Prevalence of Infection of Endoparasites and Its Intensity in Small Mammals' Liver Captured from Irrigated Rice Crop Area and Villages

摘要

The research was conducted during November 2018 - January 2019 in two provinces namely West Java and Yogyakarta. The aim of the study was to study the prevalence of infection of endoparasites inhabiting the liver of small mammals and its intensity. Two different habitats, irrigated rice crop area and two villages closed each other were chosen as trapping sites. Sampling was conducted by performing two methods i.e. trapping using snap trap and LTBS (Linear Trap Barrier System) continually. The snap traps (75 pieces) and 30 bubu traps were set around the small mammals' habitat. A regular monitoring of the trapping was conducted in the next morning. Animals captured were identified and dissected to observe endoparasites infecting their digestive organs. The total number of samples captured from the two provincial trapping location was 423 individuals. There were four species identified namely Rattus argentiventer, Rattus tanezumi, Suncus murinus, and Bandicota indica. Two species of endoparasites were found in the liver of Taenia taeniaeformis and Capillaria hepatica. Prevalence of infection for both endoparasites was higher in animals captured from irrigated rice crop area compared to the village area. The prevalence of infection for T. taeniaeformis was 36.7% and C. hepatica was 35.25% from the animals captured in the irrigated rice crop. Their intensity of infection was varied from light, medium to heavy level. Meanwhile, the prevalence of infection for the same endoparasites from the animals captured from the village was lesser. Prevalence of infection for T. taeniaeformis infected animals captured in the two villages was 12.31% and 17.6%, respectively. The same situation was also similar for the C. hepatica which had their prevalence of 0.7% and 0.8% for the same samples captured from the same habitats. Their intensity was also lower than what we found in animals captured from the irrigated rice crop area.
