To muddy the waters still further, CPn is such a difficult thing to find that even with a lumbar puncture, it might not be seen. You stand a better chance at Vanderbilt, though.
I didn't have one and I probably would have tested negative anyway, because nobody over here seems capable of doing it. I was sero-tested for CPn and borrelia, nearly negative for one and absolutely negative for the other, so..................
Roy, I am so glad that you showed some posts to Dr. Sriram: it must have cheered him up no end! I know from correspondence with David that he has been getting very despondent of late.
