Abstract

Over recent years non-culture techniques such as specific viral and bacterial nucleic acid amplification, serology and antigen detection have considerably developed and been applied within research studies to clinical samples, significantly increasing pathogen detection in pneumonia. There are promising signs of improved diagnostic yields for pneumococcal pneumonia when using molecular techniques to detect pneumococcal gene sequences in blood or by combining serum biomarkers with rapid pneumococcal urinary antigen testing. Pathogens have traditionally been difficult to detect in pneumonia and treatment is usually successful with empiric antibiotics. However, directed antibiotic treatment has significant benefits in terms of antibiotic stewardship and these new technologies make this goal a possibility, though not yet a reality.
