PSEUDOMEMBRANOUS (CROUPOUS) PHARYNGITIS. 



False membranes not due to a common microbian cause. Accessory 

 causes in solipeds ; caustics, smoke infection. Lesions ; Congestion, ne- 

 crosis : croupous exudate, extending to patches on bowels and bronchia ; 

 kidney infarctions ; blood altered. Symptoms : fever, dyspnoea, mucous 

 rattle in throat, swelling, painful, difficult deglutition, yellow or cyanotic 

 mucosae, pinched face, weakness, prostration. Duration. Diagnosis. Treat- 

 ment, as for catarrhal pharyngitis with antiseptics by inhalation and elect- 

 uary. Iron. 



Pharyngites attended by the formation of false membranes are met 

 with in all the domestic animals and may be grouped together 

 as a special class. The collection of these in one group, however, 

 must not be taken to imply that all of these, as met with in the 

 different animals have the same pathology, and are due to one 

 invariable cause. Above all it must not be inferred that they are 

 identical with the malignant diphtheria of the human being. 

 The bacillus diphtheriae hominis isolated by Klebs in 1883, and 

 proved pathogenic by Lbffler in 1884, has not been successfully 

 inoculated upon any of the larger domestic animals, and has not 

 been found in any of the casual pseudomembranous pharyngites 

 of these animals. The common feature of the group is to be 

 found in the formation of the false membrane, and the fact that a 

 given disease is placed in the group must not be held to apply to 

 any special character, of microbian origin, nor communicability 

 by infection.
