Donovanose no Pará
(Universidade Federal do Pará, 1991-12) SALGADO, Ubirajara Imbiriba; NEVES, Cláudio Domingues das; SILVA, Domingos; MACÊDO, Célia
From 1954 to 1990 granuloma inguinale was diagnosed in 259 patients al the dermatology service of the Universidade Federal do Pará in Belém, Brazil. Among them, 56 cases had ocurred in the twenty-year period 1954-1974 and as many as 133 cases were seen during the last five years only. Greater sexual liberty, poor social and economic conditions, and especially increasing homosexual behavior were implicated by the authors as chief determinants for this augmented incidence of the disease.

Isolation of Fonsecaea pedrosoi from thorns of Mimosa pudica, a probable natural source of chromoblastomycosis
(2004-02) SALGADO, Claudio Guedes; SILVA, Jorge Pereira da; DINIZ JUNIOR, José Antônio Picanço; SILVA, Moisés Batista da; COSTA, Patricia Fagundes da; TEIXEIRA, Cláudio Eduardo Corrêa; SALGADO, Ubirajara Imbiriba
We report the isolation of Fonsecaea pedrosoi from thorns of the plant Mimosa pudica L. at the place of infection identified by one of our patients. Clinical diagnosis of chromoblastomycosis was established by direct microscopic examination and cultures from the patient's lesion. The same species was isolated from the patient and from the plant. Scanning electron microscopy of the surface of the thorns showed the characteristic conidial arrangement of F. pedrosoi. These data indicate that M. pudica could be a natural source of infection for the fungus F. pedrosoi.
