The parabasalids are a group of flagellated protists within the supergroup Excavata. Most of these eukaryotic organisms form a symbiotic relationship in animals. These include a variety of forms found in the intestines of termites and cockroaches, many of which have symbiotic bacteria that help them digest cellulose in woody plants.
Aug 7, 2010 · Other parabasalid species live in the intestines of some cockroaches and termites, enabling them to break down the cellulose in the dead plant material they eat. These symbiotic parabasalids in turn have symbiotic bacteria that aid in locomotion and cellulose breakdown.
Dec 31, 2016 · Parabasalians have evolved as symbionts of the animal digestive tract. Intestinal parabasalids generally cause little or no harm to their hosts (BonDurant and Honigberg 1994), with some pertinent possible exceptions (e.g., see below). A few species have moved to other areas of the body, where they are parasites.
Jan 9, 2012 · Most parabasalids inhabit the digestive tract of animal hosts as commensals, parasites, or symbionts. In particular, symbiotic parabasalids found in the gut of termites and wood-eating cockroaches play a central role in the digestion of cellulose .

What are parasitic parabasalids?
Diplomonads, parabasalids, and their relatives are mostly harmless commensals or beneficial symbionts found in the digestive tracts of both vertebrates and invertebrates. However, some species are pathogenic and cause various diseases of the intestine, urogenital tract, or other internal organs.

Jun 9, 2011 · Phylogenetic comparisons of parabasalids are typically based upon morphological characters and 18S ribosomal RNA gene sequence data (rDNA), while biochemical or molecular studies of parabasalids are limited to a few axenically cultivable parasites.
