Examination of data from equine cysts revealed that the majority of FAAs were present in significantly greater concentrations in secondary cysts, glycine being over 30 times more concentrated. Values for total carbohydrates and glucose did not, however, differ significantly and total protein content was greater in primary cysts. Comparison of the (FAA) pool of secondary equine and ovine cysts revealed strain variation. It was demonstrated that most FAAs were more concentrated in hydatid fluid than in the corresponding host plasma, many concentration ratios exceeding 10. The possible contribution that mediated amino acid transport across the cyst wall and parasite amino acid metabolism makes to the composition of the FAA pool was discussed. No significant plasma aminoacidaemia was associated with infection.<\/jats:p>","DOI":"10.1017\/s0031182000059771","type":"journal-article","created":{"date-parts":[[2009,6,5]],"date-time":"2009-06-05T16:04:53Z","timestamp":1244217893000},"page":"135-143","source":"Crossref","is-referenced-by-count":10,"title":["<i>Echinococcus granulosus<\/i>: a comparison of free amino acid concentration in hydatid fluid from primary and secondary cysts and host plasma"],"prefix":"10.1017","volume":"98","author":[{"given":"Hilary","family":"Hurd","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2009,4,6]]},"reference":[{"key":"S0031182000059771_ref006","first-page":"4","article-title":"Studies on amino acids and sugars in larval Hydatigena taeniaeformis (Batch, 1758)","volume":"2","author":"Gaur","year":"1981","journal-title":"Proceedings of the Indian Academy of Parasitology"},{"key":"S0031182000059771_ref017","first-page":"347","article-title":"Estudio de algunas propiedades fisicas y componentes quimicos del liquido y pared germinativa de quistes hidatidicos de diversas especies y de diferente localizacion","volume":"31","author":"Sanchez","year":"1971","journal-title":"Revta Iberica Parasitologia"},{"key":"S0031182000059771_ref016","first-page":"335","article-title":"The determination of sugar in blood and spinal fluid with anthrone reagent","volume":"212","author":"Roe","year":"1955","journal-title":"Journal of Biochemistry"},{"key":"S0031182000059771_ref012","first-page":"114","volume-title":"The Biology of Echinococcus and Hydatid Disease","author":"Mcmanus","year":"1986"},{"key":"S0031182000059771_ref001","doi-asserted-by":"publisher","DOI":"10.1016\/0020-7519(78)90058-9"},{"key":"S0031182000059771_ref002","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000046527"},{"key":"S0031182000059771_ref010","first-page":"314","article-title":"Metabolism of amino acids in some parasites II.
