PCN:penicillin; Oxa:oxacillin; Cefox:cefoxitin; TMP-SMX:trimethoprim-sulfamethoxazole; Clinda:clindamycin; Tetra:tetracycline; Levoflox:levofloxacin; Vanc:vancomycin; Linez:linezolid; Rif:rifampicin; Tige:tigercycline; Teico:teicoplanin; S. aureus:Staphylococcus aureus; CoNS:coagulase-negative staphylococci; S. pseudintermedius:Staphylococcus pseudintermedius: L. lactis spp:Lactococcus lactis species; K. rhizophilia:Kocuria rhizophilia. - indicates “Not Tested.” * Antibiotics that were added to the testing panel 3 months into the study, % resistant/intermediate reported in table is based on number of isolates tested. ** Erythromycin susceptibility was concordant with clindamycin susceptibility except for one CoNS isolate that is clindamycin susceptible but erythromycin resistant. Two CoNS and no S. aureus isolates had inducible clindamycin resistance. ⤉ Moxifloxacin susceptibility was fully concordant with levofloxacin susceptibility.
