Adhesion sites on grass roots for Klebsiella strains carrying type 3 or type 1 fimbriae or both were determined. Adhesion of the strains to the roots of Poa pratensis and Festuca rubra was highly localized; the bacteria adhered strongly to root hairs and with a markedly lower efficiency to the surface of the zone of elongation and to the root cap mucilage. No adhesion to the epidermal cells between root hairs was observed. The adhesion sites were identical for the type 3- and 1-fimbriated bacteria and for P. pratensis, F. rubra, and Trifolium pratense. Inoculation of P. pratensis seedlings with Klebsiella pneumoniae strain As resulted in morphological changes in plant roots. The roots of infected plants were heavily covered with root hairs, which often were deformed and branched.
测定了携带 3 型或 1 型菌毛或两者均有的肺炎克雷伯菌菌株在草根上的黏附部位。这些菌株与草地早熟禾和红羊茅的根的黏附高度局限；细菌强烈黏附在根毛上，对伸长区表面和根冠黏液的黏附效率明显较低。未观察到对根毛之间的表皮细胞的黏附。3 型菌毛和 1 型菌毛以及草地早熟禾、红羊茅和三叶草的黏附部位相同。用肺炎克雷伯菌菌株 As 接种草地早熟禾幼苗导致植物根系发生形态变化。受感染植物的根被大量的根毛覆盖，这些根毛经常变形和分枝。
