In a large-scale survey in the UK, recruited veterinary practices were asked to inspect client-ownedcats and dogs, selected at random between April and June 2018, following a standardised flea inspection protocol. A total of 326 veterinary practices participated and 812 cats and 662 dogs were examined during the 3-month period. Fleas were collected, identified to species level and fleas of the same species collected from a single animal were pooled together and treated as a single sample. A total of 470 pooled flea samples were screened by PCR and DNA sequence analysis for a subset of Rickettsia species including R. felis and R. typhi. On analysis, 27 (5.7%) of the pooled flea samples were positive for R. felis DNA; these were predominantly in the cat flea, Ctenocephalides felis, but one dog flea, Ctenocephalides canis was also positive for this pathogen.

在英国进行的一项大规模调查中，按照标准化的跳蚤检查规程，要求招募的兽医部门对客户拥有的猫狗进行检查，这些猫狗是在2018年4月至6月之间随机选择的。在三个月的时间内，总共参加了326次兽医检查，检查了812只猫和662只狗。收集蚤，鉴定到物种水平，将从单个动物收集的相同物种的蚤汇集在一起​​，并作为单个样品处理。共有470个汇集蚤样品通过PCR和DNA序列分析的子集筛选立克次氏体的物种，包括R.蚤和R.伤寒沙门氏菌。经分析，合并的跳蚤样品中有27株（5.7％）的R. felis呈阳性脱氧核糖核酸; 这些主要在猫跳蚤Ctenocephalides felis中出现，但其中一只狗跳蚤Ctenocephalides canis也对该病原体呈阳性反应。
