Pyxie chytrid

I doubt there's a Pyxie that doesn't carry this, at least in captivity. I don't see why they wouldn't be susceptible to it but the thinking is that they're less likely to succumb to it since they've been exposed to it for so long (naturally).

that's what I was thinking.
Thanks John

I was looking into this, I have a couple of African Bullfrogs, some of the earliest known specimens of frogs with chytrid fungus are African clawed toads from South Africa collected and preserved in the 1930's. This must be well before the ancestors of the captive African Bullfrogs around today were collected. Not all of them would have been from the same region but it seems likely that given the speed of spread in regions newly exposed to the disease that most would have been exposed. If they were survivors, and as immune responses tend to have a genetic component, it would be likely that they have at least some degree of tolerance.

Many believe that old world species have had long term exposure to to this disease and are much less vulnerable to it than new world species.
