How is Campylobacteriosis diagnosed?
Many kinds of infections can cause diarrhea and the other symptoms associated with campylobacteriosis. Doctors can look for bacterial causes of diarrhea by asking a laboratory to culture a sample of stool from an ill person. Microbiology laboratories now routinely perform culture procedures on stool specimens that are specifically designed to promote the growth and identification of Campylobacter jejuni and the other species of Campylobacter.
Many persons submit samples for culturing after they have started antibiotics, which may make it even more difficult for a lab to grow Campylobacter. Blood cultures are often not performed and in most cases the blood stream is not infected.
