Horsepox virus (HSPV)
S0173 - Ultrasensitive qualitative detection of horsepox virus by
real time polymerase chain reaction.
Horsepox is a disease caused by a poxvirus in the genus
Orthopoxvirus, which also includes cowpox and vaccinia viruses.
Horses of all ages can be infected with this virus. Infected
horses develop typical pox lesions on the lower limbs or around
the muzzle. Two main forms of classical horsepox disease are
recognized: the buccal form and the ‘grease’ form. The buccal
form is clinically more severe than the grease form because
infected horses with the grease form may not be systemically
The disease is often transmitted by direct contact with an
infected host or with contaminated grooming equipment or other
fomites. However, the virus may also gain access to the body via
the respiratory tract. Upon infection, the virus may disseminate
to skin and other target organs. The virus causes degenerative
changes in the epithelium due to virus replication, resulting in
the development of vesicular lesions.
Diagnosis of horsepox infection may be by the
presentation of symptoms. Confirmation of the diagnosis was
traditionally done using culture, but this method is slow.
However, confirmation by PCR is rapid, specific and sensitive
