 DIARRHOEA 



19254926 



By P. E. BRANSFIELD 



This bulletin gives a detailed record of the 1925-1926 season's work on the 

 control and eradication of bacillaiy white diarrhoea in adult birds. During 

 the season 67,919 birds were tested; only 2.31 per cent of infection was found. 

 One hundred and twenty-four flocks, representing 33,61.'5 birds, were found to 

 be free from the disease, as compared with 79 flocks and 25,390 birds the 

 preceding year. These results indicate that the beginning of the end is near 

 in the elimination of this disease from the breeding flocks in Massachusetts.
