Koch did not give rise to doubts about the identity of the causative agent of tuberculosis in humans, cattle and birds, because in terms of their attitude to coloring substances and the conditioning of pathomorphological changes, both behaved the same way. But already in 1889, Rivolta expressed the opinion that the tube rod of birds in its morphological and biological properties differs significantly from the human VC. The opinion of Rivolta was confirmed in 1890 by Maffucia, and R. At the congress in Berlin, Koch recognized the avian tuberculosis bacillus as a separate, although very close type to the VC of human tuberculosis. Thus arose the doctrine of the duality of tuberculosis, the difference between avian and human tuberculosis. This dualistic teaching has found experienced defenders in the person of Straus and Gammalei. The main arguments were as follows: the tbc bacilli of birds give a more abundant culture and a wetter one; they grow well at t 43. They are pathogenic for chickens and not pathogenic for dogs. They kill rabbits and guinea pigs without, however, pathomorphological changes caused by VC being detected in their organs.</p>Kazan Medical archiveКазанский медицинский архив
