👉 Oligotrema is a type of bacteria that lives in the gut of certain animals, primarily humans, but can also be found in aquatic environments. This organism is characterized by its small size and is often referred to as "the little bacterium" due to its ability to survive in low-oxygen conditions. Oligotrema is also known for its ability to colonize and thrive in the gut of other animals, potentially contributing to their overall health and well-being.
