Escherichia coli (E. coli) bacteria normally live in the intestines of people and animals. Most E. coli are harmless and actually are an important part of a healthy human intestinal tract. However, some E. coli are pathogenic, meaning they can cause illness, either diarrhea or illness outside of the intestinal tract.
Staph bacteria are frequently present in healthy humans. Areas where the bacteria can be found include the sebaceous (sweat) glands, nose, and other skin areas.Because of this colonization of healthy people, it is almost impossible to prevent contact with the bacteria.reas where the bacteria can be found include the sebaceous (sweat) glands, nose, and other skin areas.
