Equine Infectious Anaemia (EIA)
Disease causing agent
equine infectious anaemia virus
Transmission
large horse biting flies from infected to non-infected horses
via infected blood products and blood contaminated equipment,
including contaminated needles and syringes
Signs you will see
recurring fever, anaemia, fluid retention, weight loss and death
Diagnosis
detection of antibodies to EIA in blood (Coggins test)
Treatment
no treatment effective or allowed - compulsory slaughter and disposal of
affected horse
Prevention
insect repellent and mesh to prevent transmission by biting flies
ensure responsibly sourced and certified blood products and blood test
imported horses
no vaccine available
Equine Viral Arteritis (EVA)
Disease causing agent
equine arteritis virus
Transmission
during mating or artificial insemination, contact with products from
abortion/ foaling, via droplets from the respiratory tract
Signs you will see
abortion, fever, depression, lethargy, stiff movement, runny nose,
conjunctivitis, swelling of the lower limbs, sheath, udder, tummy or
around the eyes
stallions can become life-long shedders of virus in their semen
without clinical signs
Treatment
no specific treatment, only supportive care
Prevention
establishment of freedom from infection before breeding activities
commence by blood test for mares and blood test and vaccination for
stallions and teasers
Contagious Equine Metritis (CEM)
Disease causing agent
bacteria
Taylorella equigenitalis, Klebsiella pneumoniae
and
Pseudomonas aeruginosa
Transmission
during mating, infected semen for AI, on hands and instruments
Signs you will see
mares show discharge from the vulva
some mares and most stallions do not show signs and become silent carriers
Treatment
antibiotics and antiseptic washes to the affected area
swabbing following treatment
Prevention
ensure mares and stallions are free from infection prior to and remain free during breeding activities by
swabbing procedures as recommended in HBLB codes of practice (http://codes.hblb.org.uk)
strict hygiene when handling breeding mares and stallions, wear gloves, use separate utensils
Contaminated needles, syringes
and blood products can be
involved in the spread of equine
infectious anaemia.
Semen used in artificial
insemination can be a potential
source of EVA and CEM. It is
therefore important to ensure the
appropriate health certificates
accompany the semen.
