ERADICATION OF PULLORUM DISEASE 

 IN MASSACHUSETTS 



1928-1929 

 By W. R. Hinshaw, E. F. Sanders, and G. L. Dunlap 



One of the most successful seasons in the history of the eradication 

 program was closed on March 1, 1929. Service was given to every 

 applicant, with the exception of one who had an outstanding account. 

 Much of this success was due to the efforts of the State and County 

 Extension Services in encouraging earl,v filing of applications. Because 

 of the large number of applications received previous to September 1, 1928, 

 it was possible to route the blood collectors more effectively, and poultry- 

 men in turn received l)etter service than in j^revious seasons. 



For their excellent cooperation during the past testing season, we wish 

 at this time to express appreciation to the poultrymen, the State and 

 County Extension Services, Mr. Oliver S. Flint, Manager, M.A.C.F.B., 

 the respective offices of administration, and the members of the Depart- 

 ment of Veterinary Science. 



Name of Disease Changed 



At the second annual Conference of I>al)oratory Workers held at New 

 Haven, Connecticut, May 1, 2, 3, 1929, it was unanimously voted to 

 accept the suggestion of Dr. Leo F. Rettger, Yale University, to change 

 the name of bacillary white diarrhea to "pullorum disease". It was 

 further agreed that all laboratories represented at the conference (twelve 

 laboratories located in United States and Canada) should make the pro- 

 posed change in all publications and forms used as soon as possible. 

 Therefore, in this report and on all new forms issued, the name pullorum 

 disease will be substituted for Salmonella pullorum infection and for 

 bacillary white diarrhea,. 



This is a most desirable substitution and will prevent confusion with 

 the many other forms of diarrheas in chicks, and will be a specific name for 

 the disease in adults. Furthermore, it will have the advantage over the 

 name Salmonella pullorum infection, adopted by this laboratory a year 

 ago, because of its brevity. There is little doubt but that "pullorum 

 disease" will become universally accepted, and poultrymen are urged to 

 use the term on all occasions when referring to the disease either in 

 adults or in chicks. 



Summary of Service Rendered 



A service which has nt)t been rendered before is that of free autopsy 

 and bacteriological examination of reactors from flocks which have pre- 

 viously been non-reacting. In tiiese cases, the reactions often are 

 questionable, and to give the poultryman the benefit of the doubt a nega- 

 tive report is issued if Salmonella palluruin^ the causative organism, is not
