Detection of Ehrlichia phagocytophila DNA in Ixodes ricinus ticks from areas in Switzerland where tick-borne fever is endemic.

چکیده
A total of 1,523 adult Ixodes ricinus ticks were collected from regions where bovine ehrlichiosis is endemic and were examined for Ehrlichia phagocytophila via PCR. Of the ticks from cattle with ehrlichiosis, the ticks from healthy cattle, and the free-living ticks, 26.5% (18 of 68), 4.4% (35 of 802), and 0.8% (5 of 653), respectively, were positive.

High prevalence of granulocytic Ehrlichiae and Borrelia burgdorferi sensu lato in Ixodes ricinus ticks from Bulgaria.
Bulgarian Ixodes ricinus ticks were examined for Ehrlichia and Borrelia coinfection: 34 and 32% of adult ticks and at least 2 and 10% of nymphs were positive for these infections, respectively. Coinfections and dual or triple Borrelia infections were frequent, although Ehrlichia phagocytophila heterogeneity was minimal. Multiple tick-borne bacteria coexist in I. ricinus ticks in southeastern Eu...
متن کاملQuantitative real-time PCR for detection of members of the Ehrlichia phagocytophila genogroup in host animals and Ixodes ricinus ticks.
A TaqMan PCR was established for identification and quantitation of members of the Ehrlichia phagocytophila group in experimentally infected cows and in Ixodes ricinus ticks. The TaqMan PCR identified a 106-bp section of the 16S rRNA gene by use of a specific fluorogenic probe and two primers. This technique was specific for members of the E. phagocytophila group, which include E. phagocytophil...

Human ehrlichiosis is a newly recognized rickettsial disease, first described in 1986 (5) in the United States. The first European case of ehrlichiosis, diagnosed on a serological and clinical basis, was reported in Portugal in 1991 (7). Furthermore, serological surveys recently conducted in Switzerland and the United Kingdom have shown the presence of antibodies to Ehrlichia phagocytophila in ...
متن کاملPersistence of Ehrlichia phagocytophila Infection in Two Age Groups of Lambs
Tick-borne fever (TBF) is caused by the rickettsiae Ehrlichia phagocytophila and is a common disease in sheep in tick (Ixodes ricinus) infested areas in Norway. Earlier investigations have shown that some sheep could remain infected for several months after the primary infection. In this study, the persistence of E. phagocytophila after experimental infection was investigated in 2 age groups of...
متن کاملPrevalence of granulocytic Ehrlichiae in Ixodes ricinus ticks in Middle Germany (Thuringia) detected by PCR and sequencing of a 16S ribosomal DNA fragment.
A total of 305 Ixodes ricinus ticks (243 nymphs and 62 adults) were collected from three different regions of Thuringia in Middle Germany which are known to be endemic for Borrelia burgdorferi. Our aim was to investigate the carrier rate of ticks for granulocytic Ehrlichia species. The presence of ehrlichial 16S ribosomal DNA was investigated by polymerase chain reaction. Using primers specific...
