190 Infectious Papulous Inflainmation of the Mouth of Cattle. 



Diagnosis. The white or yellowish spots which are formed 

 together with the symptoms of stomatitis and the vesicles on 

 the margins of the lips furnish a very characteristic picture. 

 The presence of vesicles on the margins of the lips, the inflam- 

 matory halo around the lips, and the shallow ulcerations dis- 

 tinguish the disease from thrush (Soor), while the al)sence of 

 vesicles on the mucosa differentiates it from vesicular stom- 

 atitis. In severe cases of aphthous stomatitis, ulcerative stom- 

 atitis may be thought of; but as such severe cases usually occur 

 side by side with mild cases, the true nature of the disease 

 can readily be recognized. 



Treatment. In consideration of the very contagious char- 

 acter of the disease, healthy young animals and their mothers 

 must be separated from the sick lambs. The healthy animals 

 should lie kept under observation and all new cases of infection 

 are to be separated promptly. The pens must be subjected to a 

 thorough cleaning' and disinfection. Since the sick animals can, 

 in consequence of the painful character of the disease, not easily 

 suck or not at all, they should be fed with milk obtained from 

 their mothers by milking ; or if they are old enough to be weaned 

 they may receive some other suitable liquid food. 



The local treatment consists in frequent washing of the 

 mouth with disinfectant fluid, for instance, 4% boracic acid 

 solution, 3-4% solution of chlorate of potash, 1-2% solution of 

 sulphate of copper. These solutions should be introduced into 

 the buccal cavity with a syringe or an irrigator.

(b ) Infectious Papulous Inflammation of the Mouth of Cattle. 

 Stomatitis papulosa. 



(Gutartige Maulseuche [German] [Ostertag & Bugge] ; Stom- 

 atitis follicularis [Hess] ; Stomatitis papillaris [Degive].) 



Contagious papulous inflammation of the mouth of cattle 

 is an acute specific disease caused by an ultramicroscopic micro- 

 organism ; it is afebrile and is characterized by the appearance 

 of flat papules on the buccal mucosa and often also on the 

 muzzle. 



Since the papules on the buccal mucosa have a certain similarity 

 in their structure with the aphthae of man, it is proper to consider the 

 disease in this place. 



Historical. The etiology of the disease which made its appearance, 

 epizootically, among Bavarian steers in the stockyards of Berlin (Tiarks) 

 has been cleared up by Ostertag & Bugge (1905), who also showed that
