Detection of Neospora caninum (Toxoplasmatidae) in wild small mamals from Thailand

Abstract

The presence of Neospora caninum Dubey, Carpenter, Speer, Topper et Uggla, 1988 in small mammals (i.e. murid rodents, Erinaceomorpha, Eulipotyphla and Scadentia) was explored for first time in South-East Asia. A total of 192 individuals from six localities across Thailand were analysed. A general prevalence of N. caninum of 22% was observed, with some variation among localities (5-36%). Four main types of habitat were included and rodents trapped in dry-land habitat (17 positive among 41 individuals) were more likely to be infected with N. caninum than those from other habitats (forest, rain-fed land and settlement). Rodent species identity and individual rodent weight had no influence on individual infection. Our results provided the first data on the presence of N. caninum in rodents in South-East Asia and first report of N. caninum in the order Scadentia.
