已建立了一个包含72株鼠伤寒沙门氏菌复合克隆的参考菌株集合，这些菌株是从不同地理位置的各种宿主和环境来源中分离得到的，用于研究自然种群的变异。其中包括血清型为鼠伤寒沙门氏菌、圣保罗沙门氏菌、海德堡沙门氏菌、副伤寒B沙门氏菌（包括爪哇变种）和慕尼黑沙门氏菌的菌株。这些菌株通过酶电泳对24个染色体结构基因的等位基因变异进行了特征分析，代表了48种独特的多位点基因型（电泳型或ETs），体现了鼠伤寒沙门氏菌复合群基因型变异的全部范围。通过邻接法从Nei氏标准遗传距离矩阵生成的系统发育树显示了ETs之间的进化遗传关系。
A collection of 72 reference strains of the Salmonella typhimurium complex of clones recovered from a variety of hosts and environmental sources in diverse geographic locations has been established for use in studies of variation in natural populations. Included are strains of the serovars S. tyhimurium, S. saintpaul, S.heidelberg, S. paratyphi B (including variety java) and S. muenchen. The strains, which have been characterized by enzyme electrophoresis for allelic variation in 24 chromosomal structural genes and represent 48 distinctive multilocus genotypes (electrophoretic types or ETs), exemplify the full range of genotypic variation in the S. typhimurium complex. Evolutionary genetic relationships among the ETs are indicated in a phylogenetic tree generated by the neighbour-joining method from a matrix of Nei's standard genetic distance.
