Genomic reconstruction of an azole-resistant Candida parapsilosis outbreak and the creation of a multi-locus sequence typing scheme: a retrospective observational and genomic epidemiology study.

Fluconazole-resistant Candida parapsilosis has emerged as a significant health-care-associated pathogen with a propensity to spread patient to patient and cause nosocomial outbreaks, similar to Candida auris. This study investigates a long-lasting outbreak of fluconazole-resistant C parapsilosis that was initially detected in December, 2018, and January, 2019, and officially declared in November, 2019; lasted multiple years; and involved several health-care centres in Berlin, Germany.
