[Fungi in the oro-intestinal tract and their scientifically founded status]

Abstract

The orointestinal tract is a reservoir for facultatively pathogenic fungi, especially Candida albicans. In all of its sections in immunocompromised hosts, the occurrence of a mucosal mycosis is possible which may be the starting point of an infection of internal organs. The mouth and esophagus are the most often affected locations. A synopsis of clinical (including endoscopic) findings, mycological cultivation and mycoserology is important in diagnostics. There is no connection between the incidence of Candida in the orointestinal tract and multiple local symptoms like fatigue, headache, heartburn and others called "candidiasis hypersensitivity syndrome" or "mycophobia".
