The status of distribution of heat resistant Clostridium perfringens in the feces from healthy persons was investigated by using the anti-sera to Hobbs' type 1 through 13. The resistant organisms were detected in about half of the fecal specimens; The isolated organisms were serologically typable by Hobbs' criteria in many cases. Among 21 fecal specimens yielding the resistant organisms, 7 contained exclusively untypable organisms. Two or more serological types were often found from a single specimen. Out of 18 strains isolated from 14 specimens, 7 were classified as type 13, 4 type 1, 2 type 4 and one each type 2, 3, 5, 9 or 10. The resistant organisms were detected at all the examinations made during the period of 7 months or even longer in some persons. Howeverin, some persons. the types of the isolated organisms often changed from time to time not only in the intermittent but also in the permanent carriers.
