During the 1955-56 testing season a total of 353 chicken, Inrkcy, and 

 pheasanJ flocks was tested. Among 1,178,167 sampk's tested, 0.08 percent 

 was found to be positive, which is a definile decrease over the percentage 

 (0.12) positive in the previous season. Six flocks revealed infection, and 

 at the close of the season all hut two were classified as negative. Pulloruni 

 infection was not detected in any flocks that were negative the previous 

 season. It is encouraging to note that 99.40 percent of all birds tested are 

 in nonreactinc flocks.
