Immune modulation mechanisms of porcine circovirus type 2
Porcine circovirus associated disease (PCVAD) is an umbrella term for a multitude of diseases and syndromes that have a negative impact on the health and economics of pig production operations throughout the world. Porcine circovirus type 2 is the causative agent of PCVAD; however the presence of …

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 …

Molecular Breeding of Porcine Circovirus Type 2 by Synthetic DNA Shuffling
Porcine circovirus type 2 (PCV2) is a small, non-enveloped, single-stranded DNA virus that causes disease in pigs and is an economically important pathogen affecting pig populations worldwide. PCV2 contains two major open reading frames (ORF): ORF1 encodes two replicase proteins and ORF2 encodes …

Genetic Stability of a Genetically-Engineered Chimeric Porcine Circovirus (PCV) Vaccine, PCV1-2
Porcine circovirus type 2 (PCV2) is the primary causative agent of porcine circovirus associated disease (PCVAD), an economically important swine disease that causes wasting in pigs 5-18 weeks of age. There exist two different types of porcine circoviruses: porcine circovirus type 1 (PCV1) was …

Molecular Pathogenesis and Development of a Genetically Engineered Vaccine for Type-2 Porcine Circovirus
Porcine circovirus type 2 (PCV2) is the primary causative agent of postweaning multisystemic wasting syndrome (PMWS), whereas 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 …

Using single cell RNA sequencing to assess immunological responses in quails injected with porcine circovirus-like particles
… for future studies. This study aimed at using porcine circovirus type 2 (PCV-2) to assess the evolution of the immune response of quails using single cell RNA sequencing (scRNA-seq) and computational methods. PCV-2 has a single stranded circular DNA genome that encodes the single capsid protein …

Novel approaches towards vaccine developments against porcine circovirus type 2 and porcine reproductive and respiratory syndrome virus
Porcine circovirus type 2 (PCV2) is the causative agent of porcine circovirus-associated disease (PCVAD). Porcine reproductive and respiratory syndrome (PRRS) is caused by PRRS virus (PRRSV). Both PCV2 and PRRSV have caused devastating diseases in the swine industry worldwide, resulting in immense …

Porcine circovirus associated disease: Modulation of the host immune response to PCV2 and PRRSV by regulatory T cells
Porcine circovirus associated disease (PCVAD) is currently one of the most economically important diseases facing the global swine industry. Porcine circovirus type 2 (PCV2) is the primary and essential causative agent of PCVAD, but development of clinical disease typically requires co-infection …

Development of a plant-made immunoassay for the detection of Porcine circovirus infections in South African swine herds
Porcine circovirus type 2 (PCV-2) is considered the major cause of porcine circovirusassociated diseases and is one of the major pathogens in swine producing countries. PCV-2 is a non-enveloped virus with a single stranded circular DNA genome of about 1.8 kb. This encodes the single capsid protein …

Effect of vaccination against porcine circovirus type 2 (PCV2) on ejaculate characteristics and the shedding of virus in boar semen
Research has demonstrated that porcine circovirus type 2 (PCV2) can be shed into boar semen, raising the possibility that artificial insemination may be an important route by which disease associated with PCV2 is transmitted. The objective of this experiment was to determine the effect of …

Effect of viral and host genetics on pcv2 replication in lymphoblasts and clearance by monocytes
Porcine circovirus type 2 (PCV2), a very small, circular, single-stranded DNA virus, is the major etiologic agent of porcine circovirus-associated diseases (PCVADs) and is widely prevalent in swine herds. It causes significant economic losses to the global pig industry. Three major PCV2 genotypes …

Perfil sorológico e virêmico de suínos da raça Piau e linhagem comercial naturalmente infectados com o Porcine circovirus 2 em diferentes fases de produção
As doenças associadas ao PCV2 (PCVAD) necessitam de vários fatores para ocorrer, no entanto, a infecção pelo vírus é fundamental para o desenvolvimento de qualquer uma das síndromes. O presente estudo teve como objetivo verificar diferenças nos perfis sorológicos e virêmicos para o PCV2 entre …

Construction and evaluation of three candidate vaccines expressing HIV-1 subtype-C mosaic Gag
… transgenes due to a novel enhancer element from porcine circovirus type 1, which has been demonstrated to increase gene expression. The third vaccine vector selected was the well characterised poxvirus modified vaccinia Ankara (MVA).

Effect of circovirus vaccination on immune responses, viral load, and growth performance of pigs under field conditions
Vaccination against porcine circovirus type 2 (PCV2) has become a standard practice to improve pig mortality and growth rate in PCV2-affected herds. Unfortunately, there has been little field-based research evaluating factors which affect circovirus vaccination. The focus of this research was on …

Avaliação da co-infecção do circovirus suíno 2 com Mycoplasma hyopneumoniae em amostras de pulmões coletadas em abatedouro
A circovirose suína, causada pelo circovirus suíno tipo 2 (PCV2), e a pneumonia enzoótica suína, causada pelo Mycoplasma hyopneumoniae, são doenças infecto-contagiosas de grande importância na suinocultura mundial, ambas causam pneumonias com diferentes formas de apresentação. Têm distribuição …
