Abstract Kudoa septempunctata (Myxozoa: Multivalvulida) infects the muscles of olive flounder (Paralichthys olivaceus, Paralichthyidae) in the form of spores. To investigate the effect of K. septempunctata spores in mammals, adult BALB/c mice were fed with spores of K. septempunctata genotype ST3 (1.35 × 105 to 1.35 × 108 spores/mouse). After ingestion of spores, the mice remained clinically normal during the 24-h observation period. No spores were found in any tissue examined by histopathological screening. Quantitative PCR screening of the K. septempunctata 18S rDNA gene revealed that the K. septempunctata spores were detected only in the stool samples from the spore-fed groups. Collectively, these findings suggest that K. septempunctata spores are excreted in faeces and do not affect the gastrointestinal tract of adult mice.
