I called WSU this morning and talked with the doctor and the histology report came back and she has sent me the report via mail. Gertie did have Merak's Disease, it wasn't present in all the nerves/organs (not in the liver, and another spot she mentioned) but it was found in the brain and in other spots. I will post the lab results when I get them in the mail. We talked about vaccinating the remainder of the flock and she said that it could possibly help -- research is still out on that. I am going to call the state vet now and see about vaccinating the rest of the birds. The vaccination is Serum 3 and she said Serum 1 can cause the disease to present itself in the birds that already have it but they don't use that anymore, Serum 3 will not cause the presentation of the disease (I think I am stating this correctly). I purchased all but 2 of the birds at local feed stores, I will be calling all of them to let them know. 2 were purchased from the same farm -- but earlier when our 1 bird died I contacted her about the possibility of Marek's and she said she didn't have it in her flocks. Hard to figure the source...doesn't matter too much I guess. We have it -- and now we have to deal with it.
