296 PUBLIC HEALTH BACTERIOLOGY 



tuberculosis of all kinds in swine, the bovine virus was 

 found in 50 cases, the human in 3, the avian in 5, and a 

 mixed avian and bovine virus in i case. 



In 33 of these cases the tuberculosis was generalized, 

 and in 32 of these the infection was bovine, the other 

 being the one of mixed bovine and avian infection. The 

 other 26 cases showed local tuberculosis. 



CONCLUSIONS : All three types of bacilli are capable of 

 infecting the pig, but the bovine bacillus is the one much 

 most frequently found, and in many instances it produces 

 a severe and generalized disease. 



Tuberculosis in Horses. In most cases of tuberculosis 

 in horses it is primarily an affection of the glands and 

 organs in connection with the alimentary tract ; the 

 abdominal organs chiefly. This was so in the five cases 

 investigated. In all, bacilli were recovered which were of 

 the bovine type culturally ; and three of them also had 

 the bovine virulence. The other two had diminished 

 virulence for the test animals in the test doses ; passage 

 experiments raised this to that of the bovine virus. 



Tuberculosis in other Animals. In a gnu which 

 died from generalized tuberculosis in the London Zoological 

 Gardens, the human virus only was found. 



In an antelope, killed when ill, in the same Gardens, 

 where it had been many years in captivity, extensive 

 tuberculosis, with cavities in the lungs, was found. The 

 human virus alone was isolated. 



In a rhesus monkey, killed when ill at the quarantine 

 station at Isleworth, tuberculosis of the lungs was found, 

 and some elsewhere. Here too only the human virus 

 could be got. 



A chimpanzee died of acute miliary tuberculosis at the 

 quarantine station. The tuberculosis started from the 

 alimentary tract, and from a mesenteric gland the human 

 virus was obtained. 



A cat, suffering from naturally acquired tuberculosis, 

 was investigated. A mesenteric gland gave a bacillus of 

 the bovine type in growth and virulence. 



Tuberculosis in Birds. In g cases investigated 

 (3 fowls, 3 pheasants, i pigeon, i demoiselle crane, I 

 Senegal touracou) of tuberculosis occurring naturally in
