We report a cluster of 9 isolates of Parengyodontium album recovered from 4 patients who had surgical tissue specimens processed after dilution with a multiuse diluent saline solution. P album was also identified from a nonclinical sample on agar prepared with the same lot number of saline solution. Our epidemiological investigation revealed this to represent a pseudo-outbreak related to contaminated saline used to process specimens in the microbiology laboratory.
