hypervirulent

The researchers do not know what the infectious dose is, or enough about hypervirulent strains.

Recently a hypervirulent strain was discovered in China.

Mycobacterium outbreaks are often caused by hypervirulent strains of M. tuberculosis.

Studies have shown the majority of hypervirulent mutants have deletions in their cell wall-modifying enzymes or regulators that respond to environmental stimuli.

Scorpion toxin genes are also used to kill insect pests by creating hypervirulent fungus in the insect through gene insertion.

To prevent hypervirulent strains from arising and spreading rapidly due to monoculture, cultivar mixtures are commonly employed in mango plantations.

They are known as the "Great Fire", "Great Drought", "Blitzkrieg", "Biological Invasion", "Hypervirulent Disease", and "Synergy" hypotheses.

However, most serious S. aureus infections in the community, and many in hospitals, are caused by methicillin-susceptible isolates (MSSA) and there have been few attempts to identify the hypervirulent MSSA clones associated with serious disease.
