Sample A The histopathological findings from an incision biopsy of a cervical lymph node revealed necrotizing granuloma A PCR analysis of a biopsy tissue revealed a positive for MA and a negative for TB (TaqMan)A PCR analysis of a biopsy tissue revealed a negative for MA and a positive for TB (RIT)

Sample BA PCR analysis of an incision re-biopsy of a cervical lymph node revealed a positive for MA and a negative for TB (TaqMan)A PCR analysis of a cultured colony revealed a negative for MA and a positive for TB (TaqMan)A separation of viable bacteria in cultured colonies revealed no MA colonies and all TB colonies
