From: Condensed tannins act as anthelmintics by increasing the rigidity of the nematode cuticle
Mean stiffness of single worms measured via AFM force spectroscopy. Every point represents the mean stiffness of a single worm measured at 3 to 10 different positions. Upper panel: Exemplary force-distance curves for a measuring point on an untreated (a) and a treated (b) worm. The indentation depth is plotted against the applied force. (c) Boxplot showing the maximum, the 75% percentile, the median, the 25% percentile and the minimum. The significant upwards shift of the boxplot of treated worms compared to untreated individuals (p < 0.001) indicates an increase in cuticle stiffness after CM treatment (2 mg/mL, 24 h).
