Note 171 — ON PARASITES IN GENERAL. (continued 4)
Reading edition
Notwithstanding the progress made during the last decades, the ova of helminthes and more particularly of trematodes, have been mistaken for Coccidia. Thus Poschinger (Zool. Anz., 1819, ix, p. 471) and Gebhard (Virchow’s Arch., 1897, No. 147, p. 536) mistook the ova of Distoma turgidum, Brds., for Coccidia. Podwyssotzki (Centralbl. f. allg. Path., 1890, i, p. 135) made a similar error with the ova (and vitelline sacs) of a species of Prosthogonimus (Distoma ovatum of the authors); von Willach (Arch. f. wiss. u. prakt. Thierheilk., 1892, xviii, p. 242) mistook the ova of a nematode for Coccidia.
