A total of 339 chicken, turkey, and pheasant flocks was tested during the 

 1956-57 testing season. Among 1,178.338 samples tested, 0.01 percent 

 was positive, which is a definite decrease over the percentage (0.08) positive 

 in the previous season. Four flocks revealed infection, and at the close of 

 the season all but one were classified as negative. Pullorum infection was 

 detected in one flock that was negative the previous season. It is encourag- 

 ing to note that 99.87 percent of all birds tested are in noureacting flocks.
