Figure 5From: Assessment of the anthelmintic activity of medicinal plant extracts and purified condensed tannins against free-living and parasitic stages of Oesophagostomum dentatumEffects of condensed tannins on motility and morphology of adult Oesophagostomum dentatum. A - Inhibition of O. dentatum adult motility by hazelnut skin extract. Results are from a single experiment performed in triplicate. B - Transmission-electron microscopy of thin sections of adult worms exposed to only medium (‘control’) or 1 mg/mL of hazelnut skin extract (‘CT’) for 24 hours. ‘cu’ - cuticle; ‘hy’ - hypodermis. Note the rough cuticle in worms exposed to CT (black arrows), and rupture and detachment of the hypodermis (white arrows). Scale bar =2 μM.Back to article page
