New evolutionary lineages, unexpected diversity, and host specificity in the parabasalid genus Tetratrichomonas

Abstract

We studied morphological and molecular polymorphism of 53 Tetratrichomonas isolates obtained from amphibian, reptilian, mammalian hosts, and from a slug with the aid of protargol staining and analyses of ITSI-5.8S rRNA-ITS2, SSU rRNA, and tubulin genes
