In view of the special environment in which intestinal parasite worms live, the intestinal bacteria found in them would have properties peculiar to them as compared with those of the bacteria found in the intestines of other. animals leading different modes of life. A study of these properties, especially a comparison of them with those of the intestinal bacteria found in the host, would serve to solve one of the important problems in clarifying the significance of the intestinal bacteria and would also contribute towards the clarification of physiological function of the intestinal parasite worms. The author performed experiments on the intestinal bacteria of ascaris, using 25 ascarides suilla and 20 ascarides lumbricoides living on different hosts; culture of their intestinal canal as well as both aerobic and anaerobic cultures of the content of. small intestine or the stools of the hosts was undertaken in order to investigate the total number, species and distribution of bacteria. Following are the results of the investigation : 1) The species and distribution of intestinal bacteria found in ascaris suilla were more or less similar to those of the bacteria found in that part of the intestine of the host where it lived. However, there existed no close relation numerically, the number of the intestinal bacteria found in ascaris suilla being smaller than that of the bacteria found in that part of the intestine of thehost. 2) The intestinal bacteria found in ascaris lumbricoides were of the same species as those found in the stool of the host, but there existed no close correlation between the two in distribution. The number of the former was much smaller than that of the latter. 3) Of all the species of the intestinal bacteria found in ascaris, the coli group topped the list, followed by the enterococcus group, the L. acidophilous and obligate anaerobic bacteria in that order. 4) Of the coli group, the Escherichia coli accounted for the majority. There were also found some aerobacter, the Escherichia freundii, the Bethesda-Ballerap group, the Arizona group and the Proteus. 5) The number of obligate anaerobic bacteria found was comparatively small and the Bacteroides accounted for the majority of them. The main species weere B. Fujikawa I, B. peloton and L. bifidus. 6) The increase in the number of bacteria found in the intestine of ascaris paralleled the increase in the number of bacteria found in the intestine of ascaris paralleled the increase in the length of the period during which the worm had been fed.
