Antifungal sensitivity and species of yeasts in oral mucosa of street mixed-breed dogs

The aim of this research is to verify the yeast species isolated from oral mucosa in street mixed-breed dogs and to determine the antifungal profiles. After capturing and sedating the animals, oral mucosa samples were collected from fifty dogs and the materials were inoculated on Sabouraud dextrose agar with chloramphenicol. Forty-three yeast strains were isolated and identified trough the API-20C AUX method. Thirty-seven (86.1%) of the yeasts belonged to genus Candida, five (11.6%) to genus Trichosporon and only one strain (2.3%) to genus Malassezia. The sensitivity profiles to anifungals (amphotericin B, itraconanole, ketoconazole, fluconazole and variconazole) were determined through Etest® method. This study found resistance of some yeasts to amphotericin B and a good susceptibility to voriconazole and ketoconazole. Some of these antifungals are used in veterinary medical practice. This research is the first investigation on street mixed-breed dogs regarding yeast identifications and antifungals profiles.
