- Abstract
Background: Mupirocin is a topical antibacterial drug used for the treatment of staphylococcal infections, including meticillin‐resistant <italic>Staphylococcus pseudintermedius</italic> (MRSP). The recent emergence of resistance to mupirocin is a major concern in many countries. Objectives: This study investigated the prevalence and genotype of mupirocin‐resistant <italic>S. pseudintermedius</italic> isolated from pet dogs with pyoderma. Samples: A total of 110 clinical isolates of <italic>S. pseudintermedius</italic> were collected from dogs with pyoderma (<italic>n</italic> = 110) between July 2010 and September 2016. All animals were client‐owned dogs. Methods: Low‐ and high‐level mupirocin resistance were evaluated with both the broth microdilution and disk diffusion tests. Mupirocin resistance in <italic>S. pseudintermedius</italic> isolates was confirmed by genetic analysis of the <italic>ileS‐2</italic> and naïve <italic>ileS</italic> genes. Results: MRSP and meticillin‐susceptible <italic>S. pseudintermedius</italic> were detected in 69 and 41 dogs, respectively. One MRSP strain was highly resistant to mupirocin and contained the high‐level mupirocin resistance gene <italic>ileS‐2</italic>. There were no low‐level mupirocin‐resistant isolates. Conclusion and clinical importance: Mupirocin is a useful topical antibacterial for MRSP, but a clinical MRSP isolate that had not previously been exposed to mupirocin exhibited the high‐level mupirocin resistance in phenotype and genotype. Therefore, continuous monitoring for mupirocin resistance is important in small animal practice.
