  1. The interpretations of Flexicult Vet A by clinical staff and by the investigator are compared to the laboratory results obtained by broth microdilution (reference standard). A slash line is used to separate the results obtained by clinical staff (on the left) when they differed from those by the investigator (on the right)
  2. AMP ampicillin, AMC amoxicillin-clavulanate, CEF cephalotin, ENR enrofloxacin, SXT trimethoprim-sulfamethoxazole
  3. aOther species: Proteus mirabilis (n = 2), Staphylococcus pseudintermedius (n = 1), Enterococcus faecalis (n = 1), Klebsiella pneumoniae (n = 2), and Pseudomonas aeruginosa spp. (n = 1)
  4. bCefazolin was used instead of cephalotin for testing susceptibility to 1st generation cephalosporins by the reference standard method
  5. cOne Enterococcus isolate intermediate to enrofloxacin according to the reference standard was not included in the analysis of enrofloxacin susceptibility
  6. dThe values 8 and 4 represent amoxicillin and clavulanate, respectively
  7. eThe values 2 and 38 represent trimethoprim and sulfamethoxazole, respectively
