Sick pond syndrome
Sick pond syndrome Amphibians who have so far survived for over 250
million years on Earth are getting sick. The cause of the sharp
decline in amphibian populations across the globe is the topic of
an international summit on amphibian health to be hosted by the San
Diego Zoo. It will be the first time that 60 herpetologists,
epidemiologists, virologists, pathologists, bacteriologists, and
neuroimmunologists have come together to talk. Using their
different skills, the scientists are planning to work together in
an attempt to discover the reasons for the decline in amphibians
worldwide. One of the theories which will be considered is that
environmental changes may be affecting amphibians' immune systems,
leaving them easy prey to numerous bacterial and viral
infections. 25 JULY 1998, P. 21
