Cryptosporidium sp. in a free ranging house gecko (Hemidactylus turcicus) in Israel.

A house gecko, Hemidactylus turcicus, from an Israeli locality was found infected by Cryptosporidium sp. Infection was recovered in the anterior gut, upon examination by a transmission electron microscope. It comprised from 2.9 x 3.3 microns undivided and 2.6-3.3 x 3.8-3.9 microns dividing meronts, 1.9-2.3 x 2.0-2.6 microns young macrogamonts, and a 3.3 x 3.9 microns sporulated oocyst containing in cross section 4 sporozoites and a residuum. Oocyst dimensions were smaller and apparently not conspecific with the Cryptosporidium sp. reported from the introduced H. turcicus in Texas.
