Figure 2

Counts of STEC strains during the cheese manufacture. AR2: 3 AR STEC strains, AS2: 3 NAR STEC strains, ARSSb2: 1 AR and 2 NAR STEC strains, ASRRa2: 2 AR and 1 NAR STEC strains. AR strains: black lines, symbols: ▵, ○, ×. NAR strains: grey lines, symbols: ▿, ⊠, ⋄. Step 1: milk prior to maturation, Step 3: cheese at moulding stage, Step 5: cheese after drying, Step 7: cheese at the end of ripening (20 days).
