In this study, we describe an infant mummy from ancient Egypt that showed macromorphologic signs of chronic anemia and vitamin C deficiency. From this infant, we have obtained a sterile sample from a metatarsal bone to extract ancient bacterial DNA. Following polymerase chain reaction amplification and subcloning of the amplicons, the sequence of the 16S ribosomal DNA was determined in several resulting clones. The presence of pathogenic and apathogenic bacteria, such as Escherichia coli, are indicated by our result, providing evidence of bacteremia, which probably contributed to death due to septicemia. These findings suggest that the infant, who already had chronic anemia and vitamin C deficiency, acquired a gastrointestinal infection, which finally led to a systemic spread. To our knowledge, this is the first case identifying potentially septicemic bacterial dissemination in an ancient Egyptian mummy. Using our approach, we hope to investigate distinct paleomicrobiological aspects of ancient populations, which will potentially enlighten our understanding of the development and evolution of pathogenic bacteria.
