Fig. 3From: Differential expression of hemolysin genes in weakly and strongly hemolytic Brachyspira hyodysenteriae strainsDepiction of hemolysis of culture filtrates of strongly (left) B. hyodysenteriae strain B204 (left) and weakly B. hyodysenteriae strain G423 (right) by using a hemolysis diffusion test. For semi-quantitative estimation of the hemolytic activity the hemolysis zone was measured (in mm)Back to article page
