PCV2 and Mycoplasma hyopneumoniae: co-infection and co-vaccination
Experimental Mhyo and PCV2 co-inoculations have resulted in somewhat divergent results.

PCV2 infection before and during an outbreak of PMWS on a pig farm in the UK
The findings of this study highlight the potential role of the immune status of the sow on the occurrence of PMWS.
Protective effect of the maternally derived porcine circovirus type 2 (PCV2)-specific cellular immune response in piglets by dam vaccination against PCV2 challenge
Maternally derived adaptive cellular immune responses play a critical role in protecting newborn piglets challenging PCV2 at 3 weeks of age.
Boehringer Ingelheim Animal Health sponsors PCV2 research projects with more than 400,000 euro
Since 2007, Boehringer Ingelheim Animal Health has funded independent European research projects related to Porcine Circovirus Type 2 (PCV2) infection and associated diseases. So far, 17 research projects have been awarded, each supported with 25,000 euro, in total 425,000 euro.
Spray-dried animal plasma on weanling pigs administered a PCV2 and M. hyopneumoniae vaccine strategy
Early administration of spray-dried animal plasma may stimulate feed intake in weanling pigs.
PCV2: Possible transmission to sows through artificial insemination and effects on quality of boar semen
PCV2 can be shed into semen by infected boars and research suggests that the virus can then be transmitted to gilts and sows by AI causing reproductive failure but there is no evidence that PCV2 in semen has effects on various characteristics of sperm cells.
PMWS: Disease progression and a proposal for herd case definition
Two conditions must be fulfilled to diagnose PMWS in a herd: a significant increase in postweaning mortality and PMWS must be diagnosed in at least one of three to five necropsied pigs.
Preventing disease: One billion pigs vaccinated with Ingelvac CircoFLEX®
Veterinarians and farmers across the globe have reached the landmark of protecting one billion pigs from the potentially devastating effects of Porcine Circovirus Disease (PCVD) using Ingelvac CircoFLEX®
Effect of sow and piglet porcine circovirus type 2 (PCV2) vaccination on piglet mortality, viraemia, antibody titre and production parameters
PCV2 vaccination was able to overcome this interference since the ADWG was improved.
Importance and monitoring of the genetic makeup of PCV2
Genomic changes can be associated with increased virulence or decreased immunogenicity.
Culturing and molecular methods to assess the infectivity of porcine circovirus from treated effluent of swine manure.
PCV2 viruses were able to resist the regular wastewater treatment.
Simultaneous PCV2 and Mycoplasma hyopneumoniae co-inoculation does not potentiate disease in conventional pigs
Under the conditions of the present study, concurrent inoculation of PCV2 and Mhyo did not result in potentiation of clinical signs and lesions attributed to either infection.
Update on the diseases associated with the PCV2: clinic, diagnosis and control
The PCV2 has been associated, in an ongoing way and throughout time, with more pathologies called, collectively, diseases associated with the PCV2 (PCVDs): PCV2 systemic disease, PCV2 lung disease, PCV2 enteric disease, PCV2 reproductive disease,PCV2 subclinical infection and porcine dermatitis and nephropaty syndrome.
Infectious risk factors for individual postweaning multisystemic wasting syndrome (PMWS) development in pigs from affected farms in Spain and Denmark.
The present study reflects the complex interaction among different pathogens and their effects in order to trigger PMWS in PCV2 infected pigs.
Updating on the epidemiology of PCV2 and implications
Novelties about the excretion routes, the transmission routes, the risk factors, etc., and explanation about how the PCV2 becomes a pathogenic virus.
Cost of post-weaning multi-systemic wasting syndrome and PCV2 subclinical infection – a stochastic economic model
The model highlights the importance of the cost of subclinical cases, usually understimated.
