BACKGROUND The largest outbreak of sporotrichosis occurred between 1938 and 1947 in the gold mines of Witwatersrand in South Africa. Here, we describe an outbreak of lymphocutaneous sporotrichosis that was investigated in a South African gold mine in 2011. METHODOLOGY Employees working at a reopened section of the mine were recruited for a descriptive cross-sectional study. Informed consent w...

online | memorias.ioc.fiocruz.br Sporothrix schenckii is a dimorphic fungus that is responsible for cutaneous disease in endemic areas worldwide. Classically, infection is associated with a traumatic subcutaneous inoculation of contaminated soil, plants or organic matter. The most common clinical form of sporotrichosis is cutaneous, lymphatic disease, which accounts for 75% of cases, followed b...

Sporotrichosis is a subacute or chronic mycosis caused by a fungus of the genus Sporothrix, which is found in soil. It can be acquired by trauma to the skin. Bone and joint lesions are very rare. The city of Rio de Janeiro is undergoing an epidemic transmitted by cats, and this should be an alert for the risk to professionals in contact with these animals. The patient was a veterinarian who dev...

Crude extracts and fractions of five species of Polygala - P. campestris, P. cyparissias, P. paniculata, P. pulchella and P. sabulosa - were investigated for their in vitro antifungal activity against opportunistic Candida species, Cryptococcus gattii and Sporothrix schenckii with bioautographic and microdilution assays. In the bioautographic assays, the major extracts were active against the f...

Clinical and microbiologic aspects of fungal sinusitis occurring in six patients are presented. Three of the six patients were immunosuppressed. Fatal disseminated fungal disease developed in two of those immunosuppressed. The three patients with normal immune function had fungal infections confined to the nasal sinuses. Aspergillus fumigatus and Aspergillus flavus were recovered from the immun...

Cellulolytic enzyme preparations active against various forms of cellulose have been reported by a number of investigators who have used a variety of different sources (8). Fungi which have been employed for the preparation of such extracts are Sporotrichum cards (15), Aspergillus oryxae (3,2), Merulius lachrymans (9), and Coniophora cerebella (7), while bacteria have included Bacterium protoxo...

The viability, morphological characteristics and dimorphic ability of fungi were evaluated. Strain subcultures were maintained under mineral oil and in soil for different periods of time, ranging from 49 to eight years. Of the 16 Blastomyces dermatitidis strains, four maintained viability and were able to complete the dimorphic process to the M phase producing a large amount of conidia, but wer...
