PASSAGE OF TUBERCLE BACILLI FROM THE INTESTINE INTO THE CHYLE VESSELS AND THORACIC DUCT.

Abstract

The great infrequency of primary tuberculosis of the intestines does not harmonize at all well with the views that in a large number of cases tuberculosis is of alimentary origin. It will be recalled that Koch in his London address used this fact as an argument in favor of the harmlessness of milk from tuberculous cows. It would be difficult, however, to explain many cases of tuberculosis of the mesenteric lymph nodes, in which there may be no evident primary intestinal lesion, without assuming that the bacilli had entered from the intestinal lumen. Experiments, too, indicate that tubercle bacilli, as well as other bacteria, may pass through the normal intestinal wall. The most recent experiments are those of Nicolas and Descos,1 who fed fasting dogs large quantities of tubercle bacilli in soup. Some three hours later the animals were killed and several cubic centimeters of chyle secured for further
