Species identification of strains belonging to genus Citrobacter using the biochemical method and MALDI-TOF mass spectrometry.

abstract：:Candidiases, infections caused by germination forms of the Candida fungus, represent a heterogeneous group of diseases from systemic infection, through mucocutaneous form, to vulvovaginal form. Although caused by one organism, each form is controlled by distinct host immune mechanisms. Phagocytosis by polymorphonuclea...
