Metacercariae that succeeded in developing into adult worms, showed low fecundity levels. Furthermore, 30% of eggs laid showed abnormal shape; however, all normal and abnormal eggs failed to hatch into miracidia. The effectiveness of UV-irradiated metacercariae as a vaccine was investigated. Compared to control unvaccinated herons, the vaccinated group showed a significantly high protection rate (73.8%) against challenge.<jats:italic>In vitro<\/jats:italic>, worm development after challenge showed decreased fecundity and increased egg abnormalities, where only 1.5% of all eggs produced hatched into miracidia. A passive haemagglutination test revealed increased antibody titres against soluble adult worm antigen in both vaccinated and vaccinated-challenged birds. It was concluded that vaccination of herons using encysted metacercariae UV-irradiated for 60\u00a0min can protect them against challenge infection.<\/jats:p>","DOI":"10.1017\/s0022149x09374313","type":"journal-article","created":{"date-parts":[[2009,5,13]],"date-time":"2009-05-13T09:09:20Z","timestamp":1242205760000},"page":"361-367","source":"Crossref","is-referenced-by-count":3,"title":["The protective capacity of UV-exposed<i>Clinostomum complanatum<\/i>metacercariae against challenge infections in<i>Ardeola ibis ibis<\/i>"],"prefix":"10.1017","volume":"83","author":[{"given":"G.","family":"Allam","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.M.","family":"Aboel Hadid","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2009,5,13]]},"reference":[{"key":"S0022149X09374313_ref4","first-page":"81","volume-title":"Protocolos para laborat\u00f3rio-coletae processamento de parasitas do pescado","author":"Amato","year":"1991"},{"key":"S0022149X09374313_ref29","first-page":"55","article-title":"DNA repair deficient photodermatoses","volume":"9","author":"Lehmann","year":"1990","journal-title":"Seminars in Dermatology"},{"key":"S0022149X09374313_ref2","first-page":"135","article-title":"Some studies helminth parasites of buff backed heron (Ardeola ibis ibis) with special reference to its role in transmission of Clinostomum complanatum in Beni-Suef Governorate","volume":"5","author":"Aboel Hadid","year":"2007","journal-title":"Beni-Suef Veterinary Medicine Journal"},{"key":"S0022149X09374313_ref50","first-page":"300","article-title":"Migration kinetics of ultraviolet-attenuated Schistosoma mansoni in ICR mice","volume":"41","author":"Kumagai","year":"1992","journal-title":"Japanese Journal of Parasitology"},{"key":"S0022149X09374313_ref11","doi-asserted-by":"publisher","DOI":"10.1016\/S0065-308X(08)60048-2"},{"key":"S0022149X09374313_ref5","doi-asserted-by":"publisher","DOI":"10.7589\/0090-3558-28.3.470"},{"key":"S0022149X09374313_ref24","first-page":"885","article-title":"Protective immunity elicited by ultraviolet-irradiated third-stage infective hookworm (Necator americanus and Ancylostoma caninum) larvae in mice and hamsters","volume":"37","author":"Jian","year":"2006","journal-title":"Southeast Asian Journal of Tropical Medicine and Public Health"},{"key":"S0022149X09374313_ref13","doi-asserted-by":"publisher","DOI":"10.1016\/0014-4894(83)90002-4"},{"key":"S0022149X09374313_ref42","doi-asserted-by":"publisher","DOI":"10.11150\/kansenshogakuzasshi1970.72.1242"},{"key":"S0022149X09374313_ref19","doi-asserted-by":"publisher","DOI":"10.1016\/0006-3002(52)90004-8"},{"key":"S0022149X09374313_ref28","doi-asserted-by":"crossref","first-page":"593","DOI":"10.1007\/s004360100391","article-title":"Inhibitory effect of different UV lamps on the infectivity of taeniid eggs","volume":"87","author":"Lagapa","year":"2001","journal-title":"Parasitology Research"},{"key":"S0022149X09374313_ref16","doi-asserted-by":"publisher","DOI":"10.1088\/0031-9155\/36\/3\/001"},{"key":"S0022149X09374313_ref48","doi-asserted-by":"publisher","DOI":"10.1017\/S0022149X0000835X"},{"key":"S0022149X09374313_ref21","volume-title":"Biological effects of ultraviolet radiation","author":"Harm","year":"1980"},{"key":"S0022149X09374313_ref32","first-page":"33","article-title":"Biochemical studies on the genetic material of fresh water snails intermediate hosts of schistosomiasis.
