For this, 21 H. unitaeniatus and 21 C. bimaculatum were caught in a natural environment and transported to a laboratory. After these had been euthanized, endoparasites were collected and identified. Liver alterations were evaluated histological analysis based on the severity of each lesion: stage I, organ functioning not compromised; stage II, more severe lesions that impair normal functioning of the organs; and stage III, very severe and irreversible lesions. Among the fish evaluated, 71.43% H. unitaeniatus and 61.90% C. bimaculatum were parasitized. Contracaecum sp. was found in both species; while acanthocephalans, only in H. unitaeniatus. The alterations were vacuolization, nucleus in the cell periphery, deformation of the cell outline, melanomacrophage center, hyperemia, cytoplasmic degeneration and nuclear vacuolization. Through calculating a histological alteration index, it was found that 26.19% of the specimens presented lesions in stage I; 38.09% lesions in stage II and 9.52% lesions in stage III. It was concluded that there is high prevalence of Contracaecum sp. and that the liver lesions may be adaptive responses by the fish to endoparasitic infection.<\/jats:p>","DOI":"10.1590\/s1984-29612022022","type":"journal-article","created":{"date-parts":[[2022,4,20]],"date-time":"2022-04-20T12:28:16Z","timestamp":1650457696000},"source":"Crossref","is-referenced-by-count":0,"title":["Endoparasite diversity and liver alterations in Hoplerythrinus unitaeniatus and Cichlasoma bimaculatum in a quilombola area in Maranh\u00e3o, Brazil"],"prefix":"10.1590","volume":"31","author":[{"given":"Ladilson Rodrigues","family":"Silva","sequence":"first","affiliation":[{"name":"Universidade Estadual do Maranh\u00e3o,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vitorya Mendes da Silva","family":"Monteiro","sequence":"additional","affiliation":[{"name":"Universidade Estadual do Maranh\u00e3o,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Izabela Alves","family":"Paiva","sequence":"additional","affiliation":[{"name":"Universidade Estadual do Maranh\u00e3o,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juliany Silva","family":"Mendes","sequence":"additional","affiliation":[{"name":"Universidade Estadual do Maranh\u00e3o,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Greiciene dos Santos de","family":"Jesus","sequence":"additional","affiliation":[{"name":"Universidade Estadual do Maranh\u00e3o,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcelo Victor Rodrigues da","family":"Silva","sequence":"additional","affiliation":[{"name":"Universidade Estadual do Maranh\u00e3o,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danilo Cutrim","family":"Bezerra","sequence":"additional","affiliation":[{"name":"Universidade Estadual do Maranh\u00e3o,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos Riedel Porto","family":"Carreiro","sequence":"additional","affiliation":[{"name":"Universidade Estadual do Maranh\u00e3o,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Larissa Sarmento dos Santos","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"Universidade Estadual do Maranh\u00e3o,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Viviane Correa Silva","family":"Coimbra","sequence":"additional","affiliation":[{"name":"Universidade Estadual do Maranh\u00e3o,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3970-7524","authenticated-orcid":false,"given":"Nancyleni Pinto Chaves","family":"Bezerra","sequence":"additional","affiliation":[{"name":"Universidade Estadual do Maranh\u00e3o,  Brasil;
