It is caused by Paracoccidioides ceti, an uncultivable fungal species recently classified within the Paracoccidioides genus. Although several molecular markers have been used to investigate the PCMC pathogen, the alpha-tubulin gene (TUB1), commonly utilized in genetic studies of cultivable Paracoccidioides, has remained unexplored in this taxon. In this study, we applied a nested polymerase chain reaction targeting TUB1 to amplify fungal sequences from two new cases of PCMC in Brazil: a Lahille\u2019s bottlenose dolphin (Tursiops truncatus gephyreus) and a common bottlenose dolphin (T. truncatus truncatus). Comparative analysis revealed that the sequences obtained from the infected dolphins were identical to each other and shared similarities with fungi belonging to the P. brasiliensis complex. In the haplotype analysis, P. ceti was found to be only a few mutational steps away from P. brasiliensis sensu stricto and P. americana. Notably, the latter shared the same cleavage sites as P. ceti in the in silico restriction fragment length polymorphism analysis. Our findings demonstrate that the nested PCR assay, originally developed for cultivable Paracoccidioides species, is also effective in amplifying TUB1 from P. ceti. Therefore, this method can be considered an additional tool for phylogenetic studies of this uncultivable species, contributing to a better understanding of this peculiar pathogen.<\/jats:p>","DOI":"10.1093\/mmy\/myaf084","type":"journal-article","created":{"date-parts":[[2025,9,19]],"date-time":"2025-09-19T20:08:28Z","timestamp":1758312508000},"source":"Crossref","is-referenced-by-count":0,"title":["Partial alpha-tubulin gene amplification by nested PCR as a tool for <i>Paracoccidioides ceti<\/i> identification"],"prefix":"10.1093","volume":"63","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7160-319X","authenticated-orcid":false,"given":"Igor Massahiro de Souza","family":"Suguiura","sequence":"first","affiliation":[{"name":"State University of Londrina Laboratory of Animal Immunology, Department of Immunology, Parasitology and General Pathology, , PR 445 Km 380, 86055-900, Londrina ,","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9013-6443","authenticated-orcid":false,"given":"Victor Hugo Brunaldi","family":"Marutani","sequence":"additional","affiliation":[{"name":"State University of Londrina Department of Preventive Veterinary Medicine, , PR 445 Km 380, 86055-900, Londrina, Paran\u00e1 ,","place":["Brazil"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9939-7807","authenticated-orcid":false,"given":"Pedro","family":"Volkmer\u00a0de\u00a0Castilho","sequence":"additional","affiliation":[{"name":"Marine Animal Stabilization Unit, Zoology Laboratory , UDESC\/Laguna, Av.
