Tick infestations of wildlife and companion animals in Ontario, Canada, with detection of human pathogens in Ixodes scapularis ticks

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 stricto (s.s.). Amblyomma americanum ticks were tested for Ehrlichia chaffeensis. A total of 1,687 ticks of six species were collected from 334 animals, including 224 raccoons (n = 1,381 ticks) and 50 dogs (n = 67 ticks). The most common tick species collected from parasitized raccoons were Ixodes texanus (n = 666 ticks) and Dermacentor variabilis (n = 600 ticks), which were removed from 58.5% (median: 2 ticks; range: 1-36) and 49.1% (median: 2 ticks; range: 1-64) of raccoons, respectively. Of I. scapularis tested, 9.3% (4/43) were positive for B. burgdorferi s.s. and 2.3% (1/43) for A. phagocytophilum. These results reveal that numerous tick species parasitize common, peridomestic wildlife and that at least two zoonotic, tick-borne pathogens circulate in southern Ontario. Host-tick vector-pathogen dynamics should continue to be monitored in the ...

CONCLUSION: Hospital characteristics and case mix do not account for the significant variation in CDRs across U.S. hospitals. Individual hospitals are in themselves independent risk factors for Caesarean delivery. Choosing to give birth in a certain hospital may put women at an increased risk of having a Caesarean delivery, without maternal or neonatal benefit.

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 ...

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...
