 AB    We have shown previously that Listeria monocytogenes, a gram-positive,
       facultative intracellular bacterium, is a potent vector for targeting
       tumor-specific antigens to the immune system. After parenteral
       administration, we observed protection against both renal and colorectal
       mouse tumors and regression of established renal tumors. In the present
       study, we have exploited the fact that the normal route of infection of
       this organism is through the gut. We show that an L. monocytogenes
       recombinant that expresses a model tumor antigen is an effective cancer
       immunotherapeutic agent when delivered orally in that it causes
       regression of established, macroscopic mouse renal and colorectal tumors
       expressing the same antigen.
