The GI tract is also known as the gut. Trillions of bacteria and tiny organisms, called flora, live there. In fact, the flora make up about 60% of our feces. Three main types of flora live in the gut:
How long it takes for a staph skin infection to heal depends on the type of infection and whether a person gets treatment for it. A boil, for example, may take 10 to 20 days to heal without treatment, but treatment may speed up this process. Most styes, on the other hand, go away on their own within several days.
The answer to how long does food poisoning last and how long does it take for symptoms to show also depends upon where the poison came from. If the tainted food contained staph, the symptoms can begin within one hour of eating. If the problem came from campylobacter, the symptoms might not show up for 10 days or more.
