ROUP AND "ROUPY" COLDS 



SYMPTOMS WHICH WILL AID DIAGNOSIS— CAUSES 

 AND CONDITIONS— BEST MEANS OF PREVEN- 

 TION—SIMPLE AND EFFECTIVE TREATMENT 



P. T. WOODS, M. D. 



IN actual every day experiences diseases are not as easy to recognize as 

 one might be led to believe by reading about them in books. It is 

 often difficult to tell just which symptoms belong to the disease, and 

 which belong to some other cause or condition. It is not always pos- 

 sible to say where one disease leaves off and another begins, and it is quite 

 likely that we may meet more than one disease at the same time in the same 

 subject. During the past nine years I have had an opportunity to observe 

 and treat roup and "roupy" diseases in large flocks of fowls under many con- 

 ditions. I have not had the time nor the equipment to make a microsco- 

 pical search for the germ or germs (the bacteriological) work properly be- 

 longs to the laboratories of our experiment stations), but I have had ample 

 opportunity to .see and treat "roupy" diseases. 



The name roup has been given to all poultry ailments having the common 

 symptoms of "frothy eyes and running discharge from nostrils." All 

 "colds" may have these symptoms, and every cold is not roup. There are 

 three diseases of a roupy nature which are not easily differentiated — ^roup 

 (or contagious catarrh), diphtheria and influenza. I think that the latter is 

 a distinct disease with a special germ of its own, but am not prepared to say 

 positively that this is so. Many contend that contagious catarrh and diph- 

 theria are caused by the same germ, and in view of the close relationship 

 between these diseases this may be so. In such case, roup (contagious ca- 

 tarrh) and diphtheria may be the same disease, the symptoms varying only 

 with the virulence of the germ and the conditions; but although the diseases 

 have many things in common, and tend to merge readily from one into the 

 other, I prefer (until the laboratory experiments settle the matter) to con- 

 sider the diseases as two distinct plagues. 



ROUP 



The term roup has been applied to nearly all poultry diseases accom- 

 panied by the symptoms described as "frothy eyes and running discharge 

 from nostrils." All "colds" may have these symptoms, and every cold 

 is not roup.
