对43株细菌的形态学进行了研究。通过普通染料染色的固定涂片、鞭毛和荚膜染色、培养物的暗视野检查和培养物的超活体染色，对不同地理和病理来源的土拉热菌进行了研究，证明这种多形生物体是非运动的和无包囊的，其形态单位由扁平和圆柱形的杆状形式、小球、球状体、纤细的丝状体和微小的最小生殖单位组成。其染色质通常位于外周。所有43个菌株在形态上都是相同的。没有变形。发现了区分强毒株和无毒毒株的特征。显然，它具有多种生殖方式，其中芽殖、花丝出芽和以各种方式形成最小生殖单位是最常见的。虽然可能发生分裂，但没有观察到分裂。该物种在生物学上与胸膜肺炎组的关系比任何其他已知的组更密切，尽管明显不同。目前巴氏杆菌、布鲁氏杆菌或球菌的分类是站不住脚的。形态单位用图画和显微照片加以说明。
A morphologic study of 43 strains of Bact. tularense of diverse geographic and pathologic sources by means of fixed smears stained by ordinary dyes, by flagella and capsule stains, by dark field examination of cultures, and by supravital staining of cultures, demonstrated that this polymorphous organism is nonmotile and unencapsulated, and that its morphologic units consist of flattened and cylindrical bacillary forms, globules, globi, delicate filaments, and minute minimal reproductive units. Its chromatin is usually peripherally located. All 43 strains were morphologically identical. No morph. feature was found to differentiate virulent from avirulent strains. Apparently it possesses multiple modes of reproduction, of which budding, pullulatiqn of filaments, and formation of minimal reproductive units in various ways are the commonest. Division by binary fission was not observed, though it may occur. The species is biologically more closely related to, though apparently distinct from, the pleuropneumonia group than to any other group known. The present classification in Pasteurella, Brucella, or Cocco-bacterium are untenable. Morphologic units are illustrated by drawings and by photomicrographs.
