Abstract
There is a small but distinct difference in DNA base composition between the typhus and spotted fever groups of rickettsiae. The molar percentages of guanine plus cytosine for Rickettsia prowazeki, R. typhi, and R. canada are approximately 30, for R. rickettsi, R. conori, and R. akari they are about 32.5. The percentage for trench fever rickettsia, Rochalimaea quintana, is 38.6.
摘要
斑疹伤寒群立克次体和斑点热群立克次体在DNA碱基组成上存在细微但明显的差异。普氏立克次体、伤寒立克次体和加拿大立克次体中鸟嘌呤加胞嘧啶的摩尔百分比约为30%，而立氏立克次体、康氏立克次体和小蛛立克次体的这一比例约为32.5%。战壕热立克次体（五日热罗卡利马体）的这一比例为38.6%。
