ABSTRACT
To investigate the ecology of dengue and Japanese encephalitis (JE) viruses in the forest in Asia, a seroepidemiological survey was carried out on 358 Southeast Asian cynomolgus (Macaca iris), 33 Indian bonnet (Macaca radiata) and 37 Japanese (Macaca fuscata) monkey sera by a plaque reduction neutralization test. The results indicated that Southeast Asian monkeys were naturally infected with these viruses but the frequency of antibody to them varied considerably according to the geographical origin of the monkeys. The frequency of antibody to one or more types of dengue virus were 87.2, 49.5, 34.3, 34.2 and 14.9% in Malaysian, Vietnamese, Cambodian, Indonesian and Filipino cynomolgus monkey sera, respectively. None of the Indian bonnet monkey sera neutralized type 1 dengue virus which was the only virus type examined with this monkey species. Monkey sera collected in Japan where dengue virus infection had not been known since 1944 did not significantly neutralize dengue viruses. JE virus antibody was detected at 29.7, 9.0, 8.6, 2.7, 1.4 and 0% in Japanese, Cambodian, Vietnamese, Indonesian, Filipino and Malaysian monkey sera respectively.
