Hard Ticks - Overseas

Many of the hard tick species that infect animals in the UK are also present in other parts of Europe and the rest of the world information on these can be found here. There are many tick species that are important both in the effects of their ectoparasitism but also in their ability to transmit other infectious agents.

Ixodes spp.

Rhipicephalus spp.

• Warmer climates
• Causes paralysis in livestock
• Vectors for diseases such as
  • Theileria parva which causes East Coast Fever
  • Babesia bigemina which affects ruminants, mainly in Africa
  • Babesia canis and Ehrlichia canis which affects dogs in warmer climates worldwide

Boophilus spp. These species are important due to their ability to transmit Babesia spp and Anaplasma marginale in cattle. They exist in tropical and subtropical climates and so are predominately found in Asia, Africa, central America and northern Australia.

Amblyomma spp.

• Warmer climates
• Transmits Cowdria ruminatium (heartwater) in Africa
• Transmits 'Q fever' and 'Rocky Mountain spotted fever' in southern USA

Hyalomma spp.

• Warmer climates
• Old World
• Parasites a wide range of both domestic and wild animals
• Involved in the spread of Theileria and Babesia spp.
  • E.g. H. aegyptium is a parasite of tortoises in North Africa which has been spread around the world by the pet trade
