Distribution of Human T-Cell Leukemia Virus Type- I (HTLV-I) Family Among Non-Human Primates
The seroepidemiological surveys of human T-cell leukemia virus type-I (HTLV-I) family were conducted among free-ranging Japanese monkeys, Asian and African non-human primates kept in cages and sampled in the field study. Seropositive animals to HTLV-I family in nature belonged to macaques originated from various localities in Asia. Grivet monkeys and Anubis baboons including those hybrid offspring between Anubis and Hamadryas were seropositive for HTLV-I family in Africa. As a result, HTLV-I family was proved to be widespread on Asian and African Continent. Thus the wide geographic and phylogenetic distribution of HTLV-I family in nature among various species of catarrhines suggests that the introduction of this virus family into primates occurred in ancient times and the HTLV-I family was considered as a common retrovirus among catarrhines.
