Phylogenetic characterization of Isospora jaracimrmani oocysts from a veiled chameleon (family Chamaeleonidae; Chamaeleo calyptratus ) reared at a zoo in Ishikawa, Japan

[摘要] Oocysts of Isospora sp. were detected in the feces of a veiled chameleon (family Chamaeleonidae; Chamaeleo calyptratus ) kept at a zoo in Ishikawa, Japan. Phylogenetic analysis placed the sequence in the cluster of Isospora spp. isolated from reptiles. Based on a comparison of morphological data of ten previously reported Isospora species from the Chamaeleonidae family, this isolate was morphologically similar to I. jaracimrmani , which has been considered to be a virulent species. This case study suggests the possibility that species of Isospora might not always cause disease because the animal that shed these oocysts showed no symptoms for more than two months.
