Don't fully understand your response, Mary.

A great many clinically diagnosed animals returned negative tests, animals with vesicles and lesions. Pirbright say the tests are almost 100% accurate so the conclusion must be those animals were healthy.

Doesn't make a lot of sense does it? Unless of course the tests are unreliable which is what I have been banging on about for the last 18 months.

Kind regards,
Bill.
