Kexsel: Amoibac of Culture Rats and Mice

INCIDENCE OF INFECTION OF AMOEBAE IN 

 RATS AND MICE 



During the investigation 80 mice and 288 rats have been examined 

 for amoebae. As stained slides have be^n made in only 45 of the 

 positive cases found, the exact species of amoebae has been determined 

 only in these 45 rats and mice. The other examinations were made for 

 the purpose of procuring animals for infection experiments and were 

 studied only in iodine-eosin. The data in the first table serve merely 

 to differentiate between amoebae of the genus Cauncilmania and the 

 genus Endamoeba.
