Leptospirosis is a disease of worldwide significance that
infects many domestic and wildlife animal species and humans.
The scientific name of the infecting organism is
Leptospira interrogans sensu
lato. Within this species there are many different
can be spread between animals through contact with infected
urine, venereal or placental transfer, or bite wounds. Indirect
transmission occurs through exposure of susceptible animals to
contaminated water sources, food, bedding or human hands.
can survive in manure up to 2 months. Stagnant or slow moving
water provides a suitable habitat; the organism can survive up
to 20 days in water. This explains why outbreaks often increase
during periods of flooding.
shivering and muscle tenderness are among the first signs of
acute infection. Rapid dehydration may develop subsequently. In
subacute infections, the animal usually develops a fever,
anorexia, dehydration, and increased thirst. Animals with liver
involvement may develop icterus. Conjunctivitis and recurrent
uveitis may occur in chronic infections. Breeding success can be
impacted because of increased risk of abortion and decreased
milk production in mares.
currently no approved equine vaccine for leptospirosis. Although
Leptospira infection can be diagnosed by change in antibody
titers, titers may be negative during early stages of critical
infection. Thus an alternative method is needed to provide a
quick diagnosis of the disease at this stage. Molecular
detection of PCR is rapid, highly sensitive and specific. It is
suitable for quick diagnosis even during the first few days of
