Eutypella species Isolated from a BronchoAlveolar Lavage in a Patient with Small Cell Lung Cancer

Abstract

The Eutypella is a genus of fungi in the family Diatrypaceae, and well-known plant pathogens, is capable of infecting manyspecies of maple trees. We introduce here a case of Eutypella species isolated from a bronchoalveolar lavage in animmunocompromised patient with small cell lung cancer initially not suspected by SDA and LPCB stain and revealed by PCRand 18S rDNA sequencing. But, in this case, we couldn't judge whether this fungus was the pathogen for inflammation of lungand additional treatment was not needed for fungus isolation with no clinical problems. The human mycobiome includes 390fungal species detected on the skin, in the vagina, in the oral cavity, and in the digestive tract that includes 335 species and158 genera. Among these, 221 species are found only in the digestive tract, 88 only in the oral cavity, and 26 in both. Thesespecies belong to 126 genera of yeast and filamentous fungi, of the Ascomycota, Basidiomycota, and Zygomycota phyla. So, nomatter how sensitive the diagnosis is, the results of molecular diagnosis method for fungal infection must be carefullyconsidered with clinical conditions..
