Diagnosis of the parasite infection by stool examination for the presence of eggs was less sensitive than the worm recovery technique. Using Stoll's dilution and formalin\u2013ether technique, no eggs were detected in the faeces of 20 cases harbouring low worm burdens (&lt; 20 worms). The quantitative faecal egg count by Stoll's dilution technique showed a strikingly close positive correlation with the number of worms recovered (<jats:italic>r<\/jats:italic> = 0\u00b796, <jats:italic>P<\/jats:italic> &lt; 0\u00b7001) indicating a strong linear association between eggs per gram of faeces (epg) and worm burden. The number of epg per worm was inversely correlated to the worm burden (<jats:italic>P<\/jats:italic> &lt; 0\u00b7001), suggesting that density-dependent constraints on fecundity could operate to restrict egg output in heavy infections. The accuracy of egg counts for estimating worm burden and its relevance to parasite epidemiological research are discussed.<\/jats:p>","DOI":"10.1017\/s0031182000062594","type":"journal-article","created":{"date-parts":[[2009,6,5]],"date-time":"2009-06-05T10:33:51Z","timestamp":1244198031000},"page":"277-281","source":"Crossref","is-referenced-by-count":101,"title":["Relationship between faecal egg count and worm burden of <i>Opisthorchis viverrini<\/i> in human autopsy cases"],"prefix":"10.1017","volume":"102","author":[{"given":"P.","family":"Sithithaworn","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Tesana","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"V.","family":"Pipitgool","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Kaewkes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.","family":"Pairojkul","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.","family":"Sripa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Paupairoj","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Thaiklar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2009,4,6]]},"reference":[{"key":"S0031182000062594_ref019","doi-asserted-by":"publisher","DOI":"10.1016\/0020-7519(88)90099-9"},{"key":"S0031182000062594_ref009","first-page":"60","article-title":"Opisthorchiasis: a clinicopathologic study of 154 autopsy cases","volume":"9","author":"Koompirochana","year":"1978","journal-title":"Southeast Asian Journal of Tropical Medicine and Public Health"},{"key":"S0031182000062594_ref006","doi-asserted-by":"publisher","DOI":"10.4269\/ajtmh.1971.20.667"},{"key":"S0031182000062594_ref008","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000080197"},{"key":"S0031182000062594_ref007","doi-asserted-by":"publisher","DOI":"10.1016\/0035-9203(83)90132-3"},{"key":"S0031182000062594_ref002","doi-asserted-by":"publisher","DOI":"10.4269\/ajtmh.1977.26.702"},{"key":"S0031182000062594_ref015","first-page":"81","article-title":"Studies on Opisthorchis viverrini in Thailand","volume":"62","author":"Sadun","year":"1955","journal-title":"American Journal of Tropical Medicine and Hygiene"},{"key":"S0031182000062594_ref020","doi-asserted-by":"publisher","DOI":"10.4269\/ajtmh.1982.31.1156"},{"key":"S0031182000062594_ref001","doi-asserted-by":"publisher","DOI":"10.4269\/ajtmh.1968.17.38"},{"key":"S0031182000062594_ref004","doi-asserted-by":"publisher","DOI":"10.1016\/0035-9203(90)90159-C"},{"key":"S0031182000062594_ref011","first-page":"1119","article-title":"Public health aspects of opisthorchiasis in Thailand","volume":"34","author":"Preuksaraj","year":"1984","journal-title":"Drug Research"},{"key":"S0031182000062594_ref013","doi-asserted-by":"publisher","DOI":"10.1016\/0035-9203(89)90662-7"},{"key":"S0031182000062594_ref005","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000062600"},{"key":"S0031182000062594_ref003","doi-asserted-by":"publisher","DOI":"10.1016\/0035-9203(82)90272-3"},{"key":"S0031182000062594_ref010","doi-asserted-by":"publisher","DOI":"10.4269\/ajtmh.1984.33.73"},{"key":"S0031182000062594_ref012","first-page":"405","article-title":"Clinical features in severe opisthorchiasis viverrini","volume":"16","author":"Pungpak","year":"1985","journal-title":"Southeast Asian Journal of Tropical Medicine and Public Health"},{"key":"S0031182000062594_ref022","doi-asserted-by":"publisher","DOI":"10.1017\/S0022149X00009482"},{"key":"S0031182000062594_ref014","first-page":"326","article-title":"An ether sedimentation technique for routine stool examinations.","volume":"8","author":"Ritchie","year":"1948","journal-title":"Bulletin of the United States Army Medical Department"},{"key":"S0031182000062594_ref021","doi-asserted-by":"publisher","DOI":"10.1080\/00034983.1953.11685570"},{"key":"S0031182000062594_ref017","first-page":"59","article-title":"Investigations on the control of hookworm disease.
