Mr Patterson,
Your email about dead tadpoles in a garden pond was forewarded to me.
I have worked extensively on amphibian deformities, die-offs and
declines for the past 5-6 yrs at the Dept of Interior's National
Wildlife Health Center.
The die-off of tadpoles that you describe almost certainly is NOT due
to chytrid fungus infection. The disease-causing chytrid fungus kills
frogs and toads only AFTER metamorphosis is complete. Chytrid
infection of tadpoles is a mild, self-limited infection of just the
oral disc; chytrid infection has never been proven to cause death of
tadpoles.
Chytrid infection of amphibians has been detected in Georgia from one
or more sites along the Savanna River and from bullfrog tadpoles
within the boundaries of Ft Stewart.
Because you do not report the species of tadpole that was dying and
the signs ("symptoms") in dying tadpoles, it is not possible to guess
what was killing your amphibians.
The National Wildlife Health Center performs diagnostic examinations
at no charge on free-living wildlife involved in disease outbreaks and
die-offs.
However, we cannot accept pets, zoo animals and other captive wildlife
for diagnostic examinations; normally, such captive animals are
referred to the state's veterinary college or the animal (or fish)
diagnostic lab within each state's department of agriculture.
