organism isolated, for which the name Bacillus lymphangiticus is proposed,

The anatomical and histological expression of increased resistance toward 

 tuberculosis in cattle following the intravenous injection of human and 

 attenuated bovine tubercle bacilli, T. Smith (Jour, Med. Research, 32 (1915), 

 No. 3, pp. Jf55-Jf69, pJs. If ) . — " The intravenous injection of tubercle bacilli of 

 bovine type into calves, following preliminary injections of bacilli of human or 

 attenuated bovine type causes a heightened resistance which manifests itself by a 

 shifting of the lesions from the parenchyma of the lungs, i. e., the alveolar walls, 

 to the bronchioles serving lobules or portions thereof. The affected lobules are 

 subpleural. 



"The disease is chronic and progressive to a certain degree at least. It 

 develops as a peribronchial inflammation in which lymphoid or round cells pre- 

 dominate. This may break through the wall of the bronchus, fill the lumen, 

 cause collapse, aspiration of ingrowing cell masses with tubercle bacilli, and 

 subsequent caseation of the collapsed territory. Teins and arteries in the im- 

 mediate neighborhood of affected bronchioles are not invaded. 



" The beginning of tuberculous changes in the wall of the minute bronchi is 

 not in itself proof that the bacilli are air-borne, nor does it prove that inlialed 

 bacilli have penetrated directly the mucosa of the minute bronchi. Localiza- 

 tion depends very materially upon states of resistance of the host, or, what Is 

 equivalent, on the degree of virulence of the tubercle bacilli. The type of cell 

 reaction is the same in the udder as In the lungs. Endothelloid and giant cells 

 seem to be much more numerous in those cases whose acquired resistance is 

 lowest. 



'• The development of tuberculosis in the apical lobes in man is best ac- 

 counted for by the less active aeration and loss active lymph current. Rib 

 pressure may contribute toward fixing the bacilli. Bacilli, deposited either from 

 the air or the blood in other lobes, are either destroyeil or promptly carried by 

 the lymph current to the lymph nodes, where they are gradually destroyed. The 

 phenomenon of phthisis in man is strong evidence that tlie human being 

 possesses a relatively high degree of resistance to the tubercle bacillus. This 

 inference from comparative pathology has been abundantly proved in the past 

 by autopsy records."
