It is in “Proceedings of National Academy of Science” (PNAS), an American magazine, that the study has been published (the 10 April 2012). The original manuscript was submitted to the newspaper 9 January 2012 by Canadian researchers at the University of Manitoba in Winnipeg. This experimental work has allowed verification of the original 3rd postulate of Koch, that the inoculation of the organism causes disease isolated. More, According to these authors, White Nose Syndrome (WNS) and fatal features are observed in bats (Myotis lucifugus) inoculated and then placed in hibernation, regardless of the geographical origin of the strain used (European or American). The results of this study are in favor of the hypothesis of an invasive species of European origin that the systematic progression of the fungus to the American West and its wide distribution already seemed to describe European. This perspective appears sufficient to explain, to date, the difference in sensitivity observed populations of American and European bat. An ancient evolutionary history of the fungus with bats of the Old World, which have not benefited those in the new world where the fungus was introduced some years ago, would have favored the adaptation of species of the old continent and helped limit the pathology associated with the presence of the fungus. The latter hypothesis would be verified if the genetic mechanisms of resistance to infection by the fungus could be detected in European bats while they are absent, or much less represented, bat populations in the U.S.. The validation of this possibility and / or experimental evidence would undoubtedly minimize the risk associated with Geomyces destructans for European bat populations.
