I have only seen symptoms in younger birds under 5 months. I have never seen an adult bird show symptoms. I don't know for sure that it's always Mareks, but when a single bird suddenly he problems walking in a group of young birds I assume that's what it is.
That goes along with the information I have. I think that diagnostic labs see Mareks so much, they tend to render off the cuff, incorrect diagnoses without actual testing. A tumor to them means Mareks when, as a vet I always consulted told me, a bacterial infection can send bacteria all through the bloodstream, resulting in many small tumors and have zero to do with Marek's.
