Candida albicans is the most prevalent fungal pathogen in humans. It is the causative agent and most associated with serious fungal infection, accounting for more than 90% of cases. It is a most common cause of deep mycoses and vulvovaginal candidiasis. In the present study we found that methanolic extract of O. sanctum in combination of fluconazole shows higher zone of inhibition and lesser MIC values as compared to methanolic extract of leaves of O. sanctum or fluconazole when used alone. Synergistic antimicrobial activity was found when methanolic extract of leaves of O...

Fungal otitis (otomycosis) is a common infection encountered by otolaryngologists. Nevertheless, its management can be challenging because of its high recurrence rate and of the limited therapeutic options. A 45-year-old woman suffered from recurrent otomycosis. The ineffectiveness of successive antibiotic cures and repeated topical treatments with nystatin and then with econazole cream led to perform microbiological analyses. Culture of ear swab grew Aspergillus niger. The use of a 1% voriconazole sterile solution previously validated for treatment of eye infections was considered after ensuring the absence of known ototoxic effects of the antifungal and of the excipients...

Skin and soft tissue infections (SSTIs) are very common in dermatology and the use of antimicrobial formulations are important in treating these diseases. With the increasing of drug-resistant strains, researchers need to find ways to enhance the effectiveness and/or reduce the drug resistance. Clioquinol was one of antiseptics that can inactivate microbes. It was lack of data of antimicrobial activity; meanwhile it was infrequently used in infection. In order to research the antimicrobial spectrum and activity of topical 3% clioquinol cream among common pathogenic microorganisms compared with other common topical pharmaceuticals, we used modified agar diffusion assay to judge drug susceptibility and compared with broth microdilution assay...

Traditional, culture based methods for the diagnosis of fungal infections are still considered as gold standard, but they are time consuming and low sensitive. Therefore, in order to overcome the limitations, many researchers have focused on the development of new immunological and molecular based rapid assays that could enable early diagnosis of infection and accurate identification of fungal pathogens causing superficial and invasive infection. In this brief review, we highlighted the advantages and disadvantages of conventional diagnostic methods and possibility of non-culture based assays in diagnosis of superficial fungal infections and presented the overview on currently available immunochromatographic assays as well as availability of biomarkers detection by immunodiagnostic procedures in prompt and accurate diagnosis of invasive fungal infections...
