Abstract: Four Blastocystis isolates from cockroaches were established and these isolates were morphologically confirmed as Blastocystis organisms by light and/or electron microscopy. As these isolates were morphologically indistinguishable from Blastocystis isolated from other animals, phylogenetic analyses were conducted using their small subunit ribosomal RNA genes. A analyses of these sequences with previously reported ones that had been classified into nine Blastocystis clades indicated the presence of a new clade that comprised only Blastocystis organisms from cockroaches (clade X). A clade comprised of amphibian and reptilian Blastocystis organisms (clade IX) was located at the basal position of the Blastocystis tree together with the common ancestor of Proteromonas and Protoopalina, clade X emerged after the divergences of these two basal clades and its branching position was clearly supported by bootstrap analysis. © 2006 by the International Society of Protistologists.
