N2 - Migratory birds are known to play a role in the long-distance transportationof microorganisms. To investigate whether this is true for rickettsial agents, weundertook a study to characterize tick infestation in populations of the migratorypasserine bird Riparia riparia (Passeriformes: Hirundinidae), the sand martin. A totalof 194 birds were sampled and ticks removed from infested birds. The ticks wereidentified as female Ixodes lividus (Acari: Ixodidae) using standard morphologicaland molecular techniques. Tick DNA was assayed to detect Rickettsia spp. usingpolymerase chain reaction and DNA was sequenced for species identification.A single Rickettsia spp. was detected in 100% of the ticks and was designatedRickettsia sp. IXLI1. Partial sequences of 17-kDa and ompA genes showed greatestsimilarity to Rickettsia sp. TCM1, an aetiological agent of Japanese spotted fever-likeillness, previously described in Thailand. Phylogenetic analysis showed that Rickettsiasp. IXLI1 fitted neatly into a group containing strains Rickettsia japonica, Rickettsiasp. strain Davousti and Rickettsia heilongjiangensis. In conclusion, this researchshows that U.K. migratory passerine birds host ticks infected with Rickettsia speciesand contribute to the geographic distribution of spotted fever rickettsial agents.
