Increasing antifungal resistance and limited access to timely diagnostics hamper effective management, particularly in resource-limited settings. There is therefore an urgent need for reliable point-of-care diagnostics to guide treatment and support antifungal stewardship. Here, we report the development and validation of molecular assays based on loop-mediated isothermal amplification (LAMP) for rapid identification of dermatophytes and antifungal resistance-associated alleles. For taxonomic identification, we developed conventional LAMP assays targeting pan-dermatophytes,\n                      <jats:italic toggle=\"yes\">Microsporum<\/jats:italic>\n                      spp.,\n                      <jats:italic toggle=\"yes\">Trichophyton rubrum<\/jats:italic>\n                      complex, and\n                      <jats:italic toggle=\"yes\">Trichophyton mentagrophytes<\/jats:italic>\n                      complex. For detection of single-nucleotide polymorphisms (SNPs) associated with terbinafine resistance, we developed competitive SNP-based LAMP (sbLAMP) assays using unmodified self-stabilizing (USS) primers to differentiate specific from non-specific amplification.

Using available clinical isolates, assays demonstrated sensitive and specific detection and were compatible with a simple colorimetric readout. For resistance detection, optimized primers validated wild-type allelic status of\n                      <jats:italic toggle=\"yes\">T. rubrum<\/jats:italic>\n                      isolates, showing delayed amplification in mutant assays. Together, these assays show a means by which taxonomic identification and allele-specific resistance detection of dermatophyte infections might be possible within a point-of-care application. Such an application could support targeted treatment in remote or resource-limited settings that will also aid in the stewardship of emerging antifungal resistance.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>IMPORTANCE<\/jats:title>\n                    <jats:p>Antifungal resistance is an emerging global health threat, with the World Health Organization identifying inadequate fungal diagnostics as a major barrier to effective treatment and surveillance. Dermatophyte infections affect up to one-quarter of the global population, yet diagnosis remains slow, laboratory-dependent, and often inaccessible in the communities most affected. This diagnostic gap contributes to empirical antifungal use, delayed treatment, and the emergence of resistance to frontline therapies, such as terbinafine. Here, we present a proof-of-concept molecular diagnostic platform based on loop-mediated isothermal amplification (LAMP) for the rapid identification of dermatophyte infections and associated antifungal resistance markers. By integrating species-level detection with allele-specific resistance profiling in a rapid, low-cost, and portable format, these assays provide a foundation for future point-of-care diagnostics that could improve access to timely fungal diagnosis, enable targeted antifungal therapy, and strengthen global antifungal stewardship, particularly in resource-limited settings.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1128\/spectrum.00669-26","type":"journal-article","created":{"date-parts":[[2026,9,24]],"date-time":"2026-09-24T13:00:36Z","timestamp":1790254836000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Development of a rapid LAMP assay toward point-of-care detection of dermatophyte infections and antifungal resistance"],"prefix":"10.1128","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2319-187X","authenticated-orcid":true,"given":"Georgia","family":"Wunderlich","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03r8z3t63","id-type":"ROR","asserted-by":"publisher"}],"name":"School of Biomedical Sciences, University of New South Wales","place":["Sydney, Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shannen","family":"Butterly","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03r8z3t63","id-type":"ROR","asserted-by":"publisher"}],"name":"School of Biomedical Sciences, University of New South Wales","place":["Sydney, Australia"]},{"name":"St. Vincent's Centre for Applied Medical Research","place":["Sydney, Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Johnson","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03r8z3t63","id-type":"ROR","asserted-by":"publisher"}],"name":"School of Biomedical Sciences, University of New South Wales","place":["Sydney, Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6011-9757","authenticated-orcid":false,"given":"Artiene","family":"Tatian","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03r8z3t63","id-type":"ROR","asserted-by":"publisher"}],"name":"School of Clinical Medicine, University of New South Wales","place":["Kensington, NSW, Australia"]},{"id":[{"id":"https:\/\/ror.org\/02tj04e91","id-type":"ROR","asserted-by":"publisher"}],"name":"Department of Paediatric Dermatology, Sydney Children's Hospital Randwick","place":["Randwick, NSW, Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0275-352X","authenticated-orcid":true,"given":"Jake","family":"Baum","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03r8z3t63","id-type":"ROR","asserted-by":"publisher"}],"name":"School of Biomedical Sciences, University of New South Wales","place":["Sydney, Australia"]},{"name":"Department of Life Sciences, Imperial College London","place":["London, United Kingdom"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"235","published-online":{"date-parts":[[2026,9,24]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jdin.2020.10.003"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41564-024-01720-y"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1111\/jam.14611"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1093\/jac\/dku053"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/myc.13091"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41579-023-00960-9"},{"key":"e_1_3_4_8_2","unstructured":"World Health Organisation. 2025.
