here , we have analysed felv dna in tissues of 22 spf cats that had been inoculated with the feline aids strain ( felv-faids ) and we find two classes of viral dna -- a monotypic common form which is detectable in bone marrow regardless of disease state , and variant forms , recognizable by restriction site differences , whose appearance correlates with onset of disease symptoms and persists throughout the course of the disease .
