Methicillin resistance in Staphylococcus pseudintermedius and Staphylococcus aureus strains isolated from companion animals.

Introduction: The increasing interest for staphylococci in Veterinary medicine highlights the need to have an accurate identification of these bacteria. Furthermore, the control of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant Staphylococcus pseudintermedius (MRSP) requires a dual approach aimed at reducing antimicrobial consumption and preventing transmission between animals and from animals to humans or viceversa. In this study, we have isolated Staphylococcus aureus and Staphylococcus pseudintermedius strains from infection sites of companion animals and we evaluated the degree of identity of these isolates comparing different identification methods.
