Again if all things stated are true, I believe they are the carriers & even if he went another 12 weeks fallow, & did TTM again by the book, I'd bet we would read this same unfortunate result. The only true way to eradicate this is to start over, in my opinion.
If TTM was executed correctly, there's no way for a fish to be a carrier. TTM eliminates the possibility of reinfection by removing the cyst stage. With each transfer, you only have the possibility of trophonts that are already on the fish, and these are eliminated by the second transfer typically.
