Genetic Stability of a Genetically-Engineered Chimeric Porcine Circovirus (PCV) Vaccine, PCV1-2
… porcine circoviruses: porcine circovirus type 1 (PCV1) was discovered as a contaminant of porcine kidney (PK-15) cells and was determined to be nonpathogenic in swine; whereas porcine circovirus type 2 (PCV2) is pathogenic. A recently released vaccine for PCVAD was generated by inserting the gene …

Novel approaches towards vaccine developments against porcine circovirus type 2 and porcine reproductive and respiratory syndrome virus
… Two types of porcine circovirus (PCV), PCV1 and PCV2, have been identified thus far. PCV1, first identified as a contaminant of the PK-15 cell line, is non-pathogenic and has a low prevalence in swine herds. PCV2 is highly prevalent in most swine-producing countries and is associated …

Molecular Pathogenesis and Development of a Genetically Engineered Vaccine for Type-2 Porcine Circovirus
… the ubiquitous porcine circovirus type 1 (PCV1) is nonpathogenic for pigs. Since its initial detection in a Canadian commercial swine herd in 1991, PMWS has been detected in all swine producing regions of the world and is now a serious economic problem to the swine industry. The objectives …

Persistent viruses in Capsicum annuum plants: Understanding the mystery guests
… or the partitiviruses pepper cryptic virus 1 (PCV1) or PCV2. Plants infected with these viruses harboured similar viral RNA levels in all tissues, consistent with previous studies. I investigated virus-virus interactions between persistent viruses and two pathogenic viruses. Tobacco mosaic …

Molecular mechanisms of porcine circovirus 2 replication and pathogenesis
The non-pathogenic porcine circovirus type 1 (PCV1) was originally isolated as a persistent contaminant of the porcine kidney cell line PK-15. Whereas, porcine circovirus type 2 (PCV2) causes postweaning multisystemic wasting syndrome (PMWS) in pigs, which is devastating to the swine industry. My …
