Porcine circovirus type 1
- Ultrasensitive detection of porcine circovirus type 1 by real time PCR
Porcine circoviruses (PCVs)
are single-stranded nonenveloped DNA viruses containing an
unsegmented circular genome protected by an icosahedral viral
capsid. The whole virus is approximately 17nm in diameter.
PCVs belong to the family
circoviridae and are considered the smallest viruses replicating
autonomously in the nucleus of infected eukaryotic cells; they
use the host polymerase for genome amplification. Two strains of
porcine circovirus have been identified, type 1 and type 2.
PCV type 1 was first
identified in 1974 and is not known to cause disease in swine,
there is circumstantial evidence that PCV1 may be
involved in congenital tremors.
type 1 recently garnered media attention because the virus was
discovered in some human vaccines (Baylis et al., 2011), raising
concerns about contamination in human vaccine production.
Diagnosis of PCV type 1
infection usually relies on molecular detection (eg polymerase
chain reaction), which gives high sensitivity and specificity.

specimen acceptability and shipping instructions.
specimen types, if there will be a delay in shipping, or during
very warm weather, refrigerate specimens until shipped and ship
with a cold pack unless more stringent shipping requirements are
specified. Frozen specimens should be shipped so as to remain
frozen in transit. See
