622 CHRONIC INFECTIOUS DISEASES 



prominent with diarrhea during the latter stages. Rapid 

 emaciation is generally followed by death in a short time. 



Diagnosis. As tuberculosis is not very common in dogs 

 and cats, and the symptoms not particularly characteristic, 

 a diagnosis is not often made during life. The history of the 

 case and its chronicity might lead one to suspect it. Tuber- 

 culin (0.15 to 0.20) might be used subcutaneously. The 

 reaction is more prompt but the test is not so reliable as in 

 large animals. 



Prognosis. Unfavorable. 



Treatment. In advanced cases no treatment should be 

 attempted. During the early stages good nutritious food, 

 and tonics are best. Inhalations 'of creolin vapor are recom- 

 mendablc. 



GLANDERS. 



In dogs and cats glanders is not very common. It is occa- 

 sionally observed among carnivora fed meat or organs from 

 horses affected with glanders. In zoological gardens glanders 

 may be enzootic among meat eating animals, especially 

 when horse meat is fed. Glanders usually assumes an acute 

 form in these animals. The early symptoms are those of an 

 intense inflammation of the mucous membrane of the nasal 

 passages, larynx, trachea, and the conjunctiva. In a short 

 time (two to five days) appears a greenish-gray or blood- 

 stained secretion from the eyes and nose. The respirations 

 are labored on account of the intense congestion and swell- 

 ing of the respiratory mucous membrane. The symptoms 

 rapidly become aggravated, the tissues about the head 

 become swollen, nodules appear at different points in the 

 skin, which open and form irregular shaped ulcers. Diarrhea 

 is a prominent symptom. The animal becomes emaciated, 

 and succumbs in the course of eight to fourteen days. When 

 such symptoms occur, the animal should be isolated so that 

 further spread of the disease is controlled. Thorough dis- 

 infection of the premises, and proper disposition of the 

 cadavers are very important.
