Prestudy isolates are designated with the number 1 following the animal ID and poststudy isolates are designated with the number 2 following the animal ID. Unshaded MICs indicate susceptibility, yellow-shaded MICs indicate intermediate susceptibility, and red-shaded MICs indicate resistant susceptibilities. When numeric MICs were not provided, S and R are used to designate susceptible and resistant results, respectively. Key: PEN, penicillin; OX/ME, oxacillin/methicillin; CEFO, cefovecin; CIP, ciprofloxacin; ENO, enrofloxacin; MBO, marbofloxacin; CLN, clindamycin; DX, doxycycline; FLOR, florfenicol. In addition, all isolates were susceptible to amoxicillin (>0.25), amoxicillin-clavulanic acid (>0.25), imipenem (S), cephalexin (>2), cefpodoxime (>2), amikacin (>2), gentamicin (>0.5), azithromycin (S), erythromycin (>0.25), mupirocin (>1), chloramphenicol (>4), TMS (>10), minocycline (>0.5), and rifampin (>0.03).
