Detection of Borrelia lusitaniae, Rickettsia sp. IRS3, Rickettsia monacensis, and Anaplasma phagocytophilum in Ixodes ricinus collected in Madeira Island, Portugal.
A total of 300 Ixodes ricinus ticks were tested by polymerase chain reaction (PCR) for the presence of Borrelia spp., Rickettsia spp., and Anaplasma phagocytophilum. Sequence analysis demonstrated 8 (2.7%) ticks infected with B. lusitaniae, 60 (20%) with Rickettsia spp., and 1 (0.3%) with A. phagocytophilum. Seven (2.3%) ticks were coinfected with B. lusitaniae and Rickettsia spp., 2 (0.6%) wit...
متن کاملIsolation of rickettsia helvetica from ticks in Slovakia.
UNLABELLED To date, only three rickettsial species have been found in ticks in Slovakia by serological and/or molecular-biological techniques, namely Rickettsia slovaca, Candidatus rickettsia IRS, and Rickettsia raoultii. Recently, we succeeded in isolation of the forth species, Rickettsia helvetica from Ixodes ricinus, the most frequent tick in Slovakia. The isolation, positive for 10% of test...
متن کاملEvidence of Rickettsia helvetica infection in humans, eastern France.
A 37-year-old man living in eastern France seroconverted to Rickettsia helvetica in August 1997, 4 weeks after the onset of an unexplained febrile illness. Results of a serosurvey of forest workers from the area where the patient lived showed a 9.2% seroprevalence against R. helvetica. This organism may pose a threat for populations exposed to Ixodes ricinus ticks.
متن کاملGenetic identification of rickettsiae isolated from ticks in Japan.
Following the description in Japan of Japanese spotted fever, caused by Rickettsia japonica, a search for the vector of this disease led to the isolation of several rickettsiae from various tick species. Sixty-three rickettsial isolates were obtained from six different tick species, and six type strains were described by PCR and monoclonal antibody testing. We identified these six strains by am...
