Babesia canis

• Dogs
  • Complex epidemiology
  • Recognised species are extending their endemic ranges due to the discovery of the small Babesia species, pet passport scheme and increased overseas travel
  • Large species comprises 3 subspecies
    • B. canis canis is the most important
      • Dermacentor vector
      • Largely confined to southern Europe but is spreading
    • B. canis uses Rhipicephalus as a vector and is spreading northwards through Europe
    • B. gibsoni is now established in the USA and South-East Asia
  • British dogs have no immunity as no species are endemic to the UK so are highly susceptible if taken abroad
  • Prevention of tick bites by use of an 'Amitraz' collar is currently the best method of protection
