Genetic diversity of Entamoeba: Novel ribosomal lineages from cockroaches.

ABSTRACT: Our current taxonomic perspective on Entamoeba is largely based on small-subunit ribosomal RNA genes (SSU rDNA) from Entamoeba species identified in vertebrate hosts with minor exceptions such as E. moshkovskii from sewage water and E. marina from marine sediment. Other Entamoeba species have also been morphologically identified and described from non-vertebrate species such as insects; however, their genetic diversity remains unknown. In order to further disclose the diversity of the genus, we investigated Entamoeba spp. in the intestines of three cockroach species: Periplaneta americana, Blaptica dubia, and Gromphadorhina oblongonota. We obtained 134 Entamoeba SSU rDNA sequences from 186 cockroaches by direct nested PCR using the DNA extracts of intestines from cockroaches, followed by s
