RT Journal Article SR Electronic T1 Relative carriage rates of nuclear dehydrogenating clostridia in two populations of different colorectal cancer risk JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 93 OP 95 DO 10.1136/jcp.36.1.93 VO 36 IS 1 A1 SP Borriello A1 BS Drasar A1 A Tomkins A1 MJ Hill YR 1983 UL http://jcp.bmj.com/content/36/1/93.abstract AB Carriage of nuclear dehydrogenating clostridia has been associated with colon cancer and implicated in its aetiology. This study has compared the carriage of these organisms in a British population at high risk for the development of colon cancer with a low risk Nigerian population. Clostridia were found in all of the stools from both populations. Nuclear dehydrogenating clostridia were only found in the stools of the British subjects (32%). These results support the suggestion that the carriage rate of nuclear dehydrogenating clostridia in a population is related to the risk of colon cancer.
