First, a comparison between individual counts and composite counts was conducted using sheep on two farms with different levels of infection. Faecal samples were collected from 50 sheep on each farm at the time of TCBZ treatment and 21\u00a0days later. The results showed that a composite fluke egg count (CFEC) was as sensitive as using individual samples, and the test was subsequently validated on an additional 18 sheep farms. The pre\u2010 and post\u2010treatment CFECs using five composite samples were subjected to bootstrap analysis. The variance in fluke egg counts of composite samples was high, but analyses indicated that 20\u00a0individual samples analysed as two composites was as sensitive as using five composites. The two\u2010composite assay was evaluated on another five farms. On seven out of 25 farms sampled, egg counts either did not decrease significantly or increased following treatment, suggesting TCBZ resistance on these farms. This assay represents a practical field test that can be used in the first instance to evaluate the efficacy of TCBZ on sheep farms where resistance is suspected.<\/jats:p>","DOI":"10.1136\/vr.100588","type":"journal-article","created":{"date-parts":[[2012,7,12]],"date-time":"2012-07-12T00:13:45Z","timestamp":1342052025000},"page":"153-153","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":45,"title":["Composite faecal egg count reduction test to detect resistance to triclabendazole in\n                    <i>Fasciola hepatica<\/i>"],"prefix":"10.1002","volume":"171","author":[{"given":"R.","family":"Daniel","sequence":"first","affiliation":[{"name":"Animal Health and Veterinary Laboratories Agency (AHVLA) Carmarthen Job's Well Road, Johnstown Carmarthen SA31 3EZ UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"van Dijk","sequence":"additional","affiliation":[{"name":"Department of Epidemiology and Population Health Institute of Infection and Global Health, Leahurst Chester High Road Neston Cheshire CH64 7TE UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Jenkins","sequence":"additional","affiliation":[{"name":"Department of Parasitology Faculty of Veterinary Medicine University of Kafkas Kars 36040 Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Akca","sequence":"additional","affiliation":[{"name":"Animal Health and Veterinary Laboratories Agency (AHVLA) Penrith Investigation Centre and Laboratory Calthwaite Penrith Cumbria CA11 9RR UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.","family":"Mearns","sequence":"additional","affiliation":[{"name":"Veterinary Parasitology Institute of Infection and Global Health University of Liverpool Pembroke Place Liverpool L69 7ZJ UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.
