title: Pseudo-outbreak of Clostridium sordellii infection following probable cross-contamination in a hospital clinical microbiology laboratory.
abstract: We report a pseudo-outbreak of infection caused by Clostridium sordellii, an uncommon human pathogen. The pseudo-outbreak involved 6 patients and was temporally associated with a change by the clinical microbiology laboratory in the protocol of handling anaerobic culture specimens. All isolates were genetically indistinguishable from a laboratory reference strain used for quality control.
