ABSTRACT
This study was undertaken to examine further the natural infection of poikilothermic animals e.g. turtles, to Japanese encephalitis (JE) virus. Plasma samples from 75 soft-shelled fresh water turtles (Trionyx sinensis Wiegman) from China were examined in virus neutralization (VN) and hemagglutination inhibition (HAI) tests for the presence of specific antibody. The total incidence of antibody detected by either test to a titer of 10 or greater was 89% while 77% and 60% were positive by VN and HAI tests, respectively. Forty-one per cent were jointly positive by both tests. Mean HAI and VN titers were similar and showed no obvious differences between spring/summer and autumn/winter seasons. The HAI reactivity was associated with a 7S component for both seasons. The significance of this inhibition in the serology of poikilothermic hosts and the possible behaviour of T. sinensis in the natural history of JE virus is briefly considered.
