Tick Borne Disease
Reducing the Threat of Tick Borne Diseases
University of Glasgow's Small Animal Hospital has talked about the increased geographical spread of ticks, the emergence of new tick borne diseases and the importance of tick bite prevention.
Ticks have never seen so much attention in the Veterinary and consumer media, but what is behind the media noise and how should we be reacting.
Specifically in the UK increasing reported cases of tick borne diseases (TBD) have driven the media agenda but also in the Veterinary profession reports of expansion of the distribution of ticks already endogenous to the UK have also been frequent. As a result, more than ever before, we are reminded of the importance of parasite prevention, particularly tick prophylaxis, to reduce the threat of TBD.
Tick prevalence on the increase;
We are seeing an expansion of the distribution of ticks already endogenous to the UK, with a predominant emphasis on the West and South coasts of England. The geographical expansion of tick species and subsequent TBD is likely to be multifactorial and factors causing this may include;

1) Increasing transportation of pets (for sport, leisure activities or simply taking pets on holiday)

2) Climate change, which may increase the density of vectors in an area or cause them to drift northwards.

3) Increasing urban sprawl with increased proportions of wildlife reservoirs having a closer association with human and pet activity (for example the expansions of urban fox populations) and changes in farming practices (banning of certain sheep dips for example)

4) increasing populations of natural hosts (for example wild deer)

5) The move in 2012 to encourage harmonisation within the EU regarding pet travel rules. This removed the need for compulsory tick treatment for travelling pets returning to the uk.

Tick-Borne Disease: Emergence of New Threats:

Some species if tick,  such as Ixodes ricinus (Ixodes ricinus, the castor bean tick, is a chiefly European species of hard-bodied tick. It may reach a length of 11 mm (0.43 in) when engorged with a blood meal, and can transmit both bacterial and viral pathogens such as the causative agents of Lyme disease and tick-borne encephalitis.)
 The Vector for Lyme disease and the tick Dermacentor reticulatus (D. reticulatus is a vector of various diseases, including Babesia canis, Francisella tularensis, Coxiella burnetti, Theileria equi and several Rickettsia species, such as Rickettsia slovaca.

The vector for Canine Babesiosis and the tick Rhipicephalus sanguineus (The brown dog tick (Rhipicephalus sanguineus), commonly called kennel tick, or pan-tropical dog tick, is a species of tick which is found worldwide, but more commonly in warmer climates. This species is unusual among ticks in that its entire life cycle can be completed indoors)

Rhipicephalus  sanguineus is a vector of the diseases in dogs: canine ehrlichiosis (Ehrlichia canis) and canine babesiosis (Babesia canis). In dogs, symptoms of canine ehrlichiosis include lameness and fever; those for babesiosis include fever, anorexia and anemia

Public health England has reported two cases of infestations with this Brown Dog Tick in residential properties in the UK (Leicestershire and Essex). In these cases the ticks were originally thought to have been introduced into the households by dogs imported from Mediterranean Europe, however infestations became established and were able to survive the winter.

The Dermacentor was found in Essex, (infecting 2 dogs with no travel history yet taken from the dog's skin), also in West Wales, Devon and a fatal case in Kent. Previously it was thought that ticks needed to attach for more than 48 hours to transmit diseases, however, reports now suggest that this might not be the case. Ticks carrying Ehrlichia canis have been shown to infect dogs in as little as 3 hours after attachment, therefore remove ticks as soon as they are observed and, if possible, within 24 hours.

It is ideal to use precautions to avoid the tick from biting the animal in the first instance. During feeding ticks inject a small amount of saliva into the skin and pets become sensitised and allergic to this resulting in stress and, possibly, other dermatological conditions. 
Historically we have been educated about a particular tick season, around March to November and increasing the Summer months, but now tick infestations are lasting all year round due to milder weather and especially the Deer tick which is active year round.
