192 DISEASES OF THE INTESTINES 



lish the diagnosis. The finding of the Bacterium asthenise 

 in several of the birds will confirm the diagnosis. 



Prognosis.— Owing to the infectious nature of the disease, 

 the chronic course, and the pathological changes which have 

 taken place in the duodenal mucosa, the prognosis is unfavor- 

 able. Where the disease has reached an advanced stage it is 

 advisable to destroy the bird and thoroughly disinfect the 

 premises. 



Treatment.— Medical.— Small doses of laxative, castor oil 

 (1.0-4.0) or calomel (0.01-0.05) should be given. 



As a stomachic and tonic iron sulphate may be given in 

 the drinking water (1-1000). 



The aromatic seeds (fennel, coriander, anise) may be used 

 once or twice daily with the food to stimulate the secretions 

 of the stomach and intestines. 



Prevention.— The healthy birds should be separated from 

 the sick ones at once. All parts of the houses (roosts, floors, 

 etc.) should be thoroughly cleaned and disinfected with a 

 carbolic acid solution (5 per cent.).
