What is avirulent?
: not virulent or pathogenic : not capable of causing disease avirulent strains of salmonellae avirulent viruses.
What is avirulent strain?
The avirulent strain of plant pathogens is spreading and living with a virulent strain of plant pathogen on the host or nonhost plant in the fields. The existence of many strains of plant pathogens, living in one niche leads the interaction among them.
What does non virulent mean?
adj. a (of a microorganism) extremely infective. b (of a disease) having a rapid course and violent effect. 2 extremely poisonous, injurious, etc. 3 extremely bitter, hostile, etc.
What is avirulent bacteria?
glycinea likely functions indirectly to elicit resistance in soybean, that is, evidence suggests the gene product is an enzyme involved in elicitor production. In most if not all cases, bacterial avirulence gene function is dependent on interactions with the hypersensitive response and pathogenicity (hrp) genes.
What does insipidity mean?
1 : lacking in qualities that interest, stimulate, or challenge : dull, flat insipid prose. 2 : lacking taste or savor : tasteless insipid food.
What is a Avirulent vaccine?
From Wikipedia, the free encyclopedia. An attenuated vaccine (or a live attenuated vaccine) is a vaccine created by reducing the virulence of a pathogen, but still keeping it viable (or “live”). Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent.
What do you mean by pathogenicity?
Specifically, pathogenicity is the quality or state of being pathogenic, the potential ability to produce disease, whereas virulence is the disease producing power of an organism, the degree of pathogenicity within a group or species.
What does Toxigenicity mean?
toxigenicity. The ability of a pathogenic organism to produce injurious substances that damage the host.
What is a virulent virus?
Definition. A virus that lyses its host immediately upon infection and often cause disease. Supplement.
Can bacteria be virulent?
Virulence is described as an ability of an organism to infect the host and cause a disease. Virulence factors are the molecules that assist the bacterium colonize the host at the cellular level.
What is definition of infection?
(in-FEK-shun) The invasion and growth of germs in the body. The germs may be bacteria, viruses, yeast, fungi, or other microorganisms. Infections can begin anywhere in the body and may spread all through it. An infection can cause fever and other health problems, depending on where it occurs in the body.
What is the definition of strain in physics?
What is Strain in Physics? | Definition, Formulas, Symbols, Types – Elasticity 1 The fractional change in configuration is called strain. 2 A strain is the response of a system to an applied stress. When a material is loaded with a force, it produces a… More
How is the strain of a material related to the stress?
There was a linear region where the force required to stretch the material was proportional to the extension of the material. This is known as Hooke’s Law. Hooke’s Law states that the strain of the material is proportional to the applied stress within the elastic limit of that material.
What is the definition of an avirulent organism?
Avirulent definition, (of organisms) having no virulence, as a result of age, heat, etc.; nonpathogenic. See more.
What is the definition of a longitudinal strain?
A longitudinal strain is defined as. Change in the length to the original length of an object. It is caused due to longitudinal stress and is denoted by the Greek letter epsilon ε. 1. Shearing strain is measured as a change in angle between lines that were originally perpendicular.
