Abstract

The study was conducted to determine the helminth parasites of bats. Chiroptera, representing 9 species belonging to 3 families comprised mainly of Cynopterus brachyotis (31 out of 96 bats or 32.3%), were collected from 4 sites at the University of the Philippines Los Baños, Laguna. The bats were euthanized and the entire gastrointestinal tract was examined for helminths. Parasites recovered were fixed in 70% ethyl alcohol. Trematodes and cestodes were stained in Semichon?s acetocarmine stain and mounted in Canada balsam. The nematodes, unstained, were cleared in lactophenol for viewing under the microscope. From the 96 bats examined, 25or 26.04% had one or more helminths. Helminths recovered were Plagiorchis from Scotophiluskuhlii,Aonchotheca from Philetorbrachypterus, Cynopterusbrachyotis and S. kuhlii, and a hymenolepidid cestode from P. brachypterus. The corresponding prevalence rates of these helminths were 17.7%, 16.7% and 6.2%. The possible life cycles and significance of these helminths in bats and humans were briefly discussed.
