[Three cases of mycobacteriosis with gastrointestinal localization]

The authors present three patients having primary microbacterial infections which involved the gastrointestinal tract. A short survey of the clinical features and the difficulties arriving at definitive diagnosis is given. They discuss the differential diagnostic problems in each case--without an unequivocal bacterial findings--on the basis of histologyc data and of therapeutic response which ultimately proved the mycobacterial nature of the infection.
