Early-life exposure of frogs to herbicide increases mortality from fungal disease
Date:10/23/2013

bians to atrazine could reduce lasting increases in the risk of mortality from a disease associated with worldwide amphibian declines."

Until this study, scientists knew little about how early-life exposure to stressors affected the risk of infectious diseases for amphibians later in life.

"Identifying which, when, and how stressors cause enduring effects on disease risk could facilitate disease prevention in wildlife and humans, an approach that is often more cost-effective and efficient than reactive medicine," Rohr said.

The findings are also the latest chapter in research Rohr and his lab has conducted on the impact of atrazine on amphibians. These findings are consistent with earlier studies that concluded that, while the chemical typically does not directly kill amphibians and fish, there is consistent scientific evidence that it negatively impacts their biology by affecting their growth and immune and endocrine systems.
