New Added - New Parasite

Be prepared to freak out. http://www.emergingdisease.org/phpbb/index.php Yes, it says Emerging Diseases!

Coming from www.Bloomberg.com  is the story of how disease is making a species jump. That is normally diseases that mankind can't catch are mutating to where we can catch. Most diseases that animals can catch we are immune to. When humans to contract a mutation of a disease or bacteria it can be fatal. Not only the Avian Flu but more.

   Direct quotes are "Over the past 25 years, a total of 38 new pathogen species - - including viruses, bacteria, fungi and other organisms associated with infectious diseases in humans -- have been reported, Professor Mark Woolhouse, Chair of Infectious Disease Epidemiology at the University of Edinburgh, Scotland, said yesterday at a meeting of scientists in St. Louis, Missouri."

About two thirds of the new human pathogens are so-called RNA viruses, which have a small number of genes, making them more susceptible to mutation, Woolhouse said. More than 1,400 different pathogens that can infect humans, he said.

Species-jump may be on the increase because of changes in human behavior, including increased travel, changing climate, and higher rates of urbanization, Woolhouse said in a May 2005 paper published in the journal Trends in Ecology and Evolution.

Once a pathogen has made a species-jump, it ``is in a race between going extinct in the new host population and acquiring the genetic change that makes it sufficiently transmissible to persist in that population,'' Woolhouse said. ``RNA viruses, which can evolve very rapidly, may have the best chance of winning that race.''

 Other diseases thought to have emerged from animals in recent years include severe acute respiratory syndrome, or SARS, which is thought to have originated in civets, and ebola, whose origin is unknown. Other diseases have jumped between non-human species -- including canine distemper, an illness of dogs, which transmitted to seals in 1988, according to Woolhouse's paper.

"Recent “animal diseases” that have evolved into a form that can infect people include HIV, west nile virus, SARS, ebola, and monkey pox. Another common trait is that they are all retroviruses—viruses that do not contain DNA but another molecule that serves a similar purpose, called RNA."
