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

Publication date: Available online 15 December 2017 Source:Ticks and Tick-borne Diseases Author(s): Artem Rogovskyy, Maliha Batool, David C. Gillis, Patricia J. Holman, Igor V. Nebogatkin, Yuliya V. 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...

Publication date: February 2019Source: Current Opinion in Virology, Volume 34Author(s): Lin-Fa Wang, Danielle E AndersonIn the last two decades, several high impact zoonotic disease outbreaks have been linked to bat-borne viruses. These include SARS coronavirus, Hendra virus and Nipah virus. In addition, it has been suspected that ebolaviruses and MERS coronavirus are also linked to bats. It is being increasingly accepted that bats are potential reservoirs of a large number of known and unknown viruses, many of which could spillover into animal and human populations. However, our knowledge into basic bat biology and immuno...

An easy accessibility of molecular methods and the growing amount of sequencing data led to the description of intraspecific variability in 18S rDNA sequences designated as ...

ConclusionThe new I-ELISA based on whole cell Brucella abortus S99 showed a good performance for the detection of Brucella spp. Lack of agreement between the new and the Vircell kit suggest that the performance of ELISA kits might be dependent on the geographical area under study. Hence, validation of the new and the Vircell kits is recommended prior to their implementation in other geographical areas.

Obtained data were statistically analyzed. The overall prevalence of intestinal parasite infections was 33.3%. In lymphoma dogs, the prevalence of protozoa infections (46.7%) was significantly higher (p

DumitracheAbstractMany canine diseases, infectious or parasitic, have been newly reported as autochthonous in the last few years in Eastern Europe. This is notably evident for vector-borne diseases. The mechanisms behind the particular epidemiological pattern of infectious and parasitic diseases of pets in Eastern Europe are complex. Most countries from Eastern Europe are regarded as non-endemic for leishmaniosis, with sporadic cases only in both humans and dogs. However, recently, n...

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. Most...
