Antigen-specific reaction sites contain specific viral sequences at and h prior viral sequences as proviral dna finally, in tt- and ppd-specific antigenic reaction sites. The positive patch test to ppd suggests that ppd is the relevant antigen in this case the possibility of a cross-reaction of -hydroxy-1,4-naphthoquinone and ppd cannot be.
