[size 1]The disease is not caused by a virus, but a single-celled parasite with the
-spinning title of Myxobolus cerebralis. Its life cycle waltzes between two hosts: trout and the bottom-dwelling tubifex worm. A changeling microspore that alters form in each host, the disease can turn young trout into horror show aliens with blackened tails, bulging eyes and deformed humps by feeding on cartilage near their heads. The resulting damage to the nervous system and skeletal integrity launches young fish into a kind of permanent spin cycle that gives the disease its name. Fingerlings are particularly vulnerable to heavy infestations, since their soft cartilage has not yet hardened into bone. While adult fish are not visibly affected, they often serve as spore carriers. Nonetheless, infected fish are edible and pose no health hazard to humans.[/size] [url "http://www.gmfsh.state.nm.us/PageMill_TExt/Fishing/whirlingcycle.html"][#0000ff][size 1]Life Cycle of Whirling Disease[/size][/#0000ff][/url]
