Re: [Killietalk] Survivability of *Glugea*

[Barry Cooper <bjc3 at centurytel_net>]

I don't have any controlled observations, but I can tell you that when I 
had to move from NY to Oregon, there was a period of over a year in which 
my tanks were dry, due to my moving back and forth between those locations. 
My involvement in studying this infection was due to the fact that I had 
"acquired" it in my fishroom. I have never seen it again since moving to 
Oregon, which suggests to me that prolonged drying will kill the spores. 
The problem is that I don't know just how long is required. Dr. Ed Noga at 
NC State might have more objective information.
