The author focused this studies on transport medium for pasteurella pneumotropica and morphology of the bacteria. The ability of leibovitz medium no. 15 with 0.5% agar (L-15 transport medium), phosphate medium (0.3% disodium phosphate ), and Cary-Blair medium to preserve the viabilities of 3 P.pneumonia strains was studied. L-15 transport medium was found to be superior to the other media, enabling survival of organism for more 7 days at room temperature without decreasing the numbers of viable P.pneumotropica. The structures of cell surfaces with the strains of P.pneumonia from mouse and rat were studied by transmission electron microscopy with or without polycationic ferritin labeling. The 3 strains of P.pneumotropica, isolates of mouse, rat, and reference strain from mouse, ATCC 35149 , have characteristic cell surfaces of gram negative bacteria. There are differences between mouse and rat strains. Many bacteria cells of rat strain were dead, whereas those of mouse strains were good survived. Furthermore, biological and biochemical properties of the strains were investigated. All strains were identified as type Jawetz.

作者着重对嗜肺巴氏杆菌的转运培养基和菌体形态进行了研究。研究了含0.5%琼脂的15号Leibovitz培养基（L-15转运培养基）、磷酸盐培养基（0.3%磷酸二钠）和Cary-Blair培养基保存3种肺炎支原体菌株活力的能力。L-15运输介质被认为是上级其他媒体，使生存的有机体在室温下7天以上，而不减少可行的嗜肺假单胞菌的数量。本文用透射电镜观察了小鼠和大鼠肺炎杆菌的细胞表面结构。嗜肺假单胞菌的3种菌株（小鼠、大鼠分离株和小鼠参考菌株ATCC 35149）具有革兰氏阴性菌的特征性细胞表面。小鼠和大鼠品系之间存在差异。大鼠品系的细菌细胞大量死亡，而小鼠品系的细菌细胞存活良好。并对菌株的生物学和生化特性进行了研究。所有菌株均鉴定为Jawetz型。
