Pseudo parasites are free-living animals or parasites of other hosts acquired by a human individual and which may survive for some length of time therein. There are other reports of pseudo parasitism by myriapods in humans(Blanchard, 1898, 1902; Huber, 1902; Laurens, 1913-1919;Chamberlin, 1923; Garzia, 1938; Cavier, 1953; Ertek etal., 2004). In summaries in 1898 and 1902, Raphael Blanchard reported 40 confirmed cases of pseudo parasitism by millipedes and chilopods, most recovered alive from patients (Blanchard, 1898, 1902). By 1953 the total grew to 54 reported cases: 35 from the nasal cavities and frontal sinuses, three from “other parts” of the body (i.e. ear canal and urethra), and 16 from the gastrointestinal tract (Blanchard, 1898, 1902; Cham-berlin, 1923; Garzia, 1938; Cavier, 1953). In 2004 Erteket al. recovered the millipede Nopoiulus kochii from the intestine of a 14-year-old Turkish boy with a history of stomach aches and burning-throat sensations;he had found active millipedes in his mouth and feces(Ertek et al., 2004).Historically cases of pseudo parasitism have been initially regarded as delusions or misperceptions, often believed to have been fabricated. However, Cham-berlin in 1923 stated, “the number of carefully authenticated cases is now so large that there is no room whatever for doubt that myriapods may live for considerable periods, in some cases months, if not years, both in the aerial passages and in the alimentary tract, through the entire length of which they may pass unharmed
