 — No agglutination. 



Conclusions 



1. S. pullonim is pathogenic in varying degrees for the guinea fowl, pheasant, 

 pigeon, and sparrow. 



2. PuUorum disease in the adult guinea fowl and adult pheasant resembles 

 the disease in adult chickens. 



3. S. puUorum was recovered from eggs laid by artificially infected pheasants. 



4. The agglutinin production was slightly stimulated in pigeons even after 

 long exposures to the organism. 



5. Sparrows succumbed readily to artificial exposure of the organism. 



6. It appears that a sound eradication program might find it expedient to 

 recognize these aves as hosts, in addition to chickens, in combating pullorum 



AGGLUTININS IN CHICKS 



Rettger and Harvey (71) reported on one agglutination test which was made 

 with sera from chicks that had contracted the disease naturally. A slight reaction 

 was obtained in a 1 :50 dilution. They also observed the presence of agglutinins
