Abstract
A coprological survey was made to assess the spectrum of helminth parasites in Mithum and other co-existing wild livestock in Bhutan and neighbouring Arunachal Pradesh (India). Nematodes with direct life cycle were found to be most predominant helminth infection among these animals. Cestodes and trematodes were poorly represented as their occurrence is primarily determined by the presence of the Invertebrate intermediate hosts in the locality of the final host.
