The tissue grain of Madurella mycetomi infection shows a spread of mineral constituents which is somewhat higher than the known values for the dermis, but differs little in relative concentrations. The unique physical resistance of the grain cannot be related to departures in concentration of calcium or of trace elements. Our earlier hypothesis of a tanned protein structure for the grain therefore still holds (Findlay & Vismer, 1974).
马杜拉足分支菌感染的组织纹理显示矿物质成分的扩散程度略高于真皮的已知值，但相对浓度差异不大。纹理独特的物理抗性与钙或微量元素浓度的偏差无关。因此，我们之前关于纹理为鞣制蛋白质结构的假设仍然成立（芬德利和维斯默，1974年）。
