Lord Greaves – 2016 Parliamentary Question to the Department for Environment, Food and Rural Affairs
The below Parliamentary question was asked by Lord Greaves on 2016-03-16.
To ask Her Majesty’s Government what assessment they have made of the implications of the discovery in the UK of the tick-borne canine parasite Babesia canis and the associated disease babesiosis in dogs; what action they are taking to provide information to dog owners, breeders, vets and others who come into contact with dogs, including those who deal with stray dogs; and what assessment they have made of the possible introduction into the UK of species of Babesia that may also infect humans, and of the possible presence of, and risks presented by, ticks that can host and spread both Babesia and Borrelia pathogens.
Lord Gardiner of Kimble
Experts at the Animal & Plant Health Agency (APHA) and Public Health England (PHE) are working together to investigate the locally acquired cases in Essex and this will include providing advice to the local authority, vets, pet owners and the public on what to do in the event of finding ticks on animals or observe clinical signs in pet dogs, through specialist press and public messages from the Defra, APHA and PHE communications teams.
On the risks of introduction of pathogens such as Babesia and Borrelia to humans and potential spread by ticks, PHE is responsible for the monitoring of Lyme disease through surveillance of reference laboratory diagnosed cases and provides guidance on avoiding tick bites. PHE runs a “Tick Surveillance Scheme” for ticks found by members of the public, general practitioners, vets and those working with wildlife, so PHE can map tick species across the UK and monitor changes in distribution.
Humans can be infected by Babesia microti, a rodent pathogen, and by Babesia bovis and Babesia divergens. Very few human cases have been reported in Europe or the UK, but virtually all have been related to B. divergens. In the US, human cases are caused by B. microti linked to white footed mice, a common rodent host of Borrelia burgdorferi in N. America. There are no reports of human infection with B. canis.
