Abstract
Resistance to Krebs ascites tumour, sarcoma S180 (ascitic form) and PC6 plasmacytoma can be induced with prior immunisation with live Salmonella enteritidis 11RX. One thousand to ten thousand more tumour cells are needed to give an LD50 after immunisation. Resistance to PC6 could be recalled 137 days after intravenous immunisation with 11RX protein antigen intraperitoneally as measured by prolonged survival or monitoring the death of 5[131I]-iodo-2'-deoxyuridine labelled tumour cells in vivo. The range of tumours to which resistance can be produced by 11RX immunisation suggests that the mechanism of resistance does not involve antigens common to the tumours and Salmonella enteritidis 11RX.Keywords
