👉 Plicibuccinum is a type of bacterium that is commonly found in the mouth, particularly in the upper jaw and the tongue. It produces a unique type of acid known as plectin, which helps to protect the tooth enamel from damage caused by sugars and acids. Plicibuccinum can also be found in the gut flora, especially in children who have a weakened immune system or an overgrowth of bacteria called Clostridium difficile.
