Diseases and causes of death in European bats: dynamics in disease susceptibility and infection rates.
<h4>Background</h4>Bats receive increasing attention in infectious disease studies, because of their well recognized status as reservoir species for various infectious agents. This is even more important, as bats with their capability of long distance dispersal and complex social structu...

<h4>Background</h4>Bats receive increasing attention in infectious disease studies, because of their well recognized status as reservoir species for various infectious agents.
