has tremendous biodiversity and high rates of endemic species: of more than 200,000 known species found on Madagascar, more than 80 percent exist nowhere else. Unique to the island are over 100 kinds of lemurs, over 300 species of frogs, and 33 species of tenrecs, miniature hedgehog-like animals. However, it is one of the most threatened ecosystems on the planet.

Conventional genetic analyses of prions involving rrna sequences are impossible because Prions do not contain nucleic acids
The name "prions" refers to aberrant, pathogenic agents that are transmissible and capable of inducing improper folding of specific normal cellular proteins known as prion proteins, which are abundant in the brain.
Prions are virus-like creatures that contain a prion protein. These elongated fibrils (green) are thought to be protein aggregations from the infectious prion. Prions cause neurodegenerative brain illness by attacking nerve cells. Symptoms of "mad cow" include glassy eyes and uncontrollable bodily trembling.
Prion disorders develop when normal prion protein, which is found on the surface of many cells, becomes aberrant and clumps in the brain, causing harm to the brain.
