“…During the course of this survey none of the group A patients suffered from any form of gastroenteritis or diarrhoeal illness and the high numbers of C. perfringens carried by these patients was probably a reflexion of the normal 286 M. F. STRINGER AND OTHERS carriage situation for some elderly institutionalized or hospitalized patients. These results therefore support the findings of Yamagishi et al (1971) and Sutton (1966). If a cluster of cases of diarrhoea occur in such patients it is not unreasonable, following the laboratory examination of faecal specimens, to assume that C. perfringens food poisoning is responsible.…”

“…Faecal carriage of C. perfringens has been studied primarily in relation to its diagnostic significance in the investigation of suspected outbreaks of food-borne disease, and it was soon realized that it was important to estimate the numbers of C. perfringens in faecal specimens. Sutton (1966) showed that healthy people usually carried between 103 and 104 organisms/g whereas patients in outbreaks tended to carry 105-106/g. In 1976, Yamagishi et al found that the numbers of C. perfringens in the faeces of some healthy adults in a Japanese Home for the Aged were consistently of the order of 107-109/g.…”

SUMMARYThe numbers and serotypes of Clostridium perfringens present in the faeces of three groups of hospital patients and young healthy laboratory workers were examined in studies lasting between 10 and 13 weeks.In one hospital some long-stay geriatric patients carried relatively high numbers of C. perfringens (> 107/g) most of the time and it was not unusual in any one week for the majority of these patients to carry the same serotype(s). However, the numbers of C. perfringens in the faeces of young long-stay patients in the same hospital were in the range of 103-104/g and carriage of common serotypes was not observed. These results were similar to the findings with the young laboratory workers. This investigation indicates that two of the laboratory criteria often used in the investigation of C. perfringens food poisoning, i.e. faecal counts of > 105 C. perfringens/g and patients carrying the same serological type need to be interpreted with caution with suspected outbreaks involving some groups of geriatric long-stay hospital patients.
