Evaluation of the antibacterial and hemolytic activities of Latvian herbal preparation.

Three extracts originating from a combination of various Latvian plant species were tested for their antibacterial activities by evaluating growth delays using a fully automated microturbidimetric method. Ten different human and bovine strains of the genera Staphylococcus and Micrococcus were used as test microorganisms. The inhibitory effect in vitro was defined as the difference between the growth rate without herbs and the growth rate in the presence of an extract.
