¹Relative growth in skim milk broth, plated on BHI at day 21 of shelf life (storaged at 6°C): (−) <1 log cfu/mL, (+) 1–6 log cfu/mL, (++) >6 log cfu/mL.
²Isolate produced pinkish coloration of Skim Milk Agar.
³Isolates were tested for susceptibility against 16 antimicrobials included in the Gram positive NARMS panel (see Methods).
⁴Strain was considered too fastidious for susceptible testing.
