Black-spotted pond frog as a new host for the renal coccidian genus (Alveolata: Apicomplexa).

Labbé, 1896 (Apicomplexa: Sarcocystidae) is a renal coccidium that infects anuran species. The genus consists of two species: , recorded from kl. and in Europe; and , recorded from in Japan. However, there have been no reports of in the other anurans in Japan. On June 2021, we examined a total of 58 adult frogs comprising 2  23 , 8 , 3 (Ranidae), 13 (Dicroglossidae), and 9 (Rhacophoridae) for infection by . Microscopic examination of kidney tissues revealed a high infection incidence of 47.8% (11/23) in but the other frog species were negative for . Morphological and molecular analyses using nuclear ribosomal and mitochondrial genes confirmed the infective species as This is a new host record for
