DESCRIPTIONS OF PATHOGENIC BACTERIA. 165 



the German Schweineseuche also exists in 

 America is still somewhat doubtful ; in Ger- 

 many the Scandinavian-American swine-plague 

 has been observed, at least sporadically. The 

 disease manifests itself especially as a severe 

 affection of the intestine. 



A third and related group of germs dis- 

 covered by Reitsch and Joubert, are morpho- 

 logically similar, but the bacteria are actively 

 motile, coagulate milk with production of acid, 

 and form both indol and phenol in peptone 

 solutions. The disease they cause was ob- 

 served in Southern France among swine in- 

 troduced from Algeria. Eberth found similar 

 organisms in cases of ferret disease and spon- 

 taneous rabbit septicaemia. The difference 

 between this and the first group lies in the 

 motility of the bacteria, and in the fact that 

 the swine suffer more from enteritis, as in the 

 Schweinepest. 



Two years ago a disease of swine was rife in 

 North Germany, the chief symptom of which 

 was a diphtheritic affection of the large intes- 

 tine. According to Deupser, motile bacteria 

 were always present. Unfortunately the ex-
