Isolation, Genome Phylogenetic Analysis and In vitro Rescue of a Newly Emerging Porcine Circovirus Type 2 [PDF]
Porcine circovirus type 2 (PCV2) is the major causative agent of post-weaning multisystemic wasting syndrome (PMWS). Infection by PCV2 may cause heavy losses in pig industry.

Pathogenesis and Transmission of a Reassorted H1 Influenza A Virus Detected in North American Swine
ABSTRACT Background The USDA influenza A virus in swine national surveillance plan identified an increase in the detection frequency of a group of swine 1A.1.1.3 hemagglutinin (HA) clade viruses. This change was associated with reassortment events that resulted in new neuraminidase (NA) gene pairings.

Objectives: This study investigated the dynamics of porcine circovirus type 2 (PCV2) and PCV3 on a commercial farm following PCV2 vaccination. Methods: Serum samples from 35 pigs, starting at 3 weeks of age, were collected weekly until 21 weeks of age. Oral fluids from six pens of pigs of the same age were also analyzed.

(A) Cells infected with PCV2 (MOI = 1) were fixed for the TUNEL assay at 72 hpi and immunostained for viral proteins. Apoptotic cells (green), PCV2 Cap proteins (red), CSFV E2 proteins (blue) and nuclei (grey) are shown.

Background Vaccination is considered as an effective and economical way to against PCV2 infection. However, some of commercial available vaccines are based on inactivated viruses, while the others are based on purified protein of PCV2.

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

Six key viral pathogens—porcine epidemic diarrhea virus (PEDV), transmissible gastroenteritis virus (TGEV), porcine rotavirus (PoRV), porcine deltacoronavirus (PDCoV), pseudorabies virus (PRV), and porcine reproductive and respiratory syndrome virus (PRRSV)—inflict substantial economic losses on the global swine industry.

Porcine reproductive and respiratory syndrome (PRRS) remains one of the most economically significant viral diseases affecting the global swine industry, and currently available commercial vaccines provide only limited protection against circulating PRRS virus (PRRSV) strains. Therefore, alternative vaccination strategies are urgently needed to enhance

The Evaluation of a Porcine Circovirus Type 2 (PCV2) Intradermal Vaccine Against a PCV2 Field Strain
Background/Objectives: Porcine circovirus type 2 (PCV2) has a major impact on swine productivity. Vaccines are used to aid in control and mitigate production losses. We investigated the protection provided by an intradermal PCV2 vaccine against a field strain in Taiwan. Methods: We conducted a safety and efficacy study.
