Table 1 Antimicrobial sensitivity testing using a microdilution method to determine the minimal inhibitory concentration (MIC), except in additional oxacillin* testing, in which the disk diffusion method was used; all the tested Staphylococcus pseudintermedius isolates showed the same pattern of resistance

From: Staphylococcus pseudintermedius septicemia in puppies after elective cesarean section: confirmed transmission via dam’s milk
