“…R. hoogstraalii has been originally detected in H. sulcata from sheep and goats in Croatia, and it is closely related to Rickettsia felis [12]. Duh et al [13] showed that it causes a cytopathic effect in Vero cells and different arthropod cell lines, but its pathogenicity in vertebrate hosts is unknown. Other reports from Europe refer to infection in Haemaphysalis spp.…”

“…Our gltA sequences, from both I. ricinus and H. sulcata (GenBank Accession No. KY418024, KY418025), showed 100% similarity to the Rickettsia endosymbiont of H. punctata isolate Hae69 from Spain (EU303311) and 99% to the endosymbiont of H. sulcata from Croatia (DQ081187); these endosymbionts have been subsequently classified as R. hoogstraalii by Duh et al [13].

During the investigations on ticks and tick-borne pathogens (TBP) range expansion in the Northern Apennines, we captured 107 Podarcis muralis lizards. Sixtyeight animals were infested by immature Ixodes ricinus, Haemaphysalis sulcata and H. punctata. Borrelia burgdorferi s.l. was detected in 3.7% of I. ricinus larvae and 8.0% of nymphs. Together with the species-specific B. lusitaniae, we identified B. garinii, B. afzelii and B. valaisiana. Rickettsia spp. (18.1% larvae, 12.0% nymphs), namely R. monacensis, R. helvetica and R. hoogstraalii, were also found in I. ricinus. R. hoogstraalii was detected in H. sulcata nymphs as well, while the two H. punctata did not harbour any bacteria. One out of 16 lizard tail tissues was positive to R. helvetica. Our results support the hypothesis that lizards are involved in the epidemiological cycles of TBP. The heterogeneity of B. burgdorferi genospecies mirrors previous findings in questing ticks in the area, and their finding in attached I. ricinus larvae suggests that lizards may contribute to the maintenance of different genospecies. The rickettsiae are new findings in the study area, and R. helvetica infection in a tail tissue indicates a systemic infection. R. hoogstraalii is reported for the first time in I. ricinus ticks. Lizards seem to favour the bacterial exchange among different tick species, with possible public health consequences.

“…In addition, the existence of another novel SFG rickettsiae was demonstrated in Haemaphysalis sulcata ticks collected from sheep and goats in Croatia. This new rickettsia was named R. hoogstraali, and was isolated and deposited in two different collections (Duh et al, 2009). A rickettsial genotype from the R. massiliae genogroup called Candidatus Rickettsia kulagini was identified in Rh.…”

Update on tick-borne bacterial diseases in Europe

Summary :In recent years, the prevalence of tick-borne bacterial diseases has significantly increased in European countries. The emergence and reemergence of these illnesses are attributed to changes in the environment and human behavior. Several diseases are caused by bacteria initially isolated from ticks and subsequently considered pathogenic. It is necessary to consider the bacteria found in arthropods capable of biting humans as potential human pathogens. Here we review the clinical and epidemiological data on bacterial tick-borne diseases in European countries. We focus on the epidemiological and clinical aspects of tick-borne rickettsioses and give an overview of other tick-borne illnesses as well as the emergence and re-emergence of these diseases.

“…Currently, 26 Rickettsia species with validated and published names have been reported (http://www.bacterio.cict.fr/qr /rickettsia.html), including Rickettsia asiatica (3), Rickettsia heilongjiangensis (4), Rickettsia hoogstraalii (5), Rickettsia raoultii (6), and Rickettsia tamurae (7), which were reported since 2005 (2). In addition to these 26 species, subspecies have been proposed within the Rickettsia conorii (8) and Rickettsia sibirica (9) species.…”

In addition, R. hoogstraalii was detected in 30% of the Haemaphysalis punctata ticks collected in Cyprus (258) and in 3% of H. punctata and 16% of H. sulcata ticks from Spain (319).…”

Update on Tick-Borne Rickettsioses around the World: a Geographic Approach

et al. 2013

View full text Add to dashboard Cite

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.
