Systematics[ edit ] This section needs expansion with: You can help by adding to it. February The scientific name is sometimes written Ophiocordyceps unilateralis sensu latowhich means "in the broad sense".
This is because the species is actually a complex of many species within O. The stalk has perithecia just below its tip. Once infected with the fungus, the ant will climb down from its normal habitat and bite down on the underside of a leaf.
This is known as "the death grip" and occurs in very specific locations. However, the fungus may parasitize other closely related species of ants with lesser degrees of host manipulation and reproductive success.
Infections may lead to 20 to 30 dead ants per square meter. The ant is no longer able to control the muscles of the mandible and will remain fixed in place. This process takes four to ten days.
In response, ants have the ability to sense that a member of the colony is infected; healthy ants will carry the dying one far away from the colony in order to avoid fungal spore exposure.
The fungal pathogen must attach securely to the arthropod exoskeleton and penetrate it—avoiding or suppressing host defenses—then, control the behavior of the host before killing it; and finally, it must protect the carcass from microbial and scavenger attack.
These attributes also make it a prime candidate for anti-tuberculoid testing in secondary TB patients, by improving symptoms and enhancing immunity when combined with chemotherapeutic drugs. This is caused by the castration of the fungus by the hyperparasite, which may cause the limiting of the viable infectious spores.
Ants also groom each other to combat microscopic organisms that could potentially harm the colony. This shows that the colony is not in as much danger as previously thought. Additional fungi grant beneficial assistance to the colony as well.If you are more interested in the best poems of Modernism, please continue reading.

Columbus, in his "discovery" of the Western World, was the beginning spark which ignited the interest of all the leading powers.
This resulted in a series of expeditions sent forth for the purpose of acquiring these valuable lands, their rich natural resources and wealth. Ophiocordyceps unilateralis is an entomopathogen, or insect-pathogenising fungus, discovered by the British naturalist Alfred Russel Wallace in , and currently found predominantly in tropical forest ecosystems.
O. unilateralis infects ants of the Camponotini tribe, with the full pathogenesis being characterized by alteration of the .
