Kazachstania slooffiae, an emerging pathogen to watch for in humans?

Abstract

In an 80-year-old man with long-term dysphagia, an upper endoscopy was performed and biopsy samples collected for microbiological and pathological tests, showing fungal structures. Kazachstania slooffiae was isolated in microbiological cultures that were later confirmed with DNA sequencing. Susceptibility tests were performed, and antifungal treatment was initiated with a clinical, pathological, and microbiological response.
