A cyst-forming coccidian with large geographical range infecting forest and commensal rodents: Sarcocystis muricoelognathis sp. nov.

Background: The geographic distribution and host-parasite interaction networks of Sarcocystis spp. in small mammals in eastern Asia remain incompletely known.

Methods: Experimental infections, morphological and molecular characterizations were used for discrimination of a new Sarcocystis species isolated from colubrid snakes and small mammals collected in Thailand, Borneo and China.

Description of sp. nov. from treeshrews (, ) in northern Borneo with annotations on the utility of COI and 18S rDNA sequences for species delineation.

sp. nov. was discovered in histological sections of striated musculature of treeshrews (, .
