the formation of pus over whole meninges, due to infections such as staphylococcus aureus,neisseria gonorrhea.
What does virulent bacteria mean?
Virulent bacteria are ones that are able to cause disease. Examples of potentially virulent bacteria are Staphylococcus aureus and Neisseria gonorrhea.
What are antiphagocytic factors produced by pathogens?
Alpha toxin by Staphylococcus aureus M protein of Streptococcus pyogenes Polypeptide capsule of Bacillus anthracis Pilli of Neisseria gonorrhea Polysaccharide capsule of Streptococcus pneumoniae, Klebsiella pneumoniae, Hemophillus influenzae, Pseudomonas aeruginosa
Is Neisseria meningitidis Gram-positive cocci?
Neisseria gonorrhoeae ( nīsə′rēə ′gänə′rē′ī ) ( microbiology ) A gram-negativecoccus pathogen that causes the sexually transmitted disease gonorrhea
