Comparative analysis of the leprosy detection rate regarding its clinical spectrum through PCR using the gene: a scientometrics and meta-analysis.

Background: Leprosy is a chronic and disabling infectious disease caused by . It has a wide clinical spectrum and is operationally classified into paucibacillary (PB) and multibacillary (MB) cases. There is evidence that the gene can be used in Polymerase Chain Reaction (PCR) for complementary detection with high sensitivity and specificity.
