How is it possible for strict anaerobic bacteria to cause a disease in humans? Strict anaerobe pathogens produce toxins that damage the host cells. There are parts of the human body where oxygen is absent. Strict anaerobes can hide from the immune system rather well. Strict anaerobes can break down the oxygen creating an anaerobic environment in the body.
