SCANNING ELECTRON-MICROSCOPY OF LAGOCHILASCARIS-MINOR LEIPER, 1909 (NEMATODA, ASCARIDIDAE)

Lagochilascaris minor Leiper, 1909 is a parasitic nematode with its bi ological cycle still unknown, even though it was found in humans, dome stic and silvatic animals. Adult worms, collected by surgical drainage from a human patient from the State of Para, Brazil, were micrographe d using a scanning electron microscope. Morphological aspects of males and females such as cephalic structures, caudal papillae and cuticula r patterns were analyzed and compared with the previous descriptions a dding new data for the identification of this species.
