很早就证明,伪结核菌和大肠菌噬菌体在形态学和血清学上有相似性。本文采用了5株伪结核菌噬菌体(PST、3M、,以及早先不曾研究过的2344和2391),4株大肠菌噬菌体(T_2、T_4、T_3和 T_7),1株痢疾菌噬菌体(DD Ⅵ)。用下列菌株研究了噬菌体的特异性及作用范围:伪结核菌100株,鼠疫杆菌98株,痢疾菌25株,大肠菌116株。用伪结核菌及大肠菌噬菌体制备抗噬菌体血清。用抗噬菌体血清同噬菌体做 It has long been demonstrated that both M. tuberculosis and coliforms are morphologically and serologically similar. Five strains of Pseudomonas sp. (PST, 3M, and 2344 and 2391, which were not previously studied), four strains of coliforms (T_2, T_4, T_3 and T_7) and one strain of dysentery bacteriophage (DD Ⅵ) . The phage specificity and scope of action were studied with the following strains: 100 strains of Pseudomonas sp., 98 strains of Yersinia pestis, 25 strains of dysentery and 116 strains of coliforms. Antibacterial sera were prepared using pseudotuberculosis and coliforms. Use anti-phage serum to do with phage
