IJERPH, Vol. 15, Pages 994: Seasonal Patterns in the Prevalence and Diversity of Tick-Borne Borrelia burgdorferi Sensu Lato, Anaplasma phagocytophilum and Rickettsia spp. in an Urban Temperate Forest in South Western Slovakia International Journal of Environmental Research and Public Health doi: 10.3390/ijerph15050994 Authors: Michal Chvostáč Eva Špitalská Radovan Václav Tatiana Vaculová Lenka Minichová Markéta Derdáková In Europe, Ixodes ricinus is the most important vector of tick-borne zoonotic bacteria. It transmits spirochaetes from the Borrelia burgdorferi sensu lato complex, Anaplasma phagocytophilum and Rickettsia spp. Although spatial differences in the prevalence of tick-borne pathogens have been intensively studied, seasonal (within-year) fluctuations in the prevalence of these pathogens within sites are often overlooked. We analyzed the occurrence and seasonal dynamics of Ixodes ricinus in an urban forest in Bratislava, Slovakia. Furthemore, we examined temporal trends in the community structure of B. burgdorferi s.l., A. phagocytophilum and Rickettsia spp. in questing and bird-feeding ticks. The total prevalence for B. burgdorferi s.l. in questing I. ricinus was 6.8%, involving six genospecies with the dominance of bird-associated B. garinii and B. valaisiana. A. phagocytophilum, R. helvetica and R. monacensis occurred in 5.9%, 5.0% and 0.2% of questing ticks, respectively. In total...

Booth, Kathleen DePonte, Ming-Ji Wu, Xianping Liang, Subhasis Mohanty, Fred Kantor, Erol FikrigAbstractIxodes scapularis vectors several pathogens including Borrelia burgdorferi, the agent of Lyme disease. Nymphal and larval stages, and the pathogens transmitted by I. scapularis are maintained in a zoonotic cycle involving rodent reservoir hosts, predominantly Peromyscus leucopus. Humans are not reservoir hosts, however, accidental encounters of infected ticks with humans, results in pathogen tran...

The objectives of this study were to investigate the geographic distribution and magnitude of tick infestations in opportunistically sampled mammalian wildlife and companion animals (i.e., dogs) in southern Ontario and to test these ticks for evidence of zoonotic tick-borne pathogens. Ticks collected from wildlife carcasses, live-trapped wildlife and companion animals (2015-2016), as well as wildlife diagnostic cases (2011-2013), were identified to species and life stage. Ixodes scapularis ticks were tested by real-time PCR for Anaplasma phagocytophilum, Babesia microti, Borrelia miyamotoi and Borrelia burgdorferi sensu st...

In this study, bird species migrating through Bulgaria were investigated as carriers of zoonotic pathogens. In total, 706 birds belonging to 46 species were checked for the presence of various bacterial pathogens (Campylobacter, Yersin ia, Salmonella, Listeria, Escherichia coli, Staphylococcus aureus, Francisella tularensis, Coxiella burnetii, Borrelia burgdorferi, and Brucella spp.). From 673 birds we investigated fecal samples, from the remaining 33, blood samples. We detected Campylobacter 16S rDNA gene in 1.3% of birds, but no ne were of pathogenic Campylobacter jejuni and Campylobacter coli species. Escherichia coli 1...

Lyme disease is the most frequently reported zoonotic tick-borne disease worldwide, and the number of infected humans is increasing. Lyme disease (or Lyme borreliosis) is an affection caused by the spirochete Borrelia burgdorferi, sensu lato. Lyme disease is also reported as a variety of misleading clinical symptomatologies. Infected patient ’s blood serology is the most currently test used for its diagnosis. However, serology has a low sensitivity, which ranges from 34 % to 70%.Thus, there are numerous subsequent false-negative diagnoses despite an active clinical infection profile.

We present case studies on the role of rodents in the cycles of Bartonella spp., of wild ungulates in the cycle of Babesia spp., and of various wildlife species in the life cycle of Leishmania infantum, Anaplasma phagocytophilum and Rickettsia spp. These examples highlight the usefulness of surveillance strategies focused on neglected zoonotic agents in wildlife as a source of valuable information for health professionals, nature managers and (local) decision-makers. These benefits could be further enhanced by increased collaboration between researchers and stakeholders across Europe and a more harmonised and coordinated a...

Rogovska, Maksym S. Rogovskyy Lyme borreliosis (LB) is caused by tick-borne spirochetes of the Borrelia burgdorferi sensu lato complex. LB is the most prevalent vector-borne illness in Ukraine, but current data on the prevalence of LB pathogens in their tick vector, Ixodes ricinus, are lacking. I. ricinus ticks may also carry Borrelia miyamotoi, an emerging relapsing fever group spirochete that has been implicated in human ill...

In this study, we evaluated two mouse models - the C3H/N and Balb/c strains for susceptibility to infection and ability to transmit the pathogens via tick vector and to reveal the potential interactions between various bacterial tick-borne agents. Our results indicated that the C3H/N and Balb/c mice are well-accepted models of B. afzelii infection. However, they are not suitable for interaction studies with R. helvetica since the animals did not acquire rickettsiemia and do not transmit Rickettsia sp. to feeding ticks.

Conclusions: The results of detection and attribution studies can inform evidence-based risk management to reduce current, and plan for future, changes in health risks associated with climate change. Gaining a better understanding of the size, timing, and distribution of the climate change burden of disease and injury requires reliable long-term data sets, more knowledge about the factors that confound and modify the effects of climate on health, and refinement of analytic techniques for detection and attribution. At the same time, significant advances are possible in the absence of complete data and statistical certainty:...

Conclusion: Our results highlight the potential for climate change to have an effect on future Lyme disease risk in Canada even if the Paris Agreement’s goal to keep global warming below 2°C is achieved, although mitigation reducing emissions from RCP8.5 levels to those of RCP6.0 or less would be expected to slow tick invasion after the 2030s. https://doi.org/10.1289/EHP57 Received: 02 March 2016 Revised: 26 August 2016 Accepted: 30 August 2016 Published: 31 May 2017 Address correspondence to H.
