title: Immuno-electron microscopic localization of a choriogonadotropin-like antigen in cancer-associated bacteria.
abstract: The presence of choriogonadotropin-like material and its intimate association with the membranes of the wall of bacteria isolated from cancer patients, has been demonstrated by immuno-electron microscopy utilizing the indirect peroxidase-antiperoxidase-labeled antibody technique. The bacteria were an Escherichia coli strain isolated from a carcinoma of colon, and ATCC 25559 strain of Eubacterium lentum, an anaerobic microorganism originally isolated from a rectal tumor.
