Preservation and identification of ancient M. tuberculosis complex DNA in Egyptian mummies
For years we have investigated the presence and molecular evolution of tuberculosis in Pre Dynastic and Early Dynastic Egyptian mummy material from Abydos (c. 3500-2800 BC), Middle and New Kingdom until the Late Period in Thebes-West (c. 2050 – 500 BC). We have analysed 160 bone and soft tissue samp...

| Summary: | For years we have investigated the presence and molecular evolution of tuberculosis in Pre Dynastic and Early Dynastic Egyptian mummy material from Abydos (c. 3500-2800 BC), Middle and New Kingdom until the Late Period in Thebes-West (c. 2050 – 500 BC). We have analysed 160 bone and soft tissue samples from different time periods and populations for the occurrence of M. tuberculosis complex DNA. All positive specimens were genetically characterised by spoligotyping and mutation analysis. Molecular analyses revealed excellent state of preservation of the specimens. Research showed a high incidence of M. tuberculosis during all time periods. We further detected specific MTB strain differences with M. africanum in some of the Middle Kingdom samples and “modern” M. tuberculosis strains in the New Kingdom to Late Period material. These results demonstrate that aDNA is excellently preserved in ancient Egyptian mummies allowing the reconstruction of occurrence, frequency, molecular evolution and spread of tuberculosis in Pharaonic populations. |
