Chromoblastomycosis is one of the most prevalent implantation fungal infections caused by melanized fungi, affecting individuals with certain risk factors with high morbidity due to its recalcitrant nature. It is difficult to identify the etiological agents and thus a suitable reproductive molecular identification method applicable in developing countries has been investigated. We report the identification of four different fungal causative agents of chromoblastomycosis by reverse line blotting hybridization (RLB) based on biotin-labeled PCR products and amine labeled probes to hybridize.

Westerdijk Fungal Biodiversity Institute, Utrecht, The Netherlands.

Black yeasts (BY) comprise a group of polyextremotolerant fungi, mainly belonging to the order Chaetothyriales, which are capable of colonizing a wide range of extreme environments. The tolerance to hostile habitats can be explained by their intrinsic ability to survive under acidic, alkaline, and toxic conditions, high temperature, low nutrient availability, and osmotic and mechanical stress. Occasionally, some species can cause human chromoblastomycosis, a chronic subcutaneous infection, as well as disseminated or cerebral phaeohyphomycosis. Read More
