“…20 The latest case was diagnosed in Spain by retrospective PCR testing of eschar tissue from a female patient from Buenos Aires, Argentina. 21 There may have been additional cases of human infection with R. massiliae . Children diagnosed with Mediterranean spotted fever in Catalonia, an area that is endemic for the Bar29 isolate of R. massiliae , were refractory to treatment with rifampin, tested as an alternative antibiotic when tetracycline is contraindicated.…”

Abstract. A recurrent focus of Rhipicephalus sanguineus infestation was investigated in a suburban area of southern California after reports of suspected Rocky Mountain spotted fever in two dogs on the same property. Abundant quantities of Rh. sanguineus were collected on the property and repeatedly from each dog, and Rickettsia massiliae DNA was detected by polymerase chain reaction (PCR). Whole blood and serum samples from four dogs were tested by using PCR and microimmunofluorescent assay for antibodies against spotted fever group rickettsiae. Serum samples from all four dogs contained antibodies reactive with R. massiliae , R. rhipicephali , R. rickettsii , and 364D Rickettsia but no rickettsial DNA was detected by PCR of blood samples. Serum cross-absorption and Western blot assays implicated R. massiliae as the most likely spotted fever group rickettsiae responsible for seropositivity. To our knowledge, this is the first detection of R. massiliae in ticks in California.

“…23,28,[35][36][37] Rickettsia massiliae has been detected in Rhipicephalus ticks in Europe, Africa, and in South and North America. [37][38][39] There are several confirmed clinical cases caused by R. massiliae reported in the peer-reviewed literature. [37][38][39] Furthermore, it is believed that R. massiliae is responsible for cases of SFG rickettsioses resistant to rifampin in Catalonia, Spain, 39 which corresponds closely to the observation that R. massiliae is naturally resistant to this antibiotic.…”

Abstract. We report molecular evidence for the presence of spotted fever group rickettsiae (SFGR) in ticks collected from roe deer, addax, red foxes, and wild boars in Israel. Rickettsia aeschlimannii was detected in Hyalomma marginatum and Hyalomma detritum while Rickettsia massiliae was present in Rhipicephalus turanicus ticks. Furthermore, a novel uncultured SFGR was detected in Haemaphysalis adleri and Haemaphysalis parva ticks from golden jackals. The pathogenicity of the novel SFGR for humans is unknown; however, the presence of multiple SFGR agents should be considered when serological surveillance data from Israel are interpreted because of significant antigenic cross-reactivity among Rickettsia . The epidemiology and ecology of SFGR in Israel appear to be more complicated than was previously believed.
