These  species are important due to their ability to transmit  ''[[Babesia|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. There  are several important veterinary species, all of which are one host  ticks and are mainly important in cattle though they can be seen in most  ungulates.

The  entire life cycle of this tick is spent on a single host and can be  completed in just 6 weeks. It is an important species as it is a vector  for ''Babesia bigemina'' and ''Babesia bovis'' that are responsible for  texas cattle fever. As well as its ability to transmit ''Anaplasma  marginale'' like many other tropical hard ticks.

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.

Boophilus spp.

Amblyomma spp.

These ticks can be identified by;

  • Large size
  • Ornate scutums
  • Eyes present
  • Festoons
  • Long palps
  • Long legs

These ticks are distributed throughout tropical and sub-tropical areas of Africa as well as in temperate North America. The large mouth parts cause large painful bites and allow the females to ingest large volumes of blood which can lead to anaemia.

Amblyomma americanum

Amblyomma americanum, the lone star tick - CDC, Wikimedia Commons
Also known as: Lone star tick

This tick is found throughout central and eastern USA and is primarily important as a vector but has also been shown to reduce weight gain in cattle. It is responsible for transmission of Rickettsia rickettsii, Francisella tularensis, Q fever and Berrelia burgdorferi

Amblyomma variegatum

Also known as: Bont ticks

variegated or tropical bont tick

Found throughout Africa, this tick is very important in its ability to transmit Cowdria ruminatium (heartwater) in Africa as well as viral Nairobi sheep disease and Q fever. There is distinct variation in the appearance of the males and female, the males are highly ornate with orange markings on the scutum compared to the brown female with a large pale patch on the scutum.

Hyalomma spp.

These are large ticks that are commonly found on the legs, udder, tail or perianal region of mammals. They are either two or three host ticks found in central Asia, southern Europe and North Africa. This is largely dependant Ticks of these species can identified by;

  • Eyes present
  • Long mouthparts
  • Ventral plates around male anus
  • Inornate
  • Banded legs

Hyalomma anatolicum

Also known as: Bont-legged tick

There are two subspecies known, H. anatolicum excavatum that is found in central Europe and Asia and H. anatolicum anatolicum which can be found throughout the rest of the range. These ticks cause tick toxicosis in Africa which is a sweating sickness seen in pigs and ruminants. This is accompanied by a profuse moist eczema and hyperaemia of the mucous membranes. This species can also be involved in the transmission of Theileria, Babesia spp. as well as Anaplasma marginale.

Hyalomma aegyptium

Also known as: Tortoise tick

Infects tortoises in southern Europe and southwest Asia as well as lizards and occasionally dogs and horses. However this tick is being spread around the globe by the increasing pet trade in tortoises.
