Treatment Outcome of Methicillin-Susceptible and Methicillin-resistant Staphylococcus Infection in Dogs and Cats

Abstract

Therapeutic methods and treatment outcome of methicillin-susceptible (MS) and methicillin-resistant (MR) Staphylococcus infection in dogs and cats were evaluated. MS staphylococci were susceptible to many antimicrobial drugs and most cases were resolved after mainly administration of cephalosporins. More than 90%, 52%, and 34% of the MR Staphylococcus intermedius group were susceptible to tetracycline antibiotics, chloramphenicol, and fosfomycin (FOM), respectively. More than 80% of MR coagulase negative staphylococci (CNS) were susceptible to tetracycline antibiotics and trimethoprim-sulfamethoxazole (ST), and 47～69% of MRCNS were susceptible to ofloxacin, CP, gentamicin, amikacin, and FOM. One-hundred percent, 80%, 67%, and 50% of MR Staphylococcus aureus (SA) were susceptible to ST, CP, GM, and doxycycline, respectively. Most cases of MR staphylococci were resolved after administration of these susceptible antimicrobial drugs.
