Transmission of Rickettsia massiliae in the tick, Rhipicephalus turanicus.

摘要: Rickettsia massiliae, strain Bar29, was detected in engorged female ticks of the Rhiphicephalus sanguineus group collected Corsica, a French Mediterranean island. Ticks were identified by molecular analysis as Rhipicephalus turanicus (Pomerantsev) (Acari: Ixodidae). Twenty larvae second generation obtained from R. massiliae-infected, tested polymerase chain reaction (PCR) and all positive for massiliae. Larvae same cohort fed on rabbits specimens subsequent stages third PCR. Both transovarial transstadial transmission demonstrated; rate estimated at 100%. A high filial infection 132 out 134 five infected females fourth infected. When saliva samples half-engorged Rh. PCR, four positive. massiliae faeces PCR immunofluorescence assay, although no rickettsiae could be maintained culture. Co-feeding/transsexual Bar29 demonstrated feeding male rabbit with (Latreille) Ixodidae) (the latter only uninfected available). Infection subsequently nine thirteen (69.2%). These results suggest that are potential vectors reservoirs Bar29.
