One hundred eleven clinical Trichophyton rubrum isolates were tested against 7 antifungal agents. The geometric mean MICs of all isolates were, in increasing order: terbinafine, 0.03 mg/liter; voriconazole, 0.05 mg/liter; posaconazole, 0.11 mg/liter; isavuconazole, 0.13 mg/liter; itraconazole, 0.26 mg/liter; griseofulvin, 1.65 mg/liter; and fluconazole, 2.12 mg/liter.
Genotypic variability among 96 Trichophyton rubrum strains which displayed different colony morphologies and were collected from four continents was investigated. Twelve markers representing 57 loci were analyzed by PCR fingerprinting, amplified fragment length polymorphism, and random amplified monomorphic DNA markers. Interestingly, none of the methods used revealed any DNA polymorphism, indi...
OBJECTIVES Arthroconidia have been considered as the primary cause of infection by dermatophytes. However, the in vitro antifungal testing evaluates the responses mainly of microconidia or hyphae, and dermatophytes in vivo often produce arthroconidia, a cellular structure presumably more resistant to antifungals. The aim of this study was to compare the in vitro susceptibility of microconidia a...
The value of direct microscopy and cultural tests in onychomycosis is reported on the results of the examination of 3,955 nail collections from patients infected with Trichophyton rubrum. Of the total number of mycological diagnoses, 15% would have been missed if culture had been omitted and 53% if direct microscopy had not been undertaken.
We have characterized a new clinical strain of Trichophyton rubrum highly resistant to terbinafine but exhibiting normal susceptibility to drugs with other mechanisms of action. Resistance to terbinafine in this strain is caused by a missense mutation in the squalene epoxidase gene leading to the amino acid substitution F397L.
Background Trichophyton rubrum is a dermatophyte that causes mostly superficial mycoses in skin, hair and nails, but an invasive course has been described in immunocompromised patients [1]. The resistance to usual antifungal drugs has been observed in T.rubrum what drives an increasing demand for new antifungal drugs. Chalcones are flavonoids found in plants that exhibit pronounced antifungal a...
BACKGROUND Trichophyton rubrum represents the most common infectious fungus responsible for dermatophytosis in human, but the mechanism involved is still not completely understood. An appropriate model constructed to simulate host infection is the prerequisite to study the pathogenesis of dermatophytosis caused by T. rubrum. In this study, we intended to develop a new T. rubrum infection model ...
