[QUOTE="Lucky_P, post: 1603457, member: 12607"] IDK... I've occasionally argued with myself that, if I had a herd known to have endemic anaplasmosis... one might be better off testing and removing all seronegative animals... they're the ones that are gonna get sick and possibly die. The seropositive carriers will not. I'm not saying that this is a good plan... just something I've turned over in my mind on occasion. Commercial herd... I'd probably just recommend vaccination. Seedstock operation is a bit different, as more buyers are becoming aware of the issue and requiring test-negative status on purchases. Vaccinated animals will be seropositive, and unless you run PCR on whole blood samples, you can't differentiate between persistently-infected carriers and animals that just have an antibody titer to the vaccine.
