👉 Aporrhaoids are a group of bacteria that are commonly found in the gut, particularly in the small intestine. They have a unique ability to produce a chemical called arginine, which helps with digestion and can also be used as an enzyme. Aporrhaoids are part of a larger group known as the Bacteroides species, which includes other types of bacteria like Vibrio cholerae, Staphylococcus aureus, and Streptococcus pneumoniae.
