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.
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.
How does the rocky mountain spotted fever organism result in disease & what are the 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.
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.
candida produces parasites
Host receptors, transmission, virulence factors, host immune system etc.
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.

The primary virulence factors of propionibacterium acnes are lipase (which helps to break down the yucky oils/lipids on our face), hyaluronidase (which is an enzyme that breaks down the connective tissues and increases the permeability of connective tissues), neuraminidase, proteases, inflammatory mediators, and other enzymes.
Virulence is the state of being virulent, that is, highly infectious, malignant or deadly.
a gene in any pathogen which codes for the virulence factor like protein or polysacchride is called virulence gene and is denoted by Vir genes
The virulence factor for diphtheria is an exotoxin named diphtheria exotoxin.
Virulence - album - was created on 2007-01-23.
The virulence of the organism combined with the number of the invading organisms. As well as the resistance of the infected individual called the host.
small infectious dose leads to greater virulence
You can learn the definition of the word virulence online through websites such as Merrriam-Webster, Dictionary, and Vocabulary. You can also buy a dictionary in order to look up the word in there.

Plasmids are autonomous DNA molecules of varying size which are localized within the cytoplasm of bacteria. There are two kinds:virulence plasmids = determines the virulence factors of the bacteriaresistance plasmids (R-plasmids) = determines the bacteria's resistance to anti-infective agents
Pathogenicity refers to the ability of an organism to cause disease. Virulence refers to the degree of pathology caused by the organism
a microorganism that has decreased in virulence
A toxin is a poisonous substance produced by living cells or organisms. Toxins produced by microorganism are important virulence determinants responsible for microbial pathogencity and/or evasion the host immune response. This will alter the human physiology when taken so to avoid the bad effect of toxin it is first inactivated and then used as vaccine which is known as toxoid.
