PARASITOSIS OF A TRAVELLER RETURNING FROM A TROPICAL ZONE
The authors present an image composition in which, the lower right is a 400X fresh stool examination, where an elongated egg of about 80x45 μm without vitelline membrane, with a very irregular and mamelonated thin covering and cytoplasmic mass with amorphous and refracting granules is showed, being identified as an infertile egg of Ascaris lumbricoides. In the upper part of the image, an adult nematode of slightly pinkish color, about 20 cm long, 4 mm wide and with a slightly curved caudal end (left lower part) is presented, being identified as an adult male of Ascaris lumbricoides.
