A wild abalone taken from waters off southern Tasmania has tested positive to a potentially devastating virus. State chief veterinary officer Rod Andrewartha yesterday confirmed the wild abalone had abalone viral ganglioneuritis (AVG). It has prompted the closure of a 229 square kilometre fishing area. The seabed in the D'Entrecasteaux Channel between Port Esperance and Southport was closed to commercial and recreational abalone industries from midnight.

The positive test was confirmed by Will County Environmental Health on Friday, said the county's health department. Will County is the 19th county in Illinois to report West Nile virus activity in 2008. Statewide, there have been five human cases, 16 birds and 459 mosquito batches reported through Friday.

USGS and a network of partners across the country work on documenting wildlife mortality events in order to provide timely and accurate information on locations, species and causes of death. This information was updated on Sep 15, 2008 on the USGS National Wildlife Health Center web page, New and Ongoing Wildlife Mortality Events Nationwide. Quarterly Mortality Reports are also available from this page. These reports go back to 1995.




Why some primates, but not humans, can live with immunodeficiency viruses and not progress to AIDS

Key differences in immune system signaling and the production of specific immune regulatory molecules may explain why some primates are able to live with an immunodeficiency virus infection without progressing to AIDS-like illness, unlike other primate species, including rhesus macaques and humans, that succumb to disease. Following the identification of HIV (Human Immunodeficiency Virus) as the cause of AIDS 25 years ago, an extensive search was undertaken to identify the source of the virus. These studies led to the discovery that chimpanzees and sooty mangabeys are infected in the wild with simian immunodeficiency viruses (SIV), whose transmission to humans and macaques leads to AIDS. Surprisingly, the natural hosts for the AIDS viruses, such as the mangabeys and numerous other African primate species who have been found to harbor SIVs in the wild, remain healthy despite infection.
