114 Diseases of Poultry 



Marchoux ^ claims to have shown that the virus is not 

 transmitted through the feces but that it is probably trans- 

 mitted by some mite or tick. Experiments by others have 

 failed to prove definitely that it is transmitted by such 

 parasites. 



Several investigators have called attention to an apparent 

 relationship between this disease and rabies. Rosenthal 

 states that subdural inoculation of fowls with the virus of 

 this disease produces death with violent symptoms resem- 

 bling rabies. Schiffmann ^ states that in the cerebrum of 

 artificially inoculated geese certain corpuscles are found 

 which in some respects resemble the Negri bodies of rabies. 

 The two, however, are not identical. 



Control. — The methods for the control of this disease must 

 be similar to those of cholera. Sick birds must be isolated or 

 killed and great care taken that the blood of infected birds is 

 not spilled in the houses or yards.
