Due to the increased trade in exotic reptiles, many of which are infested with ticks of various genera, there is an increased risk of exotic ticks and pathogens being introduced and potentially becoming established in new geographical areas. Despite the number and variety of tick species collected from reptiles, their role in the maintenance of pathogens and transmission to humans has not been fully investigated for all species. The potential public health risks to the United Kingdom have been examined through a preliminary study involving the collection and identification of exotic tick species imported via the reptile trade. Reptiles imported into Heathrow Airport, London (July 2003-October 2004) were carefully examined for ectoparasites. Five species of tick were collected: Aponomma exornatum, Ap. latum, Amblyomma rotundatum, Am. dissimile and Am. nuttalli. This is the first report of Am. dissimile identified from an interception at Heathrow airport. The potential for establishment of exotic ticks in the UK and the public health risks are discussed.
* Researchers collected and analyzed 421 ticks from various migratory songbird species, identifying key microbial communities and several pathogens present in those ticks.
* Findings reveal that specific microbial interactions among ticks could shape pathogen dynamics, highlighting "hotspots" where migrating birds may contribute to the spread of ticks and their associated diseases over long distances.
Background: Ticks are significant vectors of pathogens, including viruses, bacteria, and protozoa. With approximately 900 tick species worldwide, many are expanding their geographical range due to changing socioeconomic and climate factors. The Danube Delta, one of Europe's largest wetlands, is an ecosystem that, despite its ecological importance, remains understudied concerning the risk of introducing new tick-borne viruses.
In Brazil, the wild boar (Sus scrofa) is the main invasive exotic species, responsible for causing various economic, environmental, and health damages to biodiversity. In view of the above, we aimed in our study to investigate the occurrence of endo and ectoparasites in free-ranging wild boars in the northwest region of the state of São Paulo, Brazil. In total, 45 animals of different sexes and ages were examined in this research.
* Researchers developed a novel multi-epitope recombinant protein using five selected antigenic sequences to enhance immune response and stability for potential immunization trials.
* The constructed protein showed promising results in immunized animals, including increased antibody levels and a strong immune response, indicating its potential for large-scale use in preventing tropical theileriosis in cattle worldwide.
The tick Hyalomma marginatum is expanding its geographical range, reinforcing the need for surveillance and control to prevent the emergence of tickborne equine disease. Daniel Armstrong, policy adviser for exotic animal diseases at Defra, explains more.
