Bacteria produce disease in one of two general ways; some bacteria damage the cells and tissues of the infected organism directly by breaking down the cells for food, other bacteria release toxins (poisons) that travel throughout the body interfering with the normal activity of the host. Pathogens.
Most bacterial skin diseases are caused by staphylococci or staph. This bacteria causes the majority of the bacterial skin diseases. The staph bacteria which cause the diseases live on humans. In fact, as much as 40% of humans are carriers of the type of staph which causes diseases.ost bacterial skin diseases are caused by staphylococci or staph.
