Figure 4: Toxicity assessment of anti-MRSA molecule C23 from S. rubrolavendulae ICN3. (a) Arrows indicating the bradycardia and trunk flexure at 50 μg/ml. Scale bar 150 μm (2 dpf). (b) Trunk flexure and yolk sac oedema at 50 μg/ml. Scale bar 100 μm (2 dpf). (c) Untreated embryo. Scale bar 100 μm (2 dpf). LC50 was determined by probit analysis as 60.49 μg/ml (with 95% Confident limit). The lower and upper limits were calculated as 54.51μg/ml - 66.08 μg/ml.
