Luckily, a lot of personal egos haven't got in the way. Scientists are working together. The persistent Jancovich took months to uncover Ambystoma tigrinum , the culprit virus that may be responsible for the deaths of many amphibians. Particles of the Ambystoma tigrinum virus are revealed in a transmission electron microscope image. Virus particles are too small to be seen with an optical microscope.
Researchers can deduce the presence of a virus by filtration experiments.
The image directly confirmed the presence of virus in Arizona salamanders. Some of the researchers study whiteflies, others study Sonoran toads, tiger salamanders, or leopard frogs. The global teamwork has stacked up a bigger pile of questions than it has provided definitive answers. They could be hunters or fishermen traveling from state to state. Perhaps new species of amphibians introduced into non-native waters.
