The author says that, from October 1941 do December 1943, has insulated numerous pathogenic fungi of the most varied lesions. He obtained pure cultures of 5 cases of Rhinocladiosis, 3 of Lutz disease, verified one Actinomyces minutissimus, 2 of Malassezia furfur and 1 Actinomyces, still under study, etc. One of the observations of Sporotrichosis deserves a special reference. It refers to an individual, living in Governador Valadares, who presented a gummy, nodular lesion and verrucoide, fistulous, localized in the umbilical region, caused by the bite of a fish, kind unknown, that attacked the patient when bathing, naked, in the waters of the Rio Doce, State of Minas Gerais. The place of the bite bled slightly and soon after the nodules began to appear, progressively, without affecting the general state of the patient. The sowing of the pus from some of these "nodules" gave pure cultures of Rhinocladium Beurmanni, the only kind the author has insulated up to the present in 55 cases of Sporotrichosis in Minas Gerais. The author had already registered the disease caused by rat-bites, by scratches of rose-thorns, pieces of wood, kitchen knives, blows, etc. He believes, however, this is the first time that the disease caused by the bite of a fich has been recorded. The author refers next to cases of Otomycoses which passed through his hands in 1942, in the service of prof. dr. Ildeu Duarte. He gives a resumé of this observations and concludes they referred to lesionsproduced by, the Aspergillus fumigatus of Fresenius, 1841, according to the histopatological lesions and the cultures he obtained.
