Real-time quantitative PCR in the diagnosis of tuberculosis in formalin-fixed paraffin-embedded pleural tissue in patients from a high HIV endemic area.

The aim of the study was to improve the diagnosis of pleural tuberculosis (TB) based on formalin-fixed biopsies from patients living in high TB and human immunodeficiency virus (HIV) endemic areas. A real-time polymerase chain reaction (real-time PCR) assay targeting a segment of the gene for mycoba
