BACILLARY WHITE DIARRHEA OF FOWLS 219 
Prevention. Bacillary white diarrhea is introduced into new dis- 
tricts by the indiscriminate buying of eggs for hatching and the pur- 
chase of day old chicks from infected farms. Female chicks that sur- 
vive the attack and become adults often become spreaders of the 
organism through their eggs. Investigations by Jones and Rettger 
show that not all the eggs of such fowls are infected but that now and 
then they are and chicks hatched from such eggs are not only infected 
themselves but also spread the infection to others in the same brood. 
The prevention of the disease consists, therefore, in the detection and 
removal of adults that are spreaders, the segregation of the chicks 
until they have reached the age of four days and the thorough disin- 
fection of the brooders, runways and feeding and drinking utensils. 
Jones suggested the very practical method of segregating the eggs 
near the close of the incubation period into isolated groups of two or 
three so that if any egg was infected and a chick hatched from it the 
germs could not spread to others. This is a very serious disease but 
one that can be readily controlled if precautionary measures are taken 
in time. 
Specific treatment. No satisfactory biological treatment has been 
discovered.
