摘要
本文应用裂解气相色谱法分析15株伤寒沙门氏菌(其中标准株1株,临床株14株)的色谱图,结果表明,临床株裂解气相色谱图分为A和B两类。A类(7株)色谱图完全相同;B类(7株)色谱图仅相似,但按其差异又可分为B_1组(4株),B:组(2株)和B,组(1株)。组内色谱图完全相同。B_1组图谱更接近于标准株。裂解图谱与血清型和抗药谱之间未发现有规律性的联系,但它们为伤寒沙门氏菌的鉴定和色谱图库的建立提供了有益的参考。
The chromatograms of pyrolysis gas chromatography (PGC) of fifteen strains of Salmonella typhi were reported to see if there is any possible relation of the graphs to serological typing and drug-resistance spectra of the bact. In the fifteen strains there were fourteen clinical strains and one reference strain (Hg01). The results indicated that the clinical strains might be divided into group A and B (7 strains each) by PGC. The graphs drawn from group A organisms were entirely the same in shape while those of group B showed only basic similarity. According to the diversity of graphs of group B organisms, the group B organisms, may be subdivided into group B1 (4 strains), B2 (2 strains) and B3 (1 strain). The graphs within each subgroup were completely the same and those of subgroup B1 exhibited close similarity to that of the reference strain. Albeit no regular connection of chromatograms with serological types and drug-resistance could be seen, the graphs yet provided useful reference for founding a bank of chromatograms, compaed with which salmonella typhi graph could then be identified.
