In June 2000, suspected cases of Brazilian spotted fever (BSF) occurred in Coronel Fabriciano Municipality, Minas Gerais State, Brazil. Pooled fleas collected near two fatal cases contained rickettsial DNA. The nucleotide sequence alignment of the 391-bp segment of the 17-kDa protein gene showed that the products were identical to each other and to the R. felis 17-kDa gene, confirming circulation of R. felis in Brazil.
2000年6月，巴西米纳斯吉拉斯州法布里西阿诺镇出现了巴西斑点热（BSF）疑似病例。在两例死亡病例附近采集的混合跳蚤样本中含有立克次氏体DNA。对17-kDa蛋白基因391-bp片段的核苷酸序列比对显示，这些产物彼此相同，且与猫立克次氏体17-kDa基因相同，证实了猫立克次氏体在巴西的传播。
