Summary

With high frequency amongst the population, clinical polymorphism and their great contagiousness, mycotic diseases represent an important chapter of medical pathology and a public health problem.

Out of the over 100,000 species of existing microscopic fungi, about one hundred are pathogenic to humans.

From a medical point of view, the fungi are grouped into: dermatophytes, levuriform yeasts or fungi, dimorphic fungi (in vivo lesion form, in vitro filamentous form), opportunistic fungi (pathogens under certain circumstances), actinomycetes (filamentous gram positive bacteri, which produce pseudomycoses).
