Colonization Resistance
The phenomenon of colonization resistance refers to the prevention of the colonization of pathogenic bacteria in many areas of the human body, which in turn are colonized by naturally occurring and normally harmless bacteria.
Occurrence
The colonization with Escherichia coli prevents the spread of other germs in the intestinal flora . If, for example , they are killed during antibiotic therapy, other bacteria can spread. A classic clinical picture is pseudomembranous colitis , in which Clostridium difficile multiplies strongly.
The mucous membrane of the vagina secretes glucose in order to feed the vaginal flora , which mainly consists of the Döderlein bacteria . Colonization resistance also plays an important role in defense in other organs.
