Abstract
In continuation to the paper entitled "Saprofitismo do Microsporum canis" presented at the Fifth International Congress for Microbiology, in Rio de Janeiro, in 1940, there are made here new considerations about the probable causes of the appearance of tinea tonsurans and favus. The authors admit the possibility of the existence of the fungi responsible for these mycoses, in saprophitic condition, both in man and animal. They admit, as probable natural causes for the cure of these mycoses in puberty, not only the occurence of the sexual hormones, but also a fatty acid, the pelargonic acid, which is from 4 to 5 times more abundant in the hair of adults than in those of children and which appears with puberty. It is up to the research workers, who are studying this subject, to prove to which of these two agents there is to be attributed the cure of the mycological process and to demonstrate the relation which exists between them.References
