Objectives: The analysis of the prevalence and characteristics of fungi colonising various ontocenoses of the upper alimentary tract (orał cavity, oesophagus, stomach, duodenum, anus) in children infected by Helicobacter pylori. Material and methods: The study was performed in 48 children. During endoscopy the contents of the oesophagus, stomach and duodenum were collected with aseptic catheters, and additionally washings from the orał cavity and anal swabs or samples of faeces. Materials were inoculated on Sabouraud's media. The fungal strains were identified using API 20 C.API 20 C AUY and API ZYM tests according to the principle of numerical identification (Analytical Profile Index, BioMerieux, Lyon 1990). Results: Among 48 studied children, the presence of fungi wasfound in 40 cases (83.3±5.4%). In the majority of children (82.5±5.5%) mycotic invasions were multifocal, colonising 2-5 ontocenoses. The dominating species was Candida albicans; there was also C. kefyr, C. famata, C. glabrata, C. tropicalis. 5 different codes of C. albicans with the high activity of several hydrolases (Leucine arylamidase, Phosphatase acid) were identified. Conclusions: The prevalence of fungi in the upper alimentary tract in children infected by Helicobacter pylori was high (73.9±6.3%). Mycotic invasions were multifocal. The dominating species was Candida albicans (93.6±2.3%). There were significant biochemical intraspecies differences among isolated fungi strains.
