). Like other penicillin antibiotics, ampicillin acts against bacteria by inhibiting the synthesis of bacterial cell wall components.

We defined 3 mutually exclusive categories of clinically important resistance according to results of testing for ceftriaxone, ciprofloxacin, and ampicillin (Figure 1) (8,19): ceftriaxone/ampicillin resistance indicates resistance to ceftriaxone and ampicillin (because all ceftriaxone-resistant isolates are ampicillin resistant); ciprofloxacin nonsusceptibility indicates nonsusceptibility to ciprofloxacin but susceptibility to ceftriaxone; and ampicillin-only resistance indicates resistance to ampicillin but susceptibility to ceftriaxone and ciprofloxacin.
The aim of the present study was to determine antimicrobial susceptibility profiles of ampicillin resistant enterococci from dogs and cats' rectal swab samples and the occurrence of five virulence determinants in those isolates.
