This could be attributed in part to a point mutation in the squalene epoxidase (<em>SQLE</em>) gene. In this study, point mutations in the <em>SQLE</em> gene were studied in <em>T. rubrum</em> and <em>T. mentagrophytes/T. interdigitale</em> species complex as two main causative agents of dermatophytosis. Antifungal susceptibility of clinical isolates of <em>T. rubrum</em> (<em>n</em> = 27) and <em>T. mentagrophytes/T. interdigitale</em> (<em>n</em> = 56) was assessed using the M38–3rd edition CLSI method. The <em>SQLE</em> gene and <em>ITS</em> region were sequenced for all the fungal strains, and the mutation sites and genotypes of the terbinafine-resistant strains were characterized. The results demonstrated that, in <em>T. rubrum</em>, the minimum inhibitory concentration of terbinafine (MIC<sub>50</sub> and MIC<sub>90</sub>) was 0.03 μg/ml, and the geometric mean (G mean) concentration was 0.02. For the <em>T. mentagrophytes</em> complex, the MIC<sub>50</sub> and MIC<sub>90</sub> were 0.03 and 1.0 μg/ml, respectively, and the G mean concentration was 0.04 μg/ml.

Due to its broad spectrum and safety profile when compared to other antifungals, itraconazole (ITZ) has been widely used in the treatment and prophylaxis of fungal infections, both in human and veterinary medicine. The dose and duration of management depend on factors such as the type of fungal pathogen, the site of infection, sensitivity to ITZ, chronic stages of the disease, the health status of the hosts, pharmacological interactions with other medications and the therapeutic protocol used. In veterinary practice, ITZ doses generally vary between 3 mg/kg and 50 mg/kg, once or twice a day. In humans, doses usually vary between 100 and 400 mg/day. As human and veterinary fungal infections are increasingly associated, and ITZ is one of the main medications used, this review addresses relevant aspects related to the use of this drug in both clinics, including case reports and different clinical aspects available in the literature.</p></div>","PeriodicalId":14824,"journal":{"name":"Journal de mycologie medicale","volume":"34 2","pages":"Article 101473"},"PeriodicalIF":3.6,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140124978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
