Abstract:
Objective To investigate the clinical manifestation and the characteristics of laboratory examinations of invasive Scedocporium infection.Methods The clinical data of 8 patients infected with Scedosporium from January 2011 to April 2017 were collected and retrospective analysis combined with related literatures was performed.Results Among the 8 patients,6 strains of S.apiospermum,1 strains of Peudallescheria boydii and 1 strains of S.prolificans were detectable.The predisposing factors of Scedosporium infection were trauma,environmental exposure and hypoimmunity.The septahypha in specimens could be direcdy observed under microscopic examination with positive rate 100％.The growth speed of cultured colony was relatively fast and the invasiveness was strong.The colony of Scedosporium displayed various forms from white cashmere to black yeast sample.The color was gradually become dark from the center of colony with lengthening time of cultivation.Scedosporium could be identified by microscopic morphology combining culture technique.Conclusion The course of invasive Scedosporium infection may progress rapidly with serious and dangerous illness state.The most common infection of Scedosporium should be induced by S.apiospernum.The knowledge and understanding for Scedosporium infection should be strengthened to improve the level of diagnosis and treatment.
