This is a thorough study of the bone marrow and blood of 133 patients seen by the author in the hospital and his private practice in Helsinki. Of these, twenty-two (eleven males and eleven females) were considered normal. There were 111 with tapeworms, of whom eleven were infected with Taenia saginata and 100 with Diphyllobothrium latum. Of the latter, twelve had anemia (pernicious). Of the eighty-eight carriers, sixty-four were females and twenty-four males; of the patients with anemia, seven were females and five males. Of the patients infected with Taenia saginata there were two males and nine females. The author was able to study many of the cases before and after treatment. The monograph has many tables showing the results of studies on blood and bone marrow (sternal puncture).
In general, Tötterman concludes that the type of erythropoiesis in carriers of the broad tapeworm is normoblastic with a slight reduction
