The plasmodia show asynchronous development, at any one time composed of mature spores and all sporogonic stages. The ellipsoidal spore body, measuring 10\u00b74 \u03bcm long and 5\u00b77 \u03bcm wide, consists of 2 equal shell valves adhering together along the straight suture line. Each valve has a caudal process measuring 23\u00b73 \u03bcm in length. There are 2 symmetric polar capsules, without intercapsular appendix, measuring 5\u00b70 \u03bcm\u00d72\u00b71 \u03bcm, and each has a polar filament with 7\u20138 coils. In general, ultrastructural details of sporoblast and spore development are in agreement with previously described myxosporeans. Some ultrastructural aspects such as cellular alterations of the pericyte in the different organs infected and characterization of the sporoplasmosomes during the sporoplasm maturation are described. This parasite was studied under light and electron microscope and compared with others species of the genus <jats:italic>Henneguya<\/jats:italic>, considering also host specificity. From our observations we propose the creation of a new species, <jats:italic>Henneguya friderici<\/jats:italic> n. sp.<\/jats:p>","DOI":"10.1017\/s0031182003002944","type":"journal-article","created":{"date-parts":[[2003,5,9]],"date-time":"2003-05-09T09:29:48Z","timestamp":1052472588000},"page":"313-319","source":"Crossref","is-referenced-by-count":40,"title":["Light and electron microscopic study of the myxosporean, <i>Henneguya friderici<\/i> n. sp. from the Amazonian teleostean fish, <i>Leporinus friderici<\/i>"],"prefix":"10.1017","volume":"126","author":[{"given":"G.","family":"CASAL","sequence":"first","affiliation":[]},{"given":"E.","family":"MATOS","sequence":"additional","affiliation":[]},{"given":"C.","family":"AZEVEDO","sequence":"additional","affiliation":[]}],"member":"56","published-online":{"date-parts":[[2003,4,30]]},"container-title":["Parasitology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0031182003002944","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,4,2]],"date-time":"2019-04-02T15:18:10Z","timestamp":1554218290000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0031182003002944\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003,4]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2003,4]]}},"alternative-id":["S0031182003002944"],"URL":"https:\/\/doi.org\/10.1017\/s0031182003002944","relation":{},"ISSN":["0031-1820","1469-8161"],"issn-type":[{"value":"0031-1820","type":"print"},{"value":"1469-8161","type":"electronic"}],"subject":[],"published":{"date-parts":[[2003,4]]}}}
