Inhibición del enquistamiento de Entamoeba histolytiea por Laetoeoeeus laetis Inhibition on encystation of Entamoeba histolytica by Lactoccocus lactis

Amoebiasis is caused by Entamoebahistolytica, a protozoan parasite that has two stages in its lile cycle: the trophozoite (invasive stage) and cyst (inlective stage and resistance). The drug 01choice in their treatment is metronidazole, however, this drug in human s has many undesirable side effects, so it is necessary to find new therapeutic alternatives. WHO has proposed the use 01microarganism slar the design 01microbial interlerence therapy.ln this study we evaluated under axenic conditions in vitro Lyophilized conditioned medium (LMC) 01 Lactococcus lactis (L1) on encystment 01 E. histolytica. The results showed significant inhibition on encystation stage 01E. histolytica.
