Diagnosis of Pneumocystis carinii pneumonia by 5S ribosomal DNA amplification.

Abstract

The polymerase chain reaction technique was used to detect Pneumocystis carinii by amplifying the P. carinii 5S ribosomal DNA. The efficacy and specificity of this diagnostic method is reported. Analysis of patients' sputa indicate that the method can be used on these samples for the diagnosis of P. carinii pneumonia.
