- Osteoarticular tuberculosis (OAT) is an extrapulmonary tuberculosis and accounts for 1 to 3% of all tuberculosis cases. We used an rpoB PCR-plasmid TA cloning-sequencing method to detect and identify tubercle bacilli in surgical specimens from patients suspected of having OAT. By comparing the similarities of the rpoB sequences determined with those in GenBank, Mycobacterium tuberculosis was detected in 23 of 43 samples. Three of the 23 positive samples had mutations at codon 531, which are commonly observed in rifampin-resistant M. tuberculosis strains. Our results suggest that the rpoB PCR-TA cloning-sequencing method developed, which detects M. tuberculosis and which simultaneously determines its rifampin susceptibility, can also be used efficiently for the diagnosis of OAT.
