The main lesions observed were lymphoplasmacytic and focally necrotizing encephalitis, necrotizing to granulomatous adrenalitis, myocarditis, and inflammation in the intestinal wall, associated with protozoal tissue cysts and tachyzoites. Additionally, the individual had a 5.6 mm (crown-rump length) early-stage embryo in the left uterine horn, which had multifocal necrotizing lesions with intralesional tissue cysts and tachyzoites in the parenchyma. Immunohistochemistry and PCR and sequencing of the internal transcribed spacer 1 region confirmed a Toxoplasma gondii infection. Further genotyping revealed an atypical type II genotype with a type I pattern for the Apico locus. Narrow-ridged finless porpoises are an endangered coastal species already facing various anthropogenic threats. Toxoplasmosis, especially with its ability to transmit to an early-stage embryo, should be considered an emerging threat to this vulnerable species.<\/jats:p>","DOI":"10.7589\/jwd-d-20-00041","type":"journal-article","created":{"date-parts":[[2020,10,6]],"date-time":"2020-10-06T13:43:52Z","timestamp":1601991832000},"page":"205-210","source":"Crossref","is-referenced-by-count":3,"title":["Disseminated Toxoplasmosis in a Narrow-Ridged Finless Porpoise (Neophocaena asiaeorientalis) with Transplacental Embryonal Transmission"],"prefix":"10.7589","volume":"57","author":[{"given":"Shotaro","family":"Nakagun","sequence":"first","affiliation":[{"name":"Laboratory of Veterinary Pathology, Obihiro University of Agriculture and Veterinary Medicine, Inada, Obihiro, Hokkaido 080-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masao","family":"Amano","sequence":"additional","affiliation":[{"name":"Graduate School of Fisheries and Environmental Sciences, Nagasaki University, Bunkyo, Nagasaki, Nagasaki 852-8521, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"El-Sayed N.","family":"El-Alfy","sequence":"additional","affiliation":[{"name":"National Research Center for Protozoan Diseases, Obihiro University of Agriculture and Veterinary Medicine, Inada, Obihiro, Hokkaido 080-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshifumi","family":"Nishikawa","sequence":"additional","affiliation":[{"name":"National Research Center for Protozoan Diseases, Obihiro University of Agriculture and Veterinary Medicine, Inada, Obihiro, Hokkaido 080-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akira","family":"Shiozaki","sequence":"additional","affiliation":[{"name":"Graduate School of Fisheries and Environmental Sciences, Nagasaki University, Bunkyo, Nagasaki, Nagasaki 852-8521, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuko","family":"Tajima","sequence":"additional","affiliation":[{"name":"National Museum of Nature and Science, Amakubo, Tsukuba, Ibaraki 305-0005, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tadasu K.","family":"Yamada","sequence":"additional","affiliation":[{"name":"National Museum of Nature and Science, Amakubo, Tsukuba, Ibaraki 305-0005, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshiyasu","family":"Kobayashi","sequence":"additional","affiliation":[{"name":"Laboratory of Veterinary Pathology, Obihiro University of Agriculture and Veterinary Medicine, Inada, Obihiro, Hokkaido 080-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"4415","reference":[{"key":"2","doi-asserted-by":"crossref","unstructured":"PA Conrad, MA Miller, C Kreuder, et al.  \"Int J Parasitol.\"  35, \"Transmission of Toxoplasma: Clues from the study of sea otters as sentinels of Toxoplasma gondii flow into the marine environment.\" 1155 (2005)","DOI":"10.1016\/j.ijpara.2005.07.002"},{"key":"1","doi-asserted-by":"crossref","unstructured":"M.
