The study was divided in 2 trials including in total 22 litters (254 piglets). The first trial included 4 litters (where standard procedures practiced routinely on the farm piglets were applied) and the piglets were followed coprologically from farrowing until 2 weeks after weaning. The sows of those litters were also examined at various intervals before and after farrowing. The second trial included the application of 3 different management procedures: (A) standard farm hygiene and management procedures, (B) standard farm hygiene and management procedures+the first piglets found to excrete<jats:italic>I. suis<\/jats:italic>oocysts in each pen were removed from the pen, and (C) reduced cleaning. Each procedure was studied in 2 litters. This was replicated 3 times to yield a total of 18 litters. The results suggested that (i) the sow does not play an important role in transmission of<jats:italic>I. suis<\/jats:italic>in the farrowing pen; (ii) in natural infections, both the age of the piglet age at onset of oocyst excretion and the oocyst excretion patterns may vary considerably; (iii) the course of oocyst excretion or development of diarrhoea is related to the time of initial infection and (iii) piglets, which are heavy at birth, are more prone to acquire<jats:italic>I. suis<\/jats:italic>infection. Moreover, it was demonstrated that cleaning could be an effective means of restricting the spread of the parasite within the litter and thus the development of diarrhoea.<\/jats:p>","DOI":"10.1017\/s0031182007003952","type":"journal-article","created":{"date-parts":[[2007,11,19]],"date-time":"2007-11-19T11:39:59Z","timestamp":1195472399000},"page":"395-405","source":"Crossref","is-referenced-by-count":20,"title":["Population dynamics and intra-litter transmission patterns of<i>Isospora suis<\/i>in suckling piglets under on-farm conditions"],"prefix":"10.1017","volume":"135","author":[{"given":"S.","family":"SOTIRAKI","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"ROEPSTORFF","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.\u00a0P.","family":"NIELSEN","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"MADDOX-HYTTEL","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"EN\u00f8E","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"BOES","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.\u00a0D.","family":"MURRELL","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.\u00a0M.","family":"THAMSBORG","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2007,11,19]]},"reference":[{"key":"S0031182007003952_ref035","doi-asserted-by":"publisher","DOI":"10.1177\/030098588001700109"},{"key":"S0031182007003952_ref032","first-page":"317","article-title":"Coccidiosis in swine: dose and age response to Isospora suis","volume":"46","author":"Stuart","year":"1982","journal-title":"Canadian Journal of Comparative Medicine"},{"key":"S0031182007003952_ref11a","doi-asserted-by":"publisher","DOI":"10.1007\/PL00008515"},{"key":"S0031182007003952_ref005","first-page":"643","article-title":"Control of Isospora suis-induced coccidiosis on a swine farm","volume":"46","author":"Ernst","year":"1985","journal-title":"American Journal of Veterinary Research"},{"key":"S0031182007003952_ref003","doi-asserted-by":"publisher","DOI":"10.1007\/s004360100378"},{"key":"S0031182007003952_ref027","doi-asserted-by":"publisher","DOI":"10.1136\/vr.107.7.156"},{"key":"S0031182007003952_ref001","doi-asserted-by":"publisher","DOI":"10.1007\/s00436-003-0828-3"},{"key":"S0031182007003952_ref009","doi-asserted-by":"publisher","DOI":"10.1136\/vr.116.21.561"},{"key":"S0031182007003952_ref036","first-page":"243","volume-title":"Proceedings of the 18th International Pig Veterinary Society Congress","author":"Torres","year":"2004"},{"key":"S0031182007003952_ref025","doi-asserted-by":"publisher","DOI":"10.1136\/vr.122.13.310"},{"key":"S0031182007003952_ref020","doi-asserted-by":"publisher","DOI":"10.1016\/S0304-4017(99)00027-8"},{"key":"S0031182007003952_ref002","doi-asserted-by":"crossref","first-page":"165","DOI":"10.1186\/BF03548344","article-title":"Shedding of oocysts in piglets experimentally infected with Isospora suis","volume":"35","author":"Christensen","year":"1994","journal-title":"Acta Veterinaria Scandinavica"},{"key":"S0031182007003952_ref006","doi-asserted-by":"publisher","DOI":"10.1080\/01652176.1994.9694449"},{"key":"S0031182007003952_ref007","first-page":"1275","article-title":"Coccidia of feral swine from Florida","volume":"181","author":"Greiner","year":"1982","journal-title":"Journal of the American Veterinary Medical Association"},{"key":"S0031182007003952_ref013","first-page":"698","article-title":"Enteric coccidial infections and coccidiosis in swine","volume":"14","author":"Lindsay","year":"1992","journal-title":"Compendium on Continuing Education for the Practicing Veterinarian"},{"key":"S0031182007003952_ref008","doi-asserted-by":"publisher","DOI":"10.1016\/0304-4017(84)90062-1"},{"key":"S0031182007003952_ref010","first-page":"117","volume-title":"NKJ projekt 59, Parasit\u00e6re infektioner hos svin","author":"Henriksen","year":"1991"},{"key":"S0031182007003952_ref10a","doi-asserted-by":"publisher","DOI":"10.1136\/vr.131.19.443"},{"key":"S0031182007003952_ref011","doi-asserted-by":"publisher","DOI":"10.1016\/S0304-4017(99)00009-6"},{"key":"S0031182007003952_ref012","unstructured":"Langkj\u00e6r M.
