Quantitative studies on 55 horses showed the adult cyathostome burdens to rise to a sharp peak (average over 400,000\/horse) in April-June and a lower one in November-December. Parallel fluctuations occurred in the lumen populations of 4thstage larvae. The most numerous cyathostomes were generally those species with the highest prevalence. The five most plentiful (<jats:italic>C. nassatus, Cyathostomum catinatum, Cylicostephanus longibursatus, C. minutus and C. goldi<\/jats:italic>) comprised over 90% of the total number of adult cyathostomes recovered. The three regions of the large intestine had adult cyathostome faunas of different composition. That of the dorsal colon was dominated by <jats:italic>C. longibursatus<\/jats:italic> and <jats:italic>C. goldi<\/jats:italic>, the ventral colon by <jats:italic>Cylicocyxlus nassatus<\/jats:italic> and <jats:italic>Cyathostomum catinatum<\/jats:italic>, while the sparsely inhabited caecum accommodated several equally numerous species. Each species showed a characteristic site distribution, 11 occurring predominantly in the ventral colon, eight in the dorsal colon and two in the caecum. Seasonal changes in the site distributions of <jats:italic>C. catinatum<\/jats:italic> and <jats:italic>Cylicocyclus nassatus<\/jats:italic> and in the size of the cyathostome burdens are discussed in relation to the epidemiology of cyathostome infections.<\/jats:p>","DOI":"10.1017\/s0022149x00027760","type":"journal-article","created":{"date-parts":[[2009,6,5]],"date-time":"2009-06-05T11:40:03Z","timestamp":1244202003000},"page":"203-214","source":"Crossref","is-referenced-by-count":123,"title":["The prevalence, relative abundance and site distribution of nematodes of the subfamily Cyathostominae in horses killed in Britain"],"prefix":"10.1017","volume":"50","author":[{"given":"Colin P.","family":"Ogbourne","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2009,6,5]]},"reference":[{"key":"S0022149X00027760_ref032","first-page":"36","article-title":"Quantitative studies on the nematode parasites of horses and mules","volume":"34","author":"Ward","year":"1948","journal-title":"Journal of Parasitology"},{"key":"S0022149X00027760_ref026","first-page":"779","article-title":"Intestinal parasites of Shetland ponies in the north of Scotland","volume":"51","author":"Robertson","year":"1939","journal-title":"Veterinary Record"},{"key":"S0022149X00027760_ref022","unstructured":"Mathieson A.
