To the Editor.—
The writer of the letter titled "Snakes in the Grass, Or, the Worm Turns On" (221:917, 1972) has provided your readers with a bit of rib-tickling rhetoric, but more than a modicum of misinformation. One must take exception not only to the doses of pyrvinium pamoate for Enterobius vermicularis infection, the use of furazolidin for Dientamoeba fragilis infection, and the homeopathic dose of diiodohydroxyquin, but also to the assumption that raw marihuana was the cause of this kaleidoscopic array of parasitic infections.Such a panoramic succession of single or combined infections is not unusual in the experience of myself and my associates among male homosexuals. Given the multiplicity and versatility of sexual contacts in this group, it is not surprising that fecaloral transmission of a variety of infectious agents occurs frequently. The source is much more likely to be venereal than vegetable.
