Porcine Circo Virus Infection
How is PCV2 diagnosed?
Clinically generalised haemorrhages on body, abortions and foetuses are mummified.
Confirmed after lab . Diagnosis.
PCV2 infections can be readily diagnosed at most laboratories that are accustomed to working with pigs. It is important to remember that PCV2 infection is widespread in most pig populations but only causes disease in a low percentage of farms.
Differential Diagnosis
1. Classical Swine fever ( High fever and purple haemorrhagic patches on extremities of the body)
2. ASF ( same as CSF )
3. Swine Erysipelas( diamond shaped lesions on the body )
How do I treat pigs with PCV2-associated diseases?
Because the organism is a virus, antibiotic therapy is often not helpful. However, because PCV2 rarely acts alone, treatment strategies should be aimed at reducing the prevalence of other common diseases or infections such as PRRS virus, parvovirus, Mycoplasma hyopneumoniae, and Streptococcus suis. Good production practices such as all-in, all-out pigflow, proper environmental control, and sanitation and disinfection of facilities will also help to minimize the effects of the disease.
Is there a vaccine available for PCV2?
No vaccine is currently available though several research groups are working on their development.
How do I keep the PCV2 off my farm?
PCV2 has a worldwide presence and it is likely that your pigs have already been exposed to the virus. Researchers are continuing efforts to better understand why most farms are infected yet relatively few experience PCV2-associated losses. Enforcing strict biosecurity and farm security protocols will minimize the risk of introducing additional viruses or synergistic disease agents that may trigger PCV2 to become clinically significant.
