- Ultrasensitive qualitative detection of bovine parvovirus by
real time polymerase chain reaction
polyomavirus (BPyV) is
a double-stranded DNA virus of genus Polyomavirus, of which
SV40, a DNA transforming virus, is also a member. The virus is
non-enveloped, with a diameter of 40-50 nm. Members of the
Polyomavirus genus usually contain circular dsDNA about 5 kb in
size, associated with cellular histones in a chromatin-like
complex. The viral genome encodes for 5-9 proteins. Occasionally
the viral genome can integrate into the genome of the host cell,
which can cause tumor formation in susceptible host animals.
Bovine polyomavirus was
originally found in fetal rhesus monkey kidney cells and was
thought to be simian polyomavirus until scientists confirmed
that it originated from the fetal calf serum that was used to
culture these cells. Genomic sequence for bovine polyomavirus has subsequently been detected
with high frequency in bovine sera, regardless of geographic
region of origin (Shuurman et al., 1991; Wang et al., 2005).
Culture detection of
this virus by cell culture method is not very sensitive and
requires a long time to complete. Detection by PCR is highly
sensitive, specific and rapid.
