ЧУВСТВИТЕЛЬНОСТЬ ВОЗБУДИТЕЛЕЙ ДЕРМАТОФИТИЙ К ПРОТИВОГРИБКОВЫМ СРЕДСТВАМ, АНТИСЕПТИКАМ И ДЕЗИНФЕКТАНТАМ

Abstract

Dermatophytes form the group of fungal pathogens of humans, which includes 43 species, of which the most important representatives are the genera Trichophyton and Microsporum. In recent years, patients with the established diagnoses of “mycosis pedis“, "skin mycosis of the palms“ and "onychomycosis”, and associations of dermatophytes and moulds as well as dermatophytes as an aetiological factor in mixed infections and yeast-like fungi often play a role. The main objective of the current study was to determine the susceptibility of dermatophytosis pathogens (Trichophyton spp., Microsporum spp.) isolated from samples of biological from patients with mycoses to modern antifungals, antiseptics and disinfectants. Within the framework of this study, 142 clinical isolates of dermatophytes identified as Trichophyton spp. (n=68) and Microsporum spp. (n=74) were obtained from patients with diagnoses of "B35.3 Mycosis of the feet", "B35.0 Microsporia". It was found that the most active antifungal agents against clinical isolates of dermatophytes are itraconazole, terbinafine and amphotericin B. Among the studied clinical isolates of Trichophyton spp. in Microsporum spp. conditionally resistant strains to the studied antimycotics have been identified. Most of the studied clinical isolates of dermatophytes were high sensitive to antiseptics based on iodine, fucorcinol, undecylenic and boric acids. Disinfectants based on aldehydes, guanidine derivatives, triamines, and glycolic acid showed the greatest activity against clinical isolates of dermatophytes. Based on our data, preference should be given to amphotericin B, itraconazole and terbinafine-based drugs when prescribing ethiotropic therapy for patients with dermatomycosis. It is advisable to use antipseptics and disinfectants for dermatomycosis, taking into account the sensitivity of micromycetes to them.
