A. GENERAL 



L Salmonella puUoruin infection (Bacillary White Diarrhea) is a common 

 infectious disease of chicks and adult fowl, causing severe loss in this State. 



2. The disease may be transmitted from generation to generation by car- 

 riers, principally through eggs laid by diseased hens. 



3. Carriers (reactors) may be detected by means of a laboratory test 

 called the agglutination test. In infected flocks several tests in;iy be neces- 

 sary to eradicate the disease from tiie flock. 



4. The entire flock including males, pullets, and hens should be tested eacli 

 year. Several tests per season on infected flocks will hasten eradication. 

 After a flock is once free from the disease an annual 100 per cent flock test 

 is recommended to insure freedom.
