Abstract

This study attempted to determine the effect of lyophilized sap from Musa acuminata Colla on “in vitro” activation of peritoneal macrophages and antibody production in BALB/c mice infected with Escherichia coli O157:H7. Macrophage activation was determined by phagocytic index and microbicidal activity of murine peritoneal macrophages which were distributed in three groups: experimental A and experimental B, both had different concentrations of lyophilized sap (SLM), while control group had minimal essential medium. After that, we added E. coli O157:H7, so the concentration of SLM was 16,3 ug/mL in experimental A and 8,75 ug/mL in experimental B. Then we took samples in order to determine the phagocytic index and microbicidal activity. Antibody production was studied in BALB/c mice randomly allocated in three groups: experimental A, experimental B and control. Experimental A and B were orally administered with SLM at 20 mg/kg and 10 mg/kg respectively, control group was administered with sterile normal saline. They were infected with E. coli O157:H7 and then blood samples were collected in order to determine the antibody titer. Results showed that macrophages stimulated with SLM at 8,75 ug/mL had an increasing phagocytic index compared with the others. Besides microbicidal activity and antibody titer obtained in both experimental A and B were higher than control group. As a conclusion, lyophilized sap from Musa acuminata Colla increases phagocytic index, microbicidal activity and antibody production in BALB/c mice infected with Escherichia coli O157:H7.
