Measure of the disease-causing capacity of an infectious disease agent.
The degree of pathogenicity (ability of produce disease) of a microorganism as indicated by case fatality rates and/or its ability to invade the tissues of a host.
Capacity of a pathogen or insect to incite a disease or injury to the host. Degree or measure of pathogenicity.
Degree or severity of disease-causing potential of an organism.
the degree of pathogenicity of an organism as evidenced by the severity of resulting disease and the organism's ability to invade the host tissues.
adjective VIRULENT): aggressiveness, ability to cause disease.
"degree of pathogenicity"
an organism's ability to cause disease.
the relative ability of a microorganism to overcome the resistance of a host.
Ability of an organism to cause disease (Lecture: Overview of Bacterial Pathogenesis, 1/22/02)
The power of bacteria or viruses to cause a disease. Different strains of the same micro-organism can vary in virulence.
the capacity of a pathogenic organism to cause disease - defined broadly as the severity of symptoms in the host.
the ability of a microorganism to cause disease.
the power of a microorganism to cause grave disease.
the ability of the pathogen to produce disease.(empty)(empty)
Relative capacity to cause disease; degree or measure of pathogenicity of a pathogen. Sometimes restricted to cases in which races interact differentially with host cultivars.
The ability of a microbe to cause disease.
Refers to the proportion of persons with clinical disease who become severely ill or die.
extreme harmfulness (as the capacity of a microorganism to cause disease); "the virulence of the plague"
The measure of how many organisms, or how much exposure to an organism, is required to cause disease. For instance Shigella can be caused by as little as a few bacteria, while E. Coli can require millions of bacteria to cause problems.
The destructive or malignant properties of a disease.
the degree or ability of a pathogenic organism to cause disease.
the ability to cause rapid and severe disease.
The degree to which an infectious organism can cause serious disease or invade the host tissue.
poisonousness, infectiousness, endangering life.
The degree to which a disease-causing organism can affect the organism it attacks.
a measure of the ability of a pathogen to cause disease, whereby the more virulent the pathogen is, the more serious the disease it can cause.
The proportion of persons with clinical disease, who after becoming infected, become severely ill or die.
Capacity of a pathogen or insect to incite a disease or injury to the host. See Also: pathogen.
How well or quickly a virus or bacteria is able to cause disease in a person.
(Latin virulenctia = virus poison) morbidity and mortality of a host caused by parasites and pathogens (relative infectiousness).
The disease producing power of a microorganism.
aggressiveness, ability to cause disease. (adjective virulent)
Ability to infect or cause disease.
degree of pathogenicity of a pathogen, the relative capacity of a pathogen to cause disease.
The relative ability of an organism to cause disease.
An organism's ability to produce disease.
Degree of ability to cause disease.
Refers to the ability of a microorganism to produce serious disease. Tuberculosis is a virulent organism. Some nontuberculous mycobacteria are virulent (e.g., M. kansasii), while others (e.g., M. gordonae) are not. (PATHOGENICITY is a related--though not identical--concept.)
The degree of pathogenicity of a given pathogen. ()
