Concise summaries of published swine health and production research, organized for quick discovery.
In an experimental trial involving ten SPF miniature pigs, a PCV2d virus-like-particle vaccine markedly reduced viral detection after challenge, but farm effectiveness remains unproven.
Landrace pig T-lymphoblasts were more permissive to PCV2 than Piétrain cells, with endolysosomal trafficking differences that may contribute to cellular susceptibility.
U.S. PEDV sequence analysis showed predominance of non-S-INDEL viruses and two recent clades, while limited contemporary sequencing constrained stronger conclusions.
Three PRRSV variants differed in experimental infectivity, with L1C.5 requiring fewer infectious units to infect half of the pigs.
In mixtures containing modified-live vaccine and wild-type PRRSV, ORF5 Sanger sequencing primarily represented the dominant viral population and could mask a minority strain.
