  1. The livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) concentrations for two strains (S1 and S2) were estimated in broth and in the initial material samples (steel, plastic, concrete disk and concrete disk). The estimated broth concentrations were from single value and the estimated sample concentrations were mean concentrations from triplicate samples. The concentrations were calculated as viable counts on both 5% bovine blood agar and selective Oxoid Brilliance MRSA 2 agar
  2. aBA = 5% bovine blood agar, MRSA = selective Oxoid Brilliance MRSA 2 agar
