Prevalence of antibodies to soluble antigen of Epstein-Barr virus-producing cells (P3HR-1) in the sera of hamadryas baboons of the high lymphoma incidence stock.
Soluble antigen of P3HR-1 cells (SA-P3HR-1) was identified in indirect double immunodiffusion enhanced with tannic acid using serum of a nasopharyngeal carcinoma patient containing high-titer antibodies to Epstein-Barr virus (EBV) antigens. SA-P3HR-1 was nonidentical to soluble antigen of Raji cells. Human and baboon sera containing antibodies to all the known antigen of EBV and HVP respectively were anti-SA-3HR-1-positive. Human and baboon sera containing antibodies to all the known antigens of EBV and herpesvirus Papio (HVP) were also anti-SA-P3HR-1-negative. Prevalence of anti-SA-P3HR-1 was very high in two groups of the high-lymphoma incidence stock of hamadryas baboons of the Sukhumi monkey colony. 54% (15 of 28) and 38% (13 of 34) of clinically lymphomatous and clinical normal monkeys, respectively, were anti-SA-P3HR-1-positive.. Only 1 of 30 normal baboons studied, living in the forest and having no contacts with the baboons in the main stock of the Sukhumi monkey colony, was anti-SA-P3HR-1-positive (3%).
