Fig. 2From: Microbiology of secondary infections in Buruli ulcer lesions; implications for therapeutic interventionsAcid-fast and PCR positivity among the suspected BU cases. All patient lesion samples were screened for the presence of acid-fast bacteria, mycobacterial 16SrRNA and IS2404 gene amplification for BU case confirmation. A higher positivity rate was observed for PCR (16SrRNA & IS2404) compared to direct smear microscopy (detection of acid-fast bacilli) for the confirmation of BU casesBack to article page
