In order to standardize a polymerase chain reaction (PCR)-based method of Pneumocystis detection, we describe the development of an improved PCR method that targets the Pneumocystis mtLSUrRNA gene. Design of a new primer pair and PCR program with suitable parameters and optimization resulted in a simpler and faster single-round amplification assay. The sensitivity of the novel Pneumocystis genus-specific PCR proved comparable to the reference nested PCR. The improvement that this new PCR assay offers in the detection and epidemiological studies of Pneumocystis spp. infection in research laboratories is discussed.
Keywords: PneumoDB; Pneumocystis spp.; mtLSUrRNA; single-round PCR.
