[font size=3]CHAMPAIGN, lll. — A small population of rattlesnakes that already is in decline in southern Illinois faces a new and unexpected threat in the form of a fungus rarely seen in the wild, researchers report.

The eastern massasauga rattlesnake (Sistrurus catenatus catenatus), a candidate for protection under the federal Endangered Species Act, suffers from habitat loss and environmental stresses wherever it is found, said University of Illinois comparative biosciences visiting instructor and wildlife veterinarian Matthew Allender, who led the health investigation. Long-term population studies of the snake – in Illinois and elsewhere – had never turned up evidence of debilitating fungal infections. But in 2008, biologists studying the snake reported to Allender that they had found three sick snakes in a park in southern Illinois, all with disfiguring lesions on their heads. The snakes died within three weeks of their discovery. A fourth snake with a similar syndrome was discovered in the same park in the spring of 2010.

“They seem to be having a similar problem in timber rattlesnakes in New Hampshire and Massachusetts,” Allender said. Although biologists have sporadically identified Chrysosporium in those snakes, the symptoms they report – facial swelling and ulcers and malformations of the jaw – are the same, he said. These infections also occurred only within the last five years.

“Fungal pathogens have been increasingly associated with free-ranging epidemics in wildlife, including the well-known effects of Batrachochytrium dendrobatidis on frog populations globally and white-nosed syndrome in bats,” Allender wrote in a December 2011 report in Emerging Infectious Diseases. “Both of these diseases cause widespread and ongoing deaths in these populations that seriously threaten biodiversity across the United States.”

Chrysosporium also is emerging as a dangerous infection in humans with weakened immune systems, he said.
