Detection of Trypanosoma spp. in Bandicota indica from the Thai-Myanmar border area, Mae Sot District Tak Province, Thailand
Journal Title: Asian Pacific Journal of Tropical Medicine - Year 2019, Vol 12, Issue 10
Abstract
Objective: To investigate the prevalence of trypanosome infection and their phylogeny in Bandicota indica rats from the cadmium-contaminated area of Mae Sot and the Myanmar border. Methods: Blood samples were taken from 100 animals, and parasite infection was examined by light microscopy observation and polymerase chain reaction (PCR) studies. Results: Trypanosoma spp. infection was found in 20% of the thin blood smear samples. PCR showed positive 623 bp DNA bands in 21 samples (21%). The sequencing analysis showed that all of the samples (100%) had the Trypanasoma lewisi 18S ribosomal RNA gene. Phylogenetic analysis confirmed that these 16 isolates of Trypanosoma spp. were closely related to Trypanasoma lewisi. Conclusions: Molecular detection using PCR is as effective as conventional light microscopy analysis. This study confirms that trypanosomal infection in rodents is still high; therefore, fleas as their vectors need to be controlled in order to prevent transmission to humans.
