Fleas collected in Algeria in the district of Oran between July and September 2003 were tested by polymerase chain reaction for the presence of Rickettsia spp. DNA using primers amplifying gltA and OmpA genes. Two gltA sequences identical to those of an emerging pathogen, Rickettsia felis, were detected including i) R. felis California 2 in Ctenocephalides canis from rodents and ii) R. felis RF2125 in Archeopsylla erinacei from hedgehogs.
2003年7月至9月间在阿尔及利亚奥兰地区采集的跳蚤，通过聚合酶链反应，使用扩增gltA和OmpA基因的引物检测是否存在立克次氏体属DNA。检测到两个与一种新出现的病原体——猫立克次氏体的gltA序列相同，包括：i）来自啮齿动物的犬栉首蚤中的猫立克次氏体加利福尼亚2型；ii）来自刺猬的刺猬古蚤中的猫立克次氏体RF2125。
