Possible limitations to the use of these methods were also examined. Faecal egg counts were found to accurately estimate <jats:italic>T. tenuis<\/jats:italic> worm intensities, at least up to an observed maximum of <jats:italic>c<\/jats:italic>. 8000 worms. Two egg counting methods (smear and McMaster) gave consistent results, although the exact relationship with worm intensity differed according to the method used. Faecal egg counts significantly decreased with increasing length of sample storage time, but egg counts were reliable for estimating worm intensity for three weeks. The concentration of eggs in the caecum was also found to reliably estimate worm intensity. However, egg counts from frozen gut samples cannot be used to estimate worm intensities. These results conclude that, despite some limitations, faecal and caecum egg counts provide useful and reliable ways of measuring <jats:italic>T. tenuis<\/jats:italic> intensities in red grouse.<\/jats:p>","DOI":"10.1079\/joh2003220","type":"journal-article","created":{"date-parts":[[2004,2,28]],"date-time":"2004-02-28T01:33:07Z","timestamp":1077931987000},"page":"69-76","source":"Crossref","is-referenced-by-count":89,"title":["Faecal egg counts provide a reliable measure of <i>Trichostrongylus tenuis<\/i> intensities in free-living red grouse <i>Lagopus lagopus scoticus<\/i>"],"prefix":"10.1017","volume":"78","author":[{"given":"L.J.","family":"Seivwright","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.M.","family":"Redpath","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.","family":"Mougeot","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L.","family":"Watt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.J.","family":"Hudson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2024,4,12]]},"reference":[{"key":"S0022149X00702793_ref024","doi-asserted-by":"publisher","DOI":"10.2307\/3796715"},{"key":"S0022149X00702793_ref011","doi-asserted-by":"publisher","DOI":"10.1016\/S0034-5288(18)33832-3"},{"key":"S0022149X00702793_ref022","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182001007818"},{"key":"S0022149X00702793_ref013","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000074667"},{"key":"S0022149X00702793_ref005","doi-asserted-by":"publisher","DOI":"10.1016\/0020-7519(82)90048-0"},{"key":"S0022149X00702793_ref020","doi-asserted-by":"publisher","DOI":"10.1126\/science.282.5397.2256"},{"key":"S0022149X00702793_ref027","doi-asserted-by":"publisher","DOI":"10.2307\/3934"},{"key":"S0022149X00702793_ref014","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000079452"},{"key":"S0022149X00702793_ref042","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000062594"},{"key":"S0022149X00702793_ref021","doi-asserted-by":"publisher","DOI":"10.2307\/5338"},{"key":"S0022149X00702793_ref018","volume-title":"A handbook of grouse and moorland management","author":"Hudson","year":"1995"},{"key":"S0022149X00702793_ref025","volume-title":"SAS system for mixed models","author":"Littell","year":"1996"},{"key":"S0022149X00702793_ref030","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000031127"},{"key":"S0022149X00702793_ref033","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000067317"},{"key":"S0022149X00702793_ref034","doi-asserted-by":"publisher","DOI":"10.1016\/0304-4017(81)90044-3"},{"key":"S0022149X00702793_ref041","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000051763"},{"key":"S0022149X00702793_ref008","doi-asserted-by":"publisher","DOI":"10.1016\/S0034-5288(18)31795-8"},{"key":"S0022149X00702793_ref043","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000057814"},{"key":"S0022149X00702793_ref035","volume-title":"SAS\/STAT users\u2019 guide, version 8.01.","year":"2001"},{"key":"S0022149X00702793_ref039","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000058716"},{"key":"S0022149X00702793_ref007","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000055220"},{"key":"S0022149X00702793_ref045","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000066774"},{"key":"S0022149X00702793_ref002","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000047739"},{"key":"S0022149X00702793_ref015","doi-asserted-by":"publisher","DOI":"10.2307\/4694"},{"key":"S0022149X00702793_ref019","first-page":"77","volume-title":"Ecology and genetics of host parasite infections","author":"Hudson","year":"1985"},{"key":"S0022149X00702793_ref028","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000061540"},{"key":"S0022149X00702793_ref009","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000062600"},{"key":"S0022149X00702793_ref012","first-page":"50","article-title":"A new technique for counting nematode eggs in sheep faeces","volume":"12","author":"Gordon","year":"1939","journal-title":"Journal of the Council for Scientific and Industrial Research (Australia)"},{"key":"S0022149X00702793_ref044","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182098003886"},{"key":"S0022149X00702793_ref003","doi-asserted-by":"publisher","DOI":"10.1016\/0035-9203(85)90128-2"},{"key":"S0022149X00702793_ref023","doi-asserted-by":"publisher","DOI":"10.1016\/0020-7519(71)90010-5"},{"key":"S0022149X00702793_ref031","doi-asserted-by":"publisher","DOI":"10.1079\/BJN19720093"},{"key":"S0022149X00702793_ref037","unstructured":"Shaw, J.L.
