Limited awareness of this keratitis etiology among ophthalmic professionals reduces the likelihood of accurate diagnosis and timely treatment. This report aims to improve the understanding of these rare infections in eye care. We present two cases of keratitis: one caused by <i>M. phaseolina</i> and another by <i>C. fructicola</i>, both of whom experienced a complicated treatment course. Traditional fungal exams yielded negative results, which limited disease identification and focused therapy. To determine the cause, we used metagenomic next-generation sequencing (mNGS) on clinical samples obtained from corneal scrapings. The mNGS report was received during therapy and quickly identified the pathogen. Based on this, we looked for treatment regimens for this kind of infection in previous literature, altered and implemented appropriate antifungal drug therapy, and the patient's condition improved. We review the literature from 1970 to 2025 on <i>M. phaseolina</i> and <i>Colletotrichum</i> spp. keratitis. We identified 10 cases of <i>M. phaseolina</i> keratitis from four studies and 72 cases of <i>Colletotrichum</i> spp. keratitis, including five of <i>C. fructicola</i>, in 43 articles. Misdiagnosis was common due to limited clinical and microbiologic suspicion. The rise of infections by rare pathogens highlights diagnostic challenges.

RGB induced the broadest responses, while blue, green, and red produced distinct wavelength-specific regulatory patterns. KEGG pathway analysis showed wavelength-dependent proteomic shifts in <i>H. erinaceus</i>, with RGB inducing the strongest metabolic and signaling responses, while blue, green, and red differentially activated energy, biosynthesis, and regulatory pathways. These results support the molecular-mechanistic approach employed and offer valuable insights into protein expression dynamics and regulatory pathways, while also clarifying how different light qualities influence the developmental processes of <i>H. erinaceus</i>.</p>","PeriodicalId":73084,"journal":{"name":"Frontiers in fungal biology","volume":"7 ","pages":"1791721"},"PeriodicalIF":4.3,"publicationDate":"2026-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13006603/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147517104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
