In vitro, terbinafine is highly active against a broad spectrum of pathogenic fungi. We evaluated the activities of terbinafine and itraconazole against 31 isolates of Paracoccidioides brasiliensis. The tests were conducted by using a broth macrodilution procedure. MICs, in micrograms per milliliter, were as follows: terbinafine, 0.015 to 1.0 (geometric mean, 0.1188); itraconazole, 0.007 to 0.5...
The archaeal plasma membrane consists mainly of diether lipids and tetraether lipids instead of the usual ester lipids found in other organisms. Although a molecule of tetraether lipid is thought to be synthesized from two molecules of diether lipids, there is no direct information about the biosynthetic pathway(s) or intermediates of tetraether lipid biosynthesis. In this study, we examined th...
We investigated the biochemical basis for resistance in six sequential clinical isolates of Trichophyton rubrum, from the same patient, which exhibited high-level primary resistance to terbinafine. Cellular ergosterol biosynthesis was measured by incorporation of [14C]acetate, and microsomal squalene epoxidase was assayed by conversion of [3H]squalene to squalene epoxide and lanosterol. Direct ...
Topical fungal infections can become severe if left untreated. Efficient treatment modalities for topical fungal infections aid the penetration of antifungal agents deep into viable skin layers. Terbinafine is a fungicidal agent that inhibits ergosterol, an essential fungal component. The main objective of this study was to evaluate skin permeation and retention of a terbinafine-loaded solution...
Candida albicans, the most important opportunistic fungal pathogen, is able to generate remarkable amounts of reactive oxygen species (ROS). Since ROS are highly cytotoxic, this mechanism may contribute to the pathogenicity of this yeast, including its invasiveness and the inflammatory response of the host. Terbinafine, a synthetic antifungal agent of the allylamine class, inhibits ergosterol b...
Synergistic interaction of terbinafine with triazoles or amphotericin B against Aspergillus species.
The in vitro activity of terbinafine alone and in combination with other antifungal agents was tested against isolates of Aspergillus fumigatus, A. flavus and A. niger. Testing was performed in a modified National Committee for Clinical Laboratory Standards (NCCLS) macrodilution broth assay, and interactions were examined using a checkerboard design. Terbinafine was highly active against Asperg...
Chromoblastomycosis is caused by dematiaceous fungi. It develops after inoculation of the organism into the skin. We report a case of chromoblastomycosis in a pulmonary tuberculosis patient without known history of trauma. The lesions were initially diagnosed as sporotrichosis and skin tuberculosis. Histopathology of scales and skin biopsy specimen revealed sclerotic bodies, the hallmark of chr...
BACKGROUND The patient was aged 34 when he consulted a dermatologist in Vancouver BC with onychomycosis affecting the right great toenail. CASE PRESENTATION Trichophyton rubrum was cultured from nail clippings. Griseofulvin was taken for 6 months, resulting in clinical and mycological cure. Over the next 27 years there were multiple relapses. Each course of treatment with oral terbinafine (fo...
A previously healthy man, 43 years of age, was referred to the dermatology department with a one-year history of fingernail onychomycosis. His condition was refractory to oral antifungal treatment (terbinafine 250 mg QD for three months). On physical examination, nail pitting and onycholysis affecting seven fingernails was noted (Figure 1A). He also had mild erythematous silvery-white scaly pat...
