Biological Relationships between Paracocidiodes , Blastomyces and Histopathology

Abstract

Gilchrist in 1896 (69), found the producer microorganism American Blastomycosis in skin sections of tuberculous appearance was in 1898 and Gilchrist and Stokes ( 70 ) the first grown from a case called vulqcrís pseudo - lupus identification of the fungus Blastomyces dermatitidis as for his morfolócícos characters and their pathogenicity in animal experience. Darling , in 1906 and 1909 (38, 39 ) , describes the cause of a like Histop1asmosis intracellular Leishman - Donovan bodies of Kalazar protozoan , giving the generic name of Histoplasma capsulatum , due to its encapsulated ovoid morphology. Da Rocha Lima ( 40 ) , supposed to be a fungus and De Monbreun (42, 43 ) , and Hansma Schéilken ñ ~ (77), the cultured establishing the true nature of the fungus. Demonbreun shows , in turn, the character of the same cultivating dimorphic pathological tissues at two different temperatures , 37 ° C for yeast phase and laboratory temperature to the filamentous phase . Demonbreun ( 42, 43 ) , Redaelli Ciferri and ( 32 ) , Moore ( 107 ) , Conant ( 36 ) , Negroni ( 111, 112 ) , Howell ( 83 ) , describes the morphology and placing fungus sexual cycle into fungi imperfect. Furthermore, in many cases from the African histoplasmosis .
