Antitumor activity of a Brucella abortus preparation.

RESUMO

Mice injected intraperitoneally with sarcoma-180 cells develop ascites and eventually die. Intraperitoneal injection of a nonviable, aqueous... ether-extracted Brucella abortus preparation (BRU-PEL) as early as 7 days before or as late as 7 days after injection of tumor cells significantly inhibited development of ascites and protected against death. BRU-PEL was not effective if injected after ascites was grossly apparent. BRU-PEL was significantly more active than a Corynebacterium parvum preparation administered in the same way.
