Following our previous study of the therapy of onychomycosis by non-thermal plasma (NTP) and nail hygiene and to obtain some prerequisite data of dermatophytes sensitivity, the dynamics of those inactivation by NTP plasma was monitored for various strains of Trichophyton iterdigitale, Trichophyton benhamiae, Trichophyton rubrum, and Microsporum canis. Three strains of each species on agar plates were exposed with plasma produced by a DC corona discharge in the point-to-ring arrangement in various time intervals. Although all strains were sufficiently sensitive to plasma action, significant differences were observed in their sensitivity and inactivation dynamics. These differences did not correlate with the species classification of individual strains, but could be assigned to four arbitrarily created types of strain response to NTP according to their sensitivity. These results indicate that the sensitivity to plasma is not an inherent property of the fungal species, but varies from strain to strain.

Dermatophytosis is a superficial skin infection caused by dermatophytes that infected keratinous skin tissue, dermatophytes form molecules that bind to keratin as a source of nutrients in the formation of colonization. Dermatophytes that cause dermatophytosis are Tricophyton sp, Epidermophyton sp and Microsporum sp. To find out the Profile of dermatophytes in patients with dermatophytosis in the Polyclinic of Dermatology and Venerology Dr. Ferdinand Lumbantobing Sibolga in 2019 conducted observational research with cross sectional design. The sample of this study were 75 patients who were new patients and had not used antifungal drugs. This sample is then examined by examination of KOH and cultured and then identified by Scotch-tape Preparation in a microscope. The prevalence of dermatophytosis in this study was 23% of skin cases. The majority of dermatophytosis patients are women (52%), the most age group is 46-65 years (30.7%) and is most often found in housewives (24%). The dermatophytes species found were Trichophyton rubrum, Trichophyton mentagrophytes and Microsporum canis with the most species Trichophyton rubrum (37.3%), which was then followed by Trichophyton mentagrophytes (16%). Tinea corporis, tinea cruris, tinea capitis, tinea pedis and tinea unguinum are dermatophytosis cases that were found in this study. It can be concluded that Trichophyton rubrum is the most common cause of dermatophytosis in Dr. Ferdinand Lumbantobing Sibolga with Tinea corporis is the most classified classification of dermatophytosis.
