Pseudo-outbreak of Brevundimonas diminuta Attributed to Contamination of Culture Medium Supplement.

We report an epidemiological investigation of a cluster of Brevundimonas diminuta isolates cultured from sterile sites. Inoculation of supplement medium yielded growth of B. diminuta. Molecular typing indicated likely contamination of the lot. No B. diminuta was further isolated after replacement of the supplement with a new lot number.
