Emerging Challenges and Advances in Porcine Circovirus: A Decade in Review. [PDF]

Transbound Emerg Dis
Over the past decade, porcine circoviruses (PCVs) have continued to pose a significant threat to global swine health, and pivotal discoveries have significantly reshaped our understanding of their biology and control. Extensive genomic surveillance has expanded porcine circovirus 2 (PCV2) genotyping from four to at least eight lineages, with PCV2d now ...

Field Evaluation of a Novel Combined Vaccine Against Porcine Circovirus Types 2a/d, Mycoplasma hyopneumoniae and Mycoplasma hyorhinis With an Emphasis on Growth Performance. [PDF]

Vet Med Sci
A field trial on three commercial farms evaluated a combined vaccine targeting PCV2a/d, Mycoplasma hyopneumoniae, and Mycoplasma hyorhinis. Vaccinated pigs showed improved average daily weight gain, stronger immune responses against these pathogens, and significantly reduced viral and mycoplasmal loads and lesion severity, supporting its efficacy under

Emergence of a Novel CRESS-DNA Virus Associated with Swine Reproductive Failure in China. [PDF]

Transbound Emerg Dis
The continuous emergence of circular Rep‐encoding single‐stranded (CRESS) DNA viruses across diverse hosts has been closely associated with the occurrence of severe diseases. Four circoviruses within the genus Circovirus have been identified in pigs, including porcine circovirus Type 1 (PCV1), PCV2, PCV3, PCV4, and PCV5.

Effect of porcine circovirus type 2 (PCV2) vaccination on PCV2-viremic piglets after experimental PCV2 challenge [PDF]

Veterinary Research, 2014
Abstract The objective of this study was to evaluate the effect of porcine circovirus type 2 (PCV2) vaccines on PCV2-viremic and -seropositive piglets born from naturally PCV2-infected sows against postnatal PCV2 challenge. The experimental design was aimed at mimicking commercial swine rearing conditions to evaluate the response of the PCV2 ...

Effects of Porcine Circovirus Type 2 (PCV2) Maternal Antibodies on Experimental Infection of Piglets with PCV2 [PDF]

Clinical and Vaccine Immunology, 2005
ABSTRACTTo determine the effects of porcine circovirus type 2 (PCV2) maternal antibodies on and response to experimental PCV2 infection, 24 piglets were divided into four groups on the basis of the enzyme-linked immunosorbent assay titers of PCV2 maternal antibodies: group A (n= 6; sample/positive [S/P] ratio, <0.2), group B (n= 5;S/Pratio, >0.2 ...

Effect of Porcine Circovirus Type 2 (PCV2) Vaccination of the Dam on PCV2 Replication In Utero [PDF]

Clinical and Vaccine Immunology, 2009
ABSTRACTThe aims of this study were to determine if porcine circovirus type 2 (PCV2) vaccination of the dam is effective in preventing fetal PCV2 infection and reproductive failure. Twelve pregnant, PCV2-naïve sows were randomly divided into four groups, with three sows in each group.
