Pseudomembranous Pharyngitis in Swine. 65 



Lesions do not differ materially from those seen in the calf. 

 The inflammation and pseudomembranous exudate may extend 

 as far as the trachea and bronchia in which case the indications of 

 death by asphyxia are clearly marked. 



Treatment is the same as for the calf. Tepid drinks slightly 

 acidified with muriatic acid, or the addition to the drinking water 

 of one pound of sulphate of soda to every fifty sheep has been 

 especially recommended. Fumigation with sulphurous acid or 

 chlorine is easy of application in flocks. As alternatives for ad- 

 dition to the water may be named hyposulphite or bisulphite of 

 soda, borax, carbolic acid, or spirits of turpentine. For treat- 

 ment individually swabbing the throat with antiseptics and dilute 

 caustics, electuaries and hot poultices to the throat may be tried. 



PSUEDOMEMBRANOUS PHARYNGITIS IN SWINE. 



Prevalence in herds, in close pens, and in young. Relation to swine 

 plague and hog cholera. Symptoms : sore throat, prostration, hoarse 

 cough, yellowish discharge with shreds of false membrane, pellicles on 

 mouth, fauces, tonsils. Diagnosis from swine plague. Treatment : Isola- 

 tion, disinfection, antisepsis to throat, febrifuges. 



This has long been recognized as a contagious affection, oc- 

 curring especially where the animals were kept in herds and too 

 often in close and filthy pens. These are more liable in youth 

 than in maturity, partly no doubt because the older animals have 

 already suffered and attained to an immunity. Modern observa- 

 tion has shown that pharyngitis with formation of false mem- 

 branes is especially common in swine plague, and the present 

 tendency is to refer all such cases to that category. It is however 

 altogether probable that the occurrence of local irritation with 

 the addition of an irritant or septic microbe altogether distinct 

 from those of swine plague or hog cholera, gives rise at times to 

 this exudative angina. Certain it is that septic poisoning with 

 the food is not at all uncommon in the hog, in the absence of 

 these infectious diseases. 



The symptoms are those of severe sore throat with profound
