The study of mycotic diseases has been regarded with indifference between us. Apart from the interesting work Escomel on Blastomycosis, our literature no comments on this important issue. Yet the conditions caused by fungi have become of considerable importance in pathology. A number of conditions, arbitrarily considered arthritic, syphilis or tuberculosis, have a micósico origin; at the expense of fungi have enlarged the picture of our etiologic agents.

In late 1905, my friend Dr. M. Aljovín told me to examine a patient who had for a long time, a pustular rash on the upper lower é members. As a result of the tests I did, I found an undescribed fungus, which in all probability was the pathogen of the injury.

Brumpt created in 1911 for certain Gender Grahamella bacillary aspect bodies found in the interior of red blood cells and some animals were observed and described for the first time in 1905 by GRAHAM SMITH  in blood moles (Talpae) captured in Cambridge (England). Later these bodies have been observed and studied by Thomson and Balfour in 1906, by FRANCA and Brumpt in 1911, by Leger Prowazek, HENRY, JOYEUX and VISENTINI  in 1913 by Laveran and MARULLAZ, Scott Macfie, DUDTSCHENKO and COLES in 1914, by Carini  in 1915 and YAKIMOFF in 1917.
