Did I mention that the adult birds would probably be stressed or 
immunocompromised if contracting the polyoma? I think the term for catching 
the virus (or having the antibody) is "seroconversion". It's what happens 
after the antibody is there that is the question. Everyone assumes that if 
the antibody is at all present a bird is a carrier. No one seemes to 
understand that an adult CAN shrug off the problem. They don't understand the 
seroconvert and/or
become immune part of the process. Thanks for bringing this out. I've never 
talked to Dr Ritchie, but to Jack Gaskins, the virologist at Univ of Fla Vet 
school working on grants also on this problem of avian viruses. I try to 
repeat it as best I can but I'm not infallible... I think I did read that 
article you
mentioned. Good to see people get the word out.
The vaccine is out. it is however prohibitively expensive, about $50 a hit, 
especially for the large breeder. Even IF all the birds bred, that still 
doesn't mean we have sales for all of them.
Dr Gaskins is supposed to come out and test everything I have when we both 
have time. Part of his research.
Thanks,
Barbara
