Summary: Scientists have found that a newly identified and highly infectious tadpole disease is found in a diverse range of frog populations across the world. The discovery sheds new light on some of the threats facing fragile frog populations, which are in decline worldwide.

The study, published in the Proceedings of the National Academy of Sciences journal, led by the University of Exeter and the Natural History Museum, describes the molecular methods used to test frog tadpoles for a newly identified infectious agent.

Tadpoles from six countries across three continents were tested for 'protists' -- single celled microbes with complex cells which store their DNA in a nucleus, like human cells. The previously unidentified parasite was present in tadpole livers in both tropical and temperate sites, and across all continents tested. The infectious agent was identified as a distant relative of Perkinsea sp., a marine parasites found in animals and algae.
