Abstract

Community acquired pneumonia (CAP) due to Streptococcus pneumoniae still occurs in at risk populations, despite the availability of effective vaccines. Laboratory confirmation of S. pneumoniae remains challenging in cases of CAP despite advances in blood culture techniques and the availability of nucleic acid amplification tests such as PCR-based methods. Urine specimens are an attractive sample type because they are non-invasive compared to bronchial washes or whole blood specimens for patients with CAP. While urine specimens have been used successfully in antigen detection assays, they have not been extensively evaluated for PCR-based assays. In this preliminary study, we evaluated the potential for a real-time PCR assay targeting the S. pneumoniae autolysin gene (lytA) to detect in archived urine samples from patients with CAP. Results indicate that the real time lytA PCR assay on the Luminex ARIES® system shows promise as a screening tool for patients with CAP based on comparison to urine antigen detection assay results.
