TURKEYS 



Should turkey flocks be tested for pullorum disease? Yes. Turkey flocks 

 used for breeding purposes should be tested annually because the infection be- 

 haves similarly to that 

 in the chicken. React- 

 ing turkeys should be 

 removed promptly 

 from the flock. 



Is the whole blood 

 test effective in de- 

 tecting infected tur- 

 keys? No. Only the 

 macroscopic tube ag- 

 glutination method 

 should be employed in 

 testing turkeys for pul- 

 lorum disease. 



What serum antigen 

 dilution should be used 

 for • diagnostic pur- 

 poses? The 1 :25 dilu- 

 tion has given the most 

 satisfactory results. A 

 low dilution is neces- 

 sary in detecting in- 

 fected turkeys, be- 

 cause their sera react 

 only in very low dilu- 

 tions. Low-dilution 

 reactors are observed 

 more frequently 

 among infected tur- 

 keys than among in- 

 fected chickens. 



Are other measures 

 besides testing neces- 

 sary in establishing 

 and maintaining pullo- 

 r u m-f ree turkey 

 flocks? Yes. • The 

 measures listed under 

 Question 94 are appli- 

 cable to turkeys.

Numerous misshapen, discolored cystic ova and normal 

 ova were present. Ovarian cultures yielded S. pullorum.
