Detection of M. hyopneumoniae infections in live pigs is difficult for the producer, the field veterinarian and the diagnostician. This study was designed and performed with the objective to compare various samples types and diagnostic assays for their sensitivity to…
Critical appraisal of evidence that low-dose, long term (growth promotion) antimicrobial use augments public health risks from antimicrobial resistant organisms
Antimicrobials are important tools for ensuring the health, welfare and productivity of pigs raised for food. Banning of antimicrobial growth promotant use in Denmark, and subsequently more widely in the EU, has prompted many entities to seek more restricted availability…
Reverse Vaccinology and Genomics Towards Controlling Post-Weaning Diarrhea
Post-weaning diarrhea (PWD) in pigs is a continuing problem for the swine industry. The goal of this study was to utilize a concept known as reverse vaccinology towards the identification of novel vaccine candidates to be used towards the future…
Epidemiology of Staphylococcus aureus in multiple site pig farms
The aim of this study was to obtain basic information about the ecology of S. aureus on modern swine farms, based on in depth sampling of pigs in two multiple site systems. Samples were collected from the nose, tonsils, feces,…
Implementation of an integrated mapping service to support regional control and elimination of PRRS virus
There are approximately 20 regional PRRS projects in the United States in various stages of progress. Each coordinator has their own approach to the challenges of mapping the region, many depending on the assistance of a certain pharmaceutical company. The…
Impact of pigs entering a region on feasibility of PRRSv eradication
The goal of this project was to understand the impact of PRRS infected pigs on neighboring herds that are negative. In the original design, we proposed to collaborate with regional PRRS control projects and use data being collected to address…
Impact of Influenza vaccination of growing pigs on bioaerosol generation. Identification
The 2009 influenza pandemic and the recent H3N2v events have highlighted the constant threat that influenza viruses represent for people and animals. Because influenza viruses are shared between humans, avian and mammals, understanding interspecies transmission and the risk for influenza…
Demonstration of pathogenicity in CDCD pigs with a cytopathic agent isolated from farm with “Sow abortion and mortality syndrome”
Animal and Human Health Implications of Livestock Associated Methicillin-Resistant Staphylococcus aureus (MRSA)
The apparently recent emergence of ST398 MRSA in livestock populations in many countries is a valid cause of consternation, and the public health implications need to be better understood. However, in approximately seven years since being first recognized, the burden…
An evaluation of back-drafting of non-filtered air as a source of PRRSV infection to pigs housed in filtered facilities and whether selected intervention strategies can reduce this risk
The objectives of this study were to demonstrate that the risk of PRRSV-contaminated aerosols entering a facility via retrograde air is a true risk though unfiltered points (i.e. idle fans); to titrate the minimum air speed necessary to introduce PRRSV-contaminated…
