An average of 4.9 tapeworms were discovered on day 7 of a low-abundance H. diminuta infection of rats of race WAG alb. After 11 months, the mean was only relatively slightly tower at 3.6. These means represent 97.1 and 71.4% of the 5 cysticercoids supplied. In turn, 7 days and 11 months after rats were supplied with 110 cysticercoids, the respective percentages were 85.1 and 56.0. All 7- and 12-day tapeworms from the low-abundance and crowded infrapopulations were characterized by the presence of a terminal proglottid of lingulate shape, in which the excretory canals joined. In contrast, older (48-day and 11-month-old) worms showed typical apolysis of gravid proglottids. There were no reports of the destrobilation of tapeworms, and the relatively large number of tapeworms persisting 11 months into the infection is particularly noteworthy. The results point to the lack of any rapid rejection of tapeworms of the kind characterized in many other studies on H. diminuta.
