Zusammenfassung:Approximately 75% of rural livestock owners in the Eastern Cape province of South Africa use plants or plant based remedies to treat their livestock. Prominent among these plants are Combretum caffrum, Salix capensis and Schotia latifolia. Water, methanolic and acetonic extracts as well as decoctions of the three plants were screened against ten bacteria and five fungi. The results of the antibacterial assay indicated significant activity against all the Gram-positive bacteria tested with the minimum inhibitory concentrations ranging from 0.1 to 5.0 mg/ml. A few of the extracts showed minimal activity, but the majority of extracts were not active on the Gram-negative bacteria. Generally, all the extracts showed some antifungal activity against the five test fungi. Methanolic extracts exhibited higher fungal growth inhibition, whereas the water extracts showed the least inhibition. It was noteworthy that some water extracts promoted fungal growth.
