To date however, the effect of an intestinal adult tapeworm on leucocyte migration from the pronephros has not been ascertained. The individual points for each proglottid number represent the measurements for the individual tapeworms. The actual number of tapeworms used for each set of measurements is indicated in the results section. The length of the tapeworms varied from 3 to 40 mm. Cross-sections of 176 proglottids were obtained from randomly selected sections of strobilae from 12 tapeworms. Transmission to humans occurs when eggs of the tapeworm, excreted by the final hosts (usually foxes but also dogs, wolves and cats), are ingested accidentally. Copepods were starved the day before experimental infection with tapeworms. The rats were infected on different days and using different batches of cysticercoids, and the mean number of tapeworms recovered was 26. Previous studies indicate that the interaction between the tapeworm and its copepod intermediate host is characterized by a high degree of specificity. Since some tapeworms had fewer proglottids than others, there are fewer data points for the higher proglottid numbers. Despite much interest in molecular phylogeny, molecular studies dealing with families and genera of tapeworms are scarce. The bottom graph summarizes the relationship between the lengths and widths of individual proglottids (237 proglottids from 21 tapeworms). Half of the copepods received a mixed exposure, using mixtures of the same three tapeworm sibships to infect 12 copepods on each 24-well plate. Indeed, increased mortality would be maladaptive for the tapeworms, because only live copepods are ingested by the subsequent host. These examples are from corpora and from sources on the web.
