Targeted isolation of bacteria with potential to competitively exclude Staphylococcus aureus in the upper respiratory tract of pigs

Our study, using an anticorrelation based targeted approach, identified three L. lactis strains with weak negative correlation with S. aureus, suitable for in vivo safety and efficacy testing in pigs. These L. lactis strains may have the ability to be used safely to reduce LA-MRSA carriage in the nasal passages of pigs but further in vivo testing is necessary to confirm this potential.
