Although transformation is possible in C. auris, no plasmids are available that can serve as cloning or shuttle vectors. C. auris centromeres have been well characterized but have not been explored further as molecular tools. We tested C. auris centromeric sequences to identify which, if any, could be used to create a plasmid that was stably maintained after transformation. We cloned all seven C. auris centromeric sequences and tested them for transformation frequency and stability. Transformation frequency varied significantly; however, one was found to transform at a very high frequency. A 1.7 Kb subclone of this sequence was used to construct a shuttle vector. The vector was stable with selection and maintained at ~1 copy per cell but could be easily lost when selection was removed, which suggested that the properties of the centromeric sequence were more Autonomously Replicating Sequence (ARS)-like than centromere-like when part of a plasmid. Rescue of this plasmid from transformed C. auris cells into E. coli revealed that it remained intact after the initial C. auris transformation, even when carrying large inserts. The plasmid was found to be able to transform all four clades of C. auris, with varying frequencies. This plasmid is an important new reagent in the C. auris molecular toolbox, which will enhance the investigation of this human fungal pathogen.<\/jats:p>","DOI":"10.3390\/jof10070477","type":"journal-article","created":{"date-parts":[[2024,7,11]],"date-time":"2024-07-11T11:33:22Z","timestamp":1720697602000},"page":"477","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Development of a Shuttle Vector That Transforms at High Frequency for the Emerging Human Fungal Pathogen: Candida auris"],"prefix":"10.3390","volume":"10","author":[{"suffix":"II","given":"Brenden","family":"Determann","sequence":"first","affiliation":[{"name":"The Department of Microbiology, Immunology, and Molecular Genetics, The University of Texas Health Science Center at San Antonio, San Antonio, TX 78229-3900, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianmin","family":"Fu","sequence":"additional","affiliation":[{"name":"The Department of Microbiology, Immunology, and Molecular Genetics, The University of Texas Health Science Center at San Antonio, San Antonio, TX 78229-3900, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5909-5815","authenticated-orcid":false,"given":"Brian L.","family":"Wickes","sequence":"additional","affiliation":[{"name":"The Department of Microbiology, Immunology, and Molecular Genetics, The University of Texas Health Science Center at San Antonio, San Antonio, TX 78229-3900, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"41","DOI":"10.1111\/j.1348-0421.2008.00083.x","article-title":"Candida auris sp. nov., a novel ascomycetous yeast isolated from the external ear canal of an inpatient in a Japanese hospital","volume":"53","author":"Satoh","year":"2009","journal-title":"Microbiol.
