162 Diseases of Poultry 



4. Keep watch of the flock so that any new cases may be 

 isolated at once. 



5. Burn or bury deep all birds that die. 



The disease is amenable to treatment but this treatment 

 must be individual and requires a great deal of time. It 

 must be continued once or twice a day for quite a long time. 

 It is, therefore, very expensive and consequently imprac- 

 ticable for ordinary stock. Moreover birds apparently cured 

 are likely to become the source of infection for later outbreaks. 



In the case of valuable show birds treatment may perhaps 

 be advisable. 



The treatment recommended for catarrh or cold may be 

 used effectively in early stages of roup. 



Harrison and Streit ^ give the following methods of treating 

 roup : 



" The germs of roup are not very resistant ; they can 

 easily be destroyed when present in cultures, or somewhere 

 outside the animal ; but in the animal tissue, they are very 

 diflficult to kill, because they penetrate into the tissue ; and 

 unless this too is killed, the germs continue living for a 

 long time." 



" Roup may be cured by remedies, if the treatment is careful 

 and judicious. ... If the eyes and nose are attacked, they 

 have to be carefully washed, at least twice a day, with an 

 antiseptic solution, such as 2 per cent boracic acid in a 

 decoction of chamomile flowers, or ^ per cent solution of 

 corrosive sublimate. Thus the micro-organisms are killed 

 or at least, the diseased products which are discharged are 

 removed, and the irritation caused by them ; also the trans- 

 formation into large cheesy masses is prevented. 



"We had chickens badly affected with roup of the eyes, 

 which were cured with boracic acid and chamomile. On
