Abstract

Ralstonia mannitolilytica, an opportunistic pathogen commonly present in water, was identified in three hospitalized patients over a short period of time. The comparison of draft genomes of 12 isolates from patients and water sprays showed fewer than 10 single-nucleotide polymorphisms, indicating that water sprays were the contamination source.
