Reptiles, Amphibians in US Succumbing to Deadly Ranavirus

描述：

Description: Since the mid 1990s, a type of virus known as a ranavirus has been taking a devastating toll on reptiles and amphibians -- especially turtles, frogs, toads and salamanders -- in more than 20 states across the U.S. Hundreds of thousands of these animals have died from the lethal virus and the disease continues to spread. Scientists are stepping up their efforts to better understand and combat the pathogen, and VOA's Zulima Palacio talked with some of them. Date: 13 April 2012. Source: http://youtu.be/pVYQK5WxGr8.
