Oral Vaccination Reduces the Effects of Challenge on the Swine Small and Large Intestine Microbiome.

Porcine proliferative enteropathy remains one of the most prevalent diseases in swine herds worldwide. This disease is caused by , an intracellular bacterial pathogen that primarily colonizes the ileum. In this study, we evaluated changes to the microbiome of the ileal mucosa, ileal digesta, cecal digesta, and feces subsequent to challenge with and to an oral live vaccine against .

Effect of litter aggregation and pooling on detection of porcine reproductive and respiratory virus in piglet processing fluids.

A sampling technique has been validated to monitor porcine reproductive and respiratory syndrome virus 2 (PRRSV-2) using the serosanguinous exudate known as processing fluids (PFs) that accumulate from tissues obtained during tail docking and castration. PFs are an aggregate sample of large numbers of piglets and litters. However, little is known about the effect of litter aggregation on the ability of PCR to correctly classify an aggregated PF sample as positive.
