It is also the infection phase for the intermediate host. Under normal conditions, the larva inside the egg can survive for months in the environment; however, information regarding this phase of life of the parasite is scarce. In addition, there is no quantitative information about the structural composition of the parasite's body from a histological point of view. Such information is essential in order to support decisions aimed at controlling infestations by these parasites in fish farming. This study aimed to present a detailed description of the stages of embryonic development of <jats:italic>N. buttnerae<\/jats:italic> eggs, as well as a stereological evaluation of the body of adult females of the parasite. Three phases of development characterized the eggs: cell division (with four stages), formation of the internal nuclear mass (with four stages) and formation of the acanthor larva (with five stages). The ovary comprised 26.61% of the volume of the animal and most of it contained eggs (21.28%), ovarian balls (3.88%) and empty spaces (1.45%). These results are of great importance and will support future studies that seek to interrupt the life cycle of this parasite.<\/jats:p>","DOI":"10.1017\/s0031182021001712","type":"journal-article","created":{"date-parts":[[2021,11,2]],"date-time":"2021-11-02T08:51:55Z","timestamp":1635843115000},"page":"181-192","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":0,"title":["Embryonic development of eggs and stereological analysis of body of <i>Neoechinorhynchus buttnerae<\/i> (Golvan, 1956) (Eoacanthocephala: Neoechinorhynchidae)"],"prefix":"10.1017","volume":"149","author":[{"given":"Mayra da Silva","family":"Gon\u00e7alves","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oscar Tadeu Ferreira","family":"da Costa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Germ\u00e1n Augusto Murrieta","family":"Morey","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lucas Castanhola","family":"Dias","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edsandra Campos","family":"Chagas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1454-5197","authenticated-orcid":false,"given":"Sanny Maria de Andrade","family":"Porto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2021,11,2]]},"reference":[{"key":"S0031182021001712_ref6","first-page":"e008320","article-title":"Occurrence, pathogenicity, and control of acanthocephalosis caused by Neoechinorhynchus buttnerae: a review","volume":"29","author":"Castro","year":"2020","journal-title":"Brazilian Journal of Veterinary Parasitology"},{"key":"S0031182021001712_ref30","first-page":"221","article-title":"New aspects of acanthocephalan lacunar system as revealed in anatomical modeling by corrosion cast method","volume":"52","author":"Miller","year":"1985","journal-title":"Journal of the Helminthological Society of Washington"},{"key":"S0031182021001712_ref3","doi-asserted-by":"publisher","DOI":"10.1007\/BF00380396"},{"key":"S0031182021001712_ref9","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000045583"},{"key":"S0031182021001712_ref12","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000051337"},{"key":"S0031182021001712_ref39","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182099005272"},{"key":"S0031182021001712_ref19","doi-asserted-by":"publisher","DOI":"10.1111\/j.1699-0463.1988.tb05320.x"},{"key":"S0031182021001712_ref35","doi-asserted-by":"publisher","DOI":"10.1016\/S0065-308X(08)60266-3"},{"key":"S0031182021001712_ref14","doi-asserted-by":"crossref","first-page":"21","DOI":"10.1177\/019262338100900105","article-title":"Quantitative stereology: toxicologic pathology applications","volume":"9","author":"Felix","year":"1981","journal-title":"Toxicologic Pathology"},{"key":"S0031182021001712_ref33","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-7998.1963.tb01626.x"},{"key":"S0031182021001712_ref36","doi-asserted-by":"publisher","DOI":"10.1017\/S0031182000047879"},{"key":"S0031182021001712_ref41","unstructured":"Serra, BNV (2019) \u00d3leos essenciais de Lippia spp. no controle do est\u00e1gio inicial do acantoc\u00e9falo Neoechinorhynchus buttnerae, endohelminto de tambaqui Colossoma macropomum.
