Scanning electron microphotographs of B. glabrata mantle. a, b The normal ultrastructure of B. glabrata mantle. There are dense protuberances or spines regularly covered with microvilli on the surface of the mantle (b, arrow). c, d Most microvilli were completely destroyed (d, arrow) and the rough surface was exposed after a 24-h exposure to 0.070 mg/l niclosamide. e, f The collapsed microvilli of the mantle were distributed irregularly after a 24-h exposure to 0.261 mg/l salicylanilidate (f, arrow)
