Bacteria is the wife of Unhygienix. She is one of the inner circle of village wives. She is quiet and easy-going, but doesn't hesitate to say exactly what she thinks. She helps her husband run his shop, selling fish of dubious quality, and is unperturbed by the bizarre uses to which they are sometimes put. They have two sons (whose names have not been mentioned) – one with blonde hair in Asterix in Corsica, and the other with red hair in Asterix and the Secret Weapon.
