[Intra-dental route of experimental tuberculosis infection].

A total of 13 dogs weighing 13-15 kg were infected by intra-dental route with the tuberculosis mycobacterium strain H37R in a dose of 0.5 ml in the 5th dilution according to a turbidity standard. Two dogs were given intravenously the same dose of tuberculosis mycobacteria and they formed a control group. The observation varied from 10 days to 5 months. It was found tuberculosis development in intradental contamination could be attended by generalized specific affection of the viscera and development of a "minor" tuberculosis inflammation in the peridental tissues.
