Saprochaete clavata Outbreak Infecting Cancer Center through Dishwasher.

Saprochaete clavata Outbreak Infecting Cancer Center through Dishwasher. Emerg Infect Dis. 2020 Sep;26(9):2031-2038 Authors: Menu E, Criscuolo A, Desnos-Ollivier M, Cassagne C, D'Incan E, Furst S, Ranque S, Berger P, Dromer F Abstract Saprochaete clavata is a pathogenic yeast responsible for rare outbreaks involving immunocompromised patients, especially those with hematologic malignancies. During February 2016-December 2017, we diagnosed S. clavata infections in 9 patients (8 with fungemia), including 3 within 1 month, at a cancer center in Marseille, France. The patients (median age 58 years), 4 of 9 of whom had acute myeloid leukemia, were hospitalized in 3 different wards. Ten environmental samples, including from 2 dishwashers and 4 pitchers, grew S. clavata, but no contaminated food was discovered. The outbreak ended after contaminated utensils and appliances were discarded. Whole-genome sequencing analysis demonstrated that all clinical and environmental isolates belonged to the same phylogenetic clade, which was unrelated to clades from previous S. clavata outbreaks in France. We identified a dishwasher with a deficient heating system as the vector of contamination. PMID: 32818391 [PubMed - in process]
