“…Rickettsia monacensis was detected in I. ricinus ticks in Spain, Portugal, Italy (including Sardinia), Turkey, Switzerland, Luxembourg, Germany (including Greifswalder Oie Island), Sweden, Slovakia, Albania, Hungary, Bulgaria, Moldova, Ukraine, Serbia, northwestern Russia (Kaliningrad), Belarus, and Poland (208,280,283,289,(297)(298)(299)(300)(301). The prevalence of R. monacensis in ticks varied between 1% in Germany, 15% in Serbia, 35% Turkey, and 57% in Italy (299,302).…”

SUMMARY Tick-borne rickettsioses are caused by obligate intracellular bacteria belonging to the spotted fever group of the genus Rickettsia . These zoonoses are among the oldest known vector-borne diseases. However, in the past 25 years, the scope and importance of the recognized tick-associated rickettsial pathogens have increased dramatically, making this complex of diseases an ideal paradigm for the understanding of emerging and reemerging infections. Several species of tick-borne rickettsiae that were considered nonpathogenic for decades are now associated with human infections, and novel Rickettsia species of undetermined pathogenicity continue to be detected in or isolated from ticks around the world. This remarkable expansion of information has been driven largely by the use of molecular techniques that have facilitated the identification of novel and previously recognized rickettsiae in ticks. New approaches, such as swabbing of eschars to obtain material to be tested by PCR, have emerged in recent years and have played a role in describing emerging tick-borne rickettsioses. Here, we present the current knowledge on tick-borne rickettsiae and rickettsioses using a geographic approach toward the epidemiology of these diseases.

“…In 2005, R. monacensis was identified as a human pathogen in two patients in Spain (June and September) and in one patient in Sardinia, Italy (April), by using molecular tools (297,298). A rickettsial strain was isolated from blood samples of Spanish patients by shell vial culture (298).…”

“…This tick species was first isolated in 2002 in Germany, 18 and later in other European countries. [31][32][33] It is one of the most prevalent species in Europe, especially in relatively humid regions, and is the main vector of R. monacensis.…”

Background: Ticks serve as vectors and reservoirs for a variety of bacterial, viral and protozoan pathogens affecting humans and animals. Unusual increased tick aggressiveness was observed in 2008-2009 in northeastern Greece. The aim of the study was to check ticks removed from persons during 2009 for infection with Rickettsia species.Methods: A total of 159 ticks were removed from 147 persons who sought medical advice in a hospital. Tick identification was performed morphologically using taxonomic keys. DNA was extracted from each individual tick and a PCR assay targeting the rickettsial outer membrane protein A gene of Rickettsia spp. was applied.Results: Most of the adult ticks (132/153, 86.3%) were Rhipicephalus sanguineus. Rickettsiae were detected in 23 of the 153 (15.0%) adult ticks. Five Rickettsiae species were identified: R. aeschlimannii, R. africae (n=6), R. massilae (4), R. monacensis (1), and Candidatus R. barbariae (1). To our knowledge, this is the first report of R. africae, R. monacensis, and Candidatus R. barbariae in Greece.Conclusions: Several Rickettsia species were identified in ticks removed from humans in Greece, including those that are prevalent in northern and southern latitudes.

“…Diese bislang ausschließlich in Dermacentorarten vorkommenden Rickettsienarten könnten mit der räumlichen Ausbreitung von D. reticulatus [32] und möglicherwei-se auch D. marginatus an Bedeutung gewinnen. Die ebenfalls in Deutschland nachgewiesene Rickettsienart R. monacensis wurde als möglicher Auslöser einer dem Mittelmeerfleckfieber ähnlichen Erkrankung beschrieben [33].…”
