Symptoms ia Cats, Course. 567 



In one case Mueller observed, on the side of the neck, a deep ulcer with a 

 sinuous border and torpid granulating base. The neighboring lymph glands were 

 enlarged. Cadiot observed a fistula of the withers and chronic arthritis of tuberculous 

 origin. 



Acute miliary tuberculosis runs a rapid course attended 

 with symptoms of an acute infectious disease (Petit). Accord- 

 ing to Cadiot tuberculosis in dogs may also assume a septicemic 

 character. 



Tuberculosis of Cats. The clinical appearance of this dis- 

 ease is as yet not well known. Since the pathologico-anatomical 

 changes are very much alike, the clinical symptoms are probably 

 similar also. 



Thus, Lellmann observed the following in two angora cats : 

 Excessive emaciation and anemia, anemic heart bruits, labored 

 breathing and accelerated, weak pulse ; in one case the abdominal 

 cavity contained a milky fluid with tubercle bacilli, there was 

 also pronounced leucocytosis ; in the other case there was dull- 

 ness upon percussion on both sides of the chest and bronchial 

 breathing; a tumor was present in the abdominal cavity, under 

 the spinal column. Hobday & Belcher, in a case of general 

 tuberculosis, found the subparotideal, the submaxillary and the 

 prescapular lymph glands enlarged and purulent. Finally, 

 Petit & Coquot described a case of tuberculosis of the skin 

 on the face in which the bridge of the nose, one cheek and the 

 corresponding lower eyelid were transformed into one ulcerat- 

 ing surface. 



Course. Tuberculosis always has an insidious beginning, 

 develops in a chronic manner and usually preserves its chronic 

 character until its fatal termination. The development of the 

 disease is usually so slow that years may elapse before morbid 

 symptoms point to its presence and when observed in mature 

 animals it is usually found to have had its beginning in early 

 youth. The tuberculous process, in its slow and chronic course, 

 usually does not exert a harmful influence on the general con- 

 dition of the animal until after the lapse of considerable time, 

 which explains that animals in well nourished, or prime condi- 

 tion and in apparently perfect health may frequently exhibit 

 extensive tuberculous changes when slaughtered. This is par- 

 ticularly true,, in a general way, with regard to tuberculosis 

 of cattle and especially in cases of pearl disease of the serous 

 membranes. In many cases this form of tuberculosis, even when 

 far advanced, does not in the least affect the general condition 

 of the animals. In other animals, especially in young animals, 

 the disease usually runs a less insidious course. In young pigs 

 that are infected by milk from tuberculous cows the course 

 of the disease may be so rapid that the progressive changes 

 may be noted from week to week. 



In the course of this naturally chronic affection, especially 

 in its later stages, acute exacerbations occur from time to time,
