Direct Detection from Surveillance Swabs, Blood, and Urine Using a Laboratory-Developed PCR Method.

is an emerging fungal pathogen with cases reported in countries around the world and in 19 states within the United States as of August 2020. The CDC has recommended that hospitals perform active surveillance upon admission for patients with the appropriate risk factors. Currently, active surveillance requires that local hospitals send surveillance swabs to a public health laboratory for analysis. In this work, a real-time PCR assay was developed for the specific detection of from surveillance swabs, blood, and urine to enable rapid detection of this pathogen. The assay uses commercially available primers and reporter probes and it was verified on the LightCycler 480 PCR platform. Contrived specimens and prospectively collected composite groin/axilla surveillance swabs were used to validate the assay. The performance of the PCR assay on surveillance swabs was also compared to a second PCR assay targeting that was performed at the Minnesota Department of Health-Public Health Laboratory (MDH-PHL). Our PCR assay is able to detect and differentiate from closely related species such as , , and on the basis of melting curve temperature differences.
