摘要
本文继25种标准菌株形态学观察与菌体测量之后,对16例肺结核患者的痰直接涂片及其分离菌株涂片进行了观测。其中发现不少失去抗酸性菌体。G_(244)号标本培养菌株呈典型的索状生长。菌体表现为多形性,分离菌株涂片较直接涂片更为突出,且前者含有更多的异染颗粒,其数目、大小及位置不等。直接涂片不少菌体位于细胞内。菌体测量表明来自感染组织的细菌(直接涂片),较试管内生长者(同一标本的分离菌株涂片)的菌体明显增长。
The morphology of standard strains of 25 species of mycobacteria was tsudied.On Lowenstein-Jensen medium,the colonies of mycobacteria tuberculosis complehwere mostly of rough type,while the atypical mycobacteria were mostly of smootxtype.Part of the strains of the later was of mucous type,with some strains of themproducing pigments from yellow to brick-red in color.Typical cord arrangementof H37Rv was seen and branch growth of Mycobacteria Fortuitum was revealed bydirect smear under microscope.The number,size and position of the metachromaticgranules varied,and a number of them had some unknown blue ring-form substan-ces.20 bacilli of each species were measured by micrometer in smear at random,withthe mycobacteria tuberculosis complex ranging in size from 0.291～2.037 by 0.776～3.395μm and atypical mycobacteria from 0.388～1.649 by 0.582～6.110μm.Comparedthe cold stain method with the conventional hot stain one,no significant differenceswere found among all the species.
