Trichonympha

Trichonympha are complex, single-celled organisms known as zooflagellate protozoans that belong to the order Hypermastigida. These organisms are typically found in the digestive systems of termites and cockroaches, where they live symbiotically.1

In termites, Trichonympha plays a crucial role in digestion. Termites primarily consume cellulose from wood and other plant materials, which they cannot digest on their own. The symbiotic protozoans, like Trichonympha, reside in the termite's hindgut and secrete enzymes that break down cellulose into simpler sugars that the termite can absorb. Without these protozoans, termites would be unable to extract nutrients from their diet and would starve. The protozoans are essential for the termite's survival, sometimes making up half of the host's total weight.21
