Phylogenetic tree representing patients hospitalized with invasive Serratia marcescens infections and whole-genome sequencing for environmental and clinical isolates at prison A, California, USA, January 2020–March 2023. The predominant outbreak cluster included patients A, B, D, E, K, M, O, and R and environmental samples C (needle/syringe) and sample I (nasal spray bottle) from patient D. These sequences had 0–19 single-nucleotide polymorphism (SNP) differences. Patient F, sample B (coffee cup) found in patient D’s cell, sample H (hand rinsate) from the cellmate of patient D, and sample Y (doorway swab) from the cell occupied at different times by both patient A and AC are grouped together within a 11–17 SNP range.
