Seven human skeletons from a large assemblage from a rural English Medieval burial site show lesions, predominantly proliferative in nature, on the visceral surfaces of the ribs. In order to investigate whether these rib lesions were regularly associated with tuberculous infection, these individuals, together with a group of age- and sex-matched control skeletons without bony signs of infection, were subjected to polymerase chain reaction (PCR) assays aimed at detecting traces of DNA from infecting microorganisms of the Mycobacterium tuberculosis complex. The results provided no evidence for any regular association between visceral surface rib lesions and the presence of M. tuberculosis complex DNA in the study group. The significance of these findings for the paleopathological interpretation of visceral surface rib lesions is discussed.
