What else can I help you with?
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.
How do pathogen increase pathogen virulence?
Pathogens can increase their virulence through genetic mutations, acquisition of new virulence factors, suppression of host immune responses, or improved adaptation to host environment. This may result in enhanced ability to invade host tissues, evade immune detection, or cause more severe disease.
Attributes of an organism that promote pathogenicity are called?
Virulence factors
What is meant by the term attenuated pathogen?
An attenuated pathogen is a weakened form of a disease-causing microorganism that is used in vaccines to stimulate an immune response without causing the full-blown disease. Attenuated pathogens are less virulent than their wild-type counterparts, reducing the risk of causing illness in vaccinated individuals while still eliciting a protective immune response.
Is catalase usually considered a virulence factor of bacteria?
Catalase is not typically considered a virulence factor of bacteria. It is an enzyme that helps in the breakdown of hydrogen peroxide, a harmful byproduct of metabolism. While it can contribute to bacterial survival by detoxifying reactive oxygen species, it is not a direct virulence factor involved in causing disease.
A microorganism's disease-producing power is called?
virulence

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.
What are disease-producing microorganisms called?
They are usually just called organisms or bacteria, virus, pathogen, or parasites.

What is a virulence factor for diphtheria?
The virulence factor for diphtheria is an exotoxin named diphtheria exotoxin.

Do microorganisms with smaller infectious dose have greater or lesser virulence?
small infectious dose leads to greater virulence
