Pathogenic Bacteria

There are three groups of gut bacteria, and one of them refers to Pathogenic Bacteria that are harmful to the human body. These bacteria appear in Episodes 22 and 23, though their specific species are unidentified. The Pathogenic Bacteria recruit many Hiyorimikin found in the gut and launch an attack from within. They assault General Cells with toxins, but when Lactic Acid Bacteria appear, the Hiyorimikin switch sides. In the end, the Pathogenic Bacteria are wiped out by Neutrophils.
