👉 Tubicolix, also known as tubicolous worms or fecal pellets, is a type of protozoan that lives in the gut of certain animals and humans, particularly those with an intestinal bacteria called Clostridium difficile. These worms produce a mucus-like substance called faeces, which helps to absorb nutrients from food. This process is crucial for the survival of these organisms, as it aids digestion and absorption of essential vitamins and minerals.
