A new morphologically characterized cell wall preparation (whole peptidoglycan) from Bifidobacterium infantis with a higher efficacy on the regression of an established tumor in mice
Three kinds of morphologically distinct cell wall preparations were isolated from heat-killed Bifidobacterium infantis and examined for the relative antitumor efficacy with syngeneic Meth A fibrosarcoma in BALB/c mice. Ultrastructural examinations revealed that cell wall skeleton (CWS) did not retai …
