In addition, a murine methicillin-resistant Staphylococcus pseudintermedius (MRSP) skin infection model was established to evaluate the therapeutic efficacy of SAN. In vitro assays revealed that the MIC and MBC of SAN against S. pseudintermedius were 39.06 \u03bcg\u02d9mL-1 and 156.25 \u03bcg\u02d9mL-1. SAN could delay MRSP entry into the logarithmic growth phase and disrupt the bacterial structure. Transcriptomic analysis revealed that SAN primarily impacted amino acid synthesis and metabolism. In a murine MRSP skin infection model, SAN significantly reduced bacterial load, increased serum IL-4 expression, and decreased IL-6 expression. Histopathological analysis showed reduced inflammation and improved skin structure in the SAN group, with abundant fibroblasts and macrophages.<\/jats:p>\n               <\/jats:sec>\n
