Resumo: | Caretta caretta, one of the five sea turtle species in Brazil, is currently listed as globally endangered. While health assessments are crucial for monitoring population status, they are infrequent and lack systematic implementation. Evaluating the health condition of sea turtles can occur through examinations of both live and deceased animals. Carcasses play a pivotal role in identifying diseases and potential threats impacting the species. Therefore, this study presents the histopathological findings from 20 dead stranded C. caretta along the Paraná coast between 2015 and 2021. All individuals underwent measurements, and necropsies were conducted. The mean curved carapace length (cm) was 67.3 ± 6.9 (49.4 – 81.5). Body condition was classified as good in 13 animals, fair in four, poor in two, and undetermined in one. Fourteen females, four males, and two undetermined sexes were registered, with a mean age of 15.8 ± 3,89 (ranging from 9 – 24) years. Evidence of anthropogenic interaction (10 bycatch interactions, 6 marine debris, 2 oil interactions combined with marine debris) was noted in 80.0% of the animals. Histological changes primarily affected the liver, lungs, spleen, and kidneys, with prominent alterations such as inflammatory infiltrate (interstitial pneumonia, heterophilic splenitis, nephritis, endocarditis), congestion, and hepatic and renal hydropic degeneration. This study significantly contributes to our understanding of pathological findings in stranded wild C. caretta on the Paraná coast, offering valuable insights into the health of these animals and aiding in the conservation efforts to protect their populations. |

As avaliações de saúde são fundamentais para monitorar a situação dessa população, no entanto não são realizadas sistematicamente resultando em escassez de dados. O estado de saúde das tartarugas marinhas pode ser investigado por meio de animais vivos e mortos. As carcaças são essenciais para a identificação de doenças e outras ameaças potenciais que afetam as espécies. Portanto, este estudo relata os achados histopatológicos de 20 C. caretta encalhadas mortas no litoral do Paraná, entre 2015 e 2021. Todos os indivíduos foram medidos e autopsiados. O comprimento curvo médio da carapaça (cm) foi de 67,3 ± 6,9 (49,4 – 81,5); a condição corporal foi boa em 13 animais, regular em quatro, ruim em dois e indeterminada em um. Foram registrados 14 animais do sexo feminino, quatro do sexo masculino e dois de sexo indeterminado, com média de idade de 15,8 ± 3,89 (variação de 9 – 24) anos. Evidências de interação antrópica (10 interações de captura incidental, 6 detritos marinhos, 2 interações de óleo concomitante a detritos marinhos) foram registradas em 80% dos animais. As alterações histológicas acometeram principalmente fígado, pulmões, baço e rins, sendo as principais alterações infiltrados inflamatórios (pneumonia intersticial, esplenite heterofílica, nefrite, endocardite), congestão, degeneração hidrópica hepática e renal. Este estudo contribui para o conhecimento dos achados patológicos em C. caretta encalhadas no litoral do Paraná e com informações importantes sobre a saúde dos animais, sendo que os dados obtidos podem colaborar na conservação das populações.UEL2024-04-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4821910.5433/1679-0359.2024v44n2p479Semina: Ciências Agrárias; Vol. 44 No. 2 (2024); 479-494Semina: Ciências Agrárias; v. 44 n. 2 (2024); 479-4941679-03591676-546Xreponame:Semina.
