Parks Canada crews are at work in Alberta's bat caves, spreading a blend of bacteria to try to save the flying night mammals from a deadly. And accelerating, fungal infection. Parks Canada crews are at work in Alberta's bat caves, spreading a blend of bacteria to try to save the flying night mammals from a deadly. And accelerating, fungal infection. Nina Veselka, a biologist with Parks Canada, has already seen the effects of the infection at a cave in Jasper National Park, where weary bats had fallen from the limestone walls. And struggled to survive from the cave floor. The scourge is white-nose syndrome and it is threatening Alberta's entire hibernating bat population.
