^aND, not determined. +, positive; −, negative.

^bData from references 3 and 5.

^cResults for the SPS disk were resistant for Bifidobacterium spp. (6).

^dAccording to the result of reference 2 (using API rapid ID 32S bioMérieux), no discrepancies were observed in our strains using Rosco diagnostic tablets.
