kind were found in the intestine or caeca. Sections of the gut examined 

 by Dr Fantham showed numerous coccidia in all stages of multiplication in 

 the epithelial cells. The second chick (B. 2. Hatched at the same time 

 and treated in the same way) was also ill when received, and was killed 

 and examined immediately. In this case a few colonies of Bacillus coli were 

 obtained from the liver cultures. No worms were found, and the condition 

 of the intestine was the same as in the first chick. A third older chick 

 (four months) which had been fed on coccidia three weeks previously was 

 also killed and examined. A few streptothrices developed on the cultures 

 from the lungs, but those from the other organs remained sterile. Neither 

 worms nor coccidia were found in the intestine or caeca. 



These observations seem to indicate that intestinal Coccidiosis may so 

 injure the gut that bacteria are allowed to pass into the circulation. This 

 conclusion is supported by eight observations on young rabbits suffering 

 from naturally acquired Coccidiosis of the intestine, the results of which are 

 given in the following Table.

 Young Rabbits suffering from Coccidiosis.

The mesenteric glands yielded intestinal bacteria in all cases. The 

 cultures from the other organs, including the liver, yielded no intestinal 

 bacteria when the small intestine was normal, or showed merely a trace of 

 Coccidiosis. On the other hand, when the small intestine showed well-marked 

 Coccidiosis Bacillus coli or Bacillus enteritidis was always present in the 

 liver, and sometimes in the other organs. Thus the existence of Coccidiosis
