Seroepizootiology of the herpesvirus Papio (HVP) infection in healthy baboons (Papio hamadryas) of high- and low-lymphoma risk populations.
Seroepizootiology of Herpesvirus Papio (HVP) infection was studied in three groups of healthy hamadryas baboons (Papio hamadryas): the main Sukhumi (high-lymphoma) stock, forest Sukhumi (lymphoma-free) stock and newly imported wild animals. The prevalence to HVP infection, as judged by anti-VCA-HVP positivity, was approximately the same in both Sukhumi stocks (86% and 90% respectively) and it was significantly lower in the pooled group of newly imported baboons. It is interesting that prevalence of HVP infection in the different independent groups varied markedly (35-79%). Geometric mean titers of positives in all groups were approximately the same. The prevalence of HVP infection was age-dependent. It increased during the first years of life reaching the maximum (about 100%) at the age of 5 years being stable up to the age of 18 years and "decreased" at very old ages (over 18 years). The prevalence of HVP infection in newly imported baboons increased with age up to 71% in a group of the "oldest" monkeys and did not plateau. No significant sex differences in anti-HVP titers were found. Anti-EA-HVP-positive (with one exception) and anti-HUPNA-positive animals were found only in the main Sukhumi stock. Thus, "serologic activity" against HVP infection was the highest in the ligh-lymphoma stock.
