Two sets of measurements were obtained. The first involved proglottides immediately posterior to the point of proglottis formation and proglottides at particular stages of development. For the second set, measurements were made of proglottides at certain positions in the worm, specifically the 20th, 100th and 200th proglottides, as counted from the posterior end of the worm. For proglottides at different stages in development, the width of a particular stage was greater in the later days of infection, while the length was almost constant. The length of newly-formed proglottides varied only slightly with time despite differences in the width and in the 3-fold increase in proglottis production that occurs between days 3 and 8 post-infection. The width of the 20th, 100th and 200th proglottides followed parallel growth curves that coincided with each other after an appropriate shift along the time axis. The more anterior the position of the proglottis, the greater was the width at the time of proglottis formation, and so its growth began later on the common growth curve. Growth in length of the 20th proglottis was at first faster than the 100th and 200th proglottides, but later slowed down to a level comparable with them, and the growth curves for the length of the three proglottides were very similar to each other. The rates of growth in the volume of the three proglottides were also estimated. The results are also discussed in relation to other approaches to the study of tapeworm growth and to factors that may be responsible for the growth patterns observed.<\/jats:p>","DOI":"10.1017\/s0031182000061096","type":"journal-article","created":{"date-parts":[[2009,6,5]],"date-time":"2009-06-05T14:50:07Z","timestamp":1244213407000},"page":"115-125","source":"Crossref","is-referenced-by-count":1,"title":["Growth of single proglottides during early adult development of <i>Hymenolepis nana<\/i>"],"prefix":"10.1017","volume":"99","author":[{"given":"H.","family":"Kumazawa","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I.","family":"Fairweather","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2009,4,6]]},"reference":[{"key":"S0031182000061096_ref017","doi-asserted-by":"publisher","DOI":"10.2307\/3281843"},{"key":"S0031182000061096_ref004","first-page":"105","article-title":"The effects of number and age of worms on development of primary and secondary infections with Hymenolepis diminuta in rats, and an investigation into the true nature of \u2018 premunition\u2019 in tapeworm infections","volume":"29","author":"Chandler","year":"1939","journal-title":"American Journal of Hygiene"},{"key":"S0031182000061096_ref013","doi-asserted-by":"publisher","DOI":"10.2307\/3277757"},{"key":"S0031182000061096_ref012","doi-asserted-by":"publisher","DOI":"10.1016\/S0014-4894(59)80005-9"},{"key":"S0031182000061096_ref020","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-12-058980-7.50010-5"},{"key":"S0031182000061096_ref023","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000071936"},{"key":"S0031182000061096_ref002","doi-asserted-by":"publisher","DOI":"10.1016\/0014-4894(58)90011-0"},{"key":"S0031182000061096_ref009","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000063083"},{"key":"S0031182000061096_ref021","first-page":"31","article-title":"Studies on the life history of the chicken tapeworm, Raillietina (Paroniella) kashiwarensis Sawada","volume":"8","author":"Sawada","year":"1959","journal-title":"Journal of Nara Gakugei University"},{"key":"S0031182000061096_ref001","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000048770"},{"key":"S0031182000061096_ref025","first-page":"179","article-title":"The development of organ systems in cestodes.
