Fig. 4From: In vitro effects of aqueous extract from Maytenus senegalensis (Lam.) Exell stem bark on egg hatching, larval migration and adult worms of Haemonchus contortusInhibition of larval migration with the aqueous extract of Maytenus senegalensis without and with polyvinyl polypyrrolidone. Each bar represents mean ± SEM. No significant effects were observed for aqueous extract of Maytenus senegalensis pre-treated with polyvinyl polypyrrolidone (PVPP) (p > 0.05), when compared to aqueous extract without PVPP using Newman-Keuls post test. PBS was used as negative control. Different superscripts indicate significant differences (p < 0. 05) between treatments followed by Dunnett’s post test. M. senegalensis = Maytenus senegalensis. SEM = standard error of mean; PBS = phosphate buffered salineBack to article page
