Towards controlling antimicrobial resistance in swine production systems: harnessing the paradoxical effects of micro-minerals and feed-grade antimicrobials on resistance in enteric bacteria
The present study was aimed at determining the effects of supplemental feed grade antimicrobials on the selection and co-selection of...

Occurrence and Movement of Antibiotic Resistant Bacteria and Resistance Genes in Tile-Drained Agricultural Fields Receiving Swine Manure Application
 The use of antibiotics by the swine industry to increase production efficiency and treat disease is thought to contribute to antibiotic resistance in the environment.  When manure from...

Effects of Subtherapeutic Antibiotics on Antibiotic Resistance and Virulence Gene Transfer in Swine Intestinal Bacteria
Subtherapeutic antibiotics have been used for decades as growth promotants and prophylactic agents. The following antibiotics are approved for use a feed additives in swine: tetracyclines,...

Analysis of in-plant Factors and Genotyping of Antimicrobial Resistance among Four Organisms Isolated from Swine Processing Plants
We investigated the role of factors within processing plants including environmental and body site sources for carriage of for food safety significant pathogens and dissemination of antimicrobial...

Tetracycline Concentrations and Circulation of tet Genes in Swine Feeding Operations and Adjacent Environments
Farm animal manure-associated, antibiotic (AB)-resistant microorganisms and genes encoding this resistance are viewed as important sources for the observed increase of AB resistance in humans and...

Relationship between Antibiotics in Water and Rates of Antimicrobial Resistance Gene Transfer
There is growing concern about the fate of antibiotics and antibiotic residues in the environment. These compounds can potentially have selective effects on bacteria, thus amplifying the resistance...

Efficacy of direct-fed microbials administered from lactation through the nursery as an alternative to antibiotics in swine diets: an evaluation of performance, gastrointestinal microbial populations, and immune response
Direct-fed microbials may hold promise as an alternative to growth promoting additions of antibiotics added to swine diets. A study conducted at the University of Arkansas evaluated the effects of...

Persistance of plasmid-encoded resistance genes in the gastrointestinal bacterial flora of swine
In the presence of antibiotics in the feed, pigs became readily colonized with E. coli resistant to the antibiotic ceftiofur. Some E. coli harboured the specific gene blaCMY-2, known to confer...

Effects of egg yolk antibiotics and antibiotic regimens on carriage and shedding of Salmonella Typhimurium
Salmonella may reside in pigs during all stages of growth and may later contaminate pork products, thus presenting a foodborne hazard for humans. Often, salmonella are passed among hogs during...
