Abstract
The structure and reproduction of Paracoccidioides brasiliensis (Splendore) Almeida, the causal agent of South American Blastomycosis, were studied under the electron microscope, in material taken from human tissue. The yeast-like cells of the fungus show all major cellular components. The reproduction of the organism is accomplished by two kinds of sporulation. One is represented by regular budding observed in yeasts or yeast-like organisms, with formation of chains of cells. The other is characterized by production of numerous small blastospores around the mother cell and presenting an appearance in optical median section of a fan or of a ship's steering wheel. A estrutura e reprodução de Paracoccidioides brasiliensis (Splendore) Almeida—o agente causal da Blastomicose Sul-americana—foram estudadas sob o microscópio eletrônico, baseado em material removido de tecido humano. As células leveduriformes do fungo exibem os componentes celulares clássicos. A reprodução do organismo é feita por dois processos de brotamento. Um é o regularmente observado nas leveduras e células leveduriformes, com formação de cadeias de blastosporos. No outro, há formação de numerosos e pequenos blastosporos ao redor da célula em reprodução e o conjunto fica com o aspecto de roda de leme, quando examinado em corte óptico mediano.Keywords
