Global Tick Risk Update
New Studies Map Tick Risks and Vet Warnings Across Multiple Regions
Anonymous
Recent research and veterinary guidance highlight the varied risks posed by ticks. In Thailand, researchers found that the bacterial communities inside brown dog ticks differ markedly by location, underscoring how local environments may shape their microbiomes. In Great Britain, researchers used legally required records of the sole licensed bovine babesiosis treatment to map clinically recognized cases across the country, offering a detailed view of the tick-borne cattle disease despite limited routine surveillance. In Australia’s Logan region, veterinarians are warning pet owners as paralysis-tick cases rise, urging preventive treatment and prompt veterinary care if a tick is found because pets can worsen for up to 48 hours after removal.
Key Points
1
The Thailand study analyzed 131 brown dog ticks collected from dogs in five provinces, using Oxford Nanopore sequencing of the full-length bacterial 16S rRNA gene rather than conventional short-read sequencing.
2
The British babesiosis researchers used treatment notifications from 2016 to 2024 to map clinically recognized cases onto two-kilometre grid squares across Great Britain; the disease is caused by Babesia parasites, with the sheep tick Ixodes ricinus the principal vector in the British Isles.
3
Park Ridge Animal Hospital reported treating seven tick-paralysis patients in one day. Veterinarian Nigel Thomas said cases typically surge from late August through Christmas, although ticks can affect pets year-round.
4
Signs of tick paralysis can include a change in an animal’s bark or meow, difficulty standing and breathing problems; the Logan veterinarian advised treating any change from a pet’s normal behavior seriously during tick season.
