- Ultrasensitive qualitative detection of bovine parvovirus by
real time polymerase chain reaction
Bovine parvovirus (BPV), also known as
haemadsorbing enteric virus, is a member of the parvovirus group.
There are three major species, BPV1, 2 and 3. The virus is a
single stranded DNA virus with a genome of about 5.5 kb, which
encodes seven major proteins.
BPV most commonly causes
diarrhea in neonatal calves and respiratory and reproductive
disease in adult cattle. Reproductive infection causes abortion
and the birth of weak or stillborn calves. Respiratory signs
include coughing, dyspnea and nasal discharge.
Serology has been used to diagnose infection of cattle by
this virus. However, since many cattle have been exposed to this
virus (Sandals et al., 1995), serologic methods may not be
sufficient for rapid diagnosis of recent exposure. Molecular
detection by PCR enables rapid, highly specific and sensitive
detection of the virus.
