Component
Viral virulence
Capacity of viral variants to cause disease in the experimental host context.
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
Variants arising in the deficient-host passage model showed increased virulence that could persist after transfer to nutritionally adequate mice.
Experimental context and source evidence
- availability_state
- Experimental Coxsackievirus passage through selenium-deficient mice.
- experimental_scope
- Animal passage experiments; related influenza findings are reported, and vitamin E deficiency produced a similar Coxsackievirus effect.
- limitations
- The molecular route to individual mutations is unresolved. Selenium is not unique in this respect, and generalization to human infections remains uncertain.
- trigger_kind
- nutrient_deficiency

selenium deficiency or vitamin E deficiency in experimental mice ↓ changed host oxidative / immune environment ↓ selection or emergence of viral genomic variants ↓ increased virulence can persist after transfer to nutritionally adequate mice Demonstrated in animal models: [10] Coxsackievirus B3: a normally avirulent strain acquired reproducible genomic changes and increased virulence after passage through selenium-deficient mice.

Feed mice a selenium-deficient diet. Infect with **benign coxsackievirus B3 (CVB3/0)**. The virus becomes **virulent** — and sequencing shows **specific, heritable point mutations** in the viral genome that persist when the mutated virus is passaged into selenium-replete mice.
