  • a w, weak; +, positive; −, negative; R, resistant; S, susceptible; ND, not determined.

  • b Identification based on species-specific primers.

  • c Identification confirmed by using the sequence of the 16S rRNA gene.

  • d Logan et al. (31) reported that C. lanienae was able to reduce nitrite.

  • e Vandamme et al. (42) reported that 17% of A. butzleri isolates were susceptible to cephalothin.

  • f Vandamme and De Ley (41) reported that C. hyointestinalis was not able to reduce nitrite.
