The controversy begins with diagnosis, even though the method used is considered to be the gold standard. A bacterial count greater than 10 x 5 colony-forming units CFUs/Ml in a culture of jejunal aspirate are used. However, this methods limitations in terms of difficulty of obtaining samples, its invasive character, and problems of contamination and maintaining anaerobic conditions have led to considerable dispute about its use 42.
