PARASITES AND DISEASES OF POULTRY 
symptoms of disease remove at once to some iso- 
lated place, feed very lightly on mostly green food, 
administer a remedy, and be guided further by 
the persistency of the attack. Medicines and drugs 
prepared for human beings can often be used to 
advantage for fowls, as the effect is much the same, 
but the dose should, of course, be lessened for 
fowls. 
Roup is one of the most contagious and destruc- 
tive diseases among fowls, and is especially preva- 
lent in the fall and winter months. It 
is a contagious catarrhal disease, char- 
acterized by running at the eyes and nostrils, puffed 
eyes, and swollen head; later, mouth and throat 
become filled with foul-smelling mucous, or some- 
times cheesy matter. The disease is caused by its 
own special germ, but the predisposing causes are 
usually dampness or drafts, while crowding, filth, 
and almost any neglect or mismanagement may 
also be a factor. Colds and catarrhal disorders 
often develop into roup if neglected. Diphtheria 
or diphtheritic roup is similar to ordinary roup, 
but perhaps a little worse. 
Roup is a very difficult disease to cure, and per- 
haps the easiest and most reliable way is to use one 
of the advertised roup cures. With this disease, in 
addition to isolating all afflicted birds, establish a 
quarantine for all suspects. If a patent roup cure 
is administered, use peroxide of hydrogen once a
