It´s a disease caused by a protozoan parasite Trypanosoma equiperdum, it´s sexually transmitted during natural mating or by artificial insemination with infected semen. It appears to disappear from the genital tract periodically and the horse may become non-infectious for weeks to months. Mucous membrane transmission via the conjunctiva of the eyes may occur.

There are five equine herpesvirus that are found in the horse environment and are associated with a variety of equine disease syndromes. EHV-1 causes respiratory disease, the horse shows variable signs which include elevated temperature, nasal discharge, enlarged glands under the jaw and coughing.

Infectious disease caused by a Lentivirus and transmitted by biting insects that transfer blood from an infected horse to an uninfected horse. It´s characterised by recurrent episodes of fever, anaemia, thrombocytopenia, loss of appetite, depression, rapid loss of weight, oedema of the lower parts of the body, incoordination and abortions.

It´s a highly infectious viral respiratory disease characterised by fever and dry coughing, mostly affecting non-vaccinated horses. It´s transmitted from horse to horse in close proximity by coughing and inhaling aerosolised live virus and also from horses to people to horses via hands, clothes, grooming equipment or tack contaminated with infectious material. 

It´s a highly contagious disease of varying severity that can cause occasionally abortion or even death in horses. The signs of EVA are very variable. Common symptoms include fever, depression, loss of appetite, swelling, stiffness of the limbs and conjunctivitis.

It´s a life threatening infectious disease caused by the bacterium Burkholderia mallei. The organism is spread, most commonly by the ingestion of contaminated food or water.

It´s an important cause of life threatening anaemia in horses. Biting ticks spread the protozoan parasitic infection of the red blood cells from horse to horse. It´s caused by the protozoan parasites Babesia caballi and Theileria equi, which invade the horse's red blood cells.

It´s a disease caused by an arthropod born flavivirus, carried by mosquitoes, who cause encephalitis that affect humans and animals, such as horses, sometimes with fatal results.
