a
Presence (+) or absence (−) of FeLV-B proviral DNA as detected by Southern blot analysis or polymerase chain reaction (PCR) amplification.
b
Tumor tissues were analyzed from animals with lymphoma. Mesenteric lymph node, bone marrow, thymus or kidney was examined from animals 903, 905, 1223 or 942, respectively. Spleen was examined from animals 924, 1002 and 936.
