Diversity of Borrelia spirochetes and other zoonotic agents in ticks from Kyiv, Ukraine

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 illness. Despite its zoonotic potential, the prevalence of B. miyamotoi in ticks has not been examined in Ukraine. Similarly, data on the prevalence of other important tick-borne pathogens, Anaplasma phagocytophilum, Babesia spp., Bartonella spp., Francisella tularensis, and Rickettsia spp., in ixodid ticks are scarce or even absent. Thus, the overall objective of this study was to investigate the prevalence of these tick-borne pathogens in questing I. ricinus and Dermacentor reticulatus ticks collected in recreational parks of Kyiv, the most densely populated city of Ukraine. A total of 182 adult I. ricinus, 98 nymphal I. ricinus, and 98 adult D. reticulatus ticks were molecularly analyzed for the presence of these pathogens. As a result, the study shows a greater diversity of Borrelia genospecies in questing I. ricinus ticks than previously reported. The most...

HofmeesterAbstractCattle grazing has been suggested to reduce the risk for Lyme borreliosis by decreasing the density of questing Ixodes ricinus infected with Borrelia burgdorferi sensu lato. We tested the hypotheses that cattle grazing used in woodland management decreases the density of questing I. ricinus, and that it decreases the nympal infection prevalence of B. burgdorferi sensu lato. We further expected the nympal infection prevalence of tick-borne pathogens that ...

CONCLUSIONS: This study demonstrates the potential danger from the inadvertent introduction of novel disease pathogens and vectors. Awareness of co-infections and Dermacentor reticulatus-related pathogens needs to be increased. PMID: 31694625 [PubMed - in process]

Smith, Nicole NemethAbstractCervid babesiosis, caused by the protozoan hemoparasite Babesia odocoilei and transmitted by the blacklegged tick Ixodes scapularis, is an emerging disease of Canadian cervids. This pathogen has not yet been described in humans. Data are lacking on the role of migratory birds in the adventitious spread of Ba. odocoilei-infected ticks, as well as on the infection status of I. scapularis in ...

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...

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...

Mepron, a thick liquid antimicrobial drug used to treat Babesia and malaria, as well as a fungal infection called Pneumocystitis carinii. In 2011, the United Kingdom stopped requiring that dogs brought into the country be inspected for ticks. Earlier this year, several dogs tested positive for babesia, a malaria-like disease transmitted to ticks that previously had only been found in foreign. These dogs had never left the U.K. While babesiosis is a new worry to U.K. dog owners, it's been a threat to human beings for years -- it just hasn't become a health-scare-of-the-week like Zika, West Nile, avian and swine flu.
