Staphylococcus pseudintermedius

Staphylococcus pseudintermedius is a Gram-positive cocci that typically arranges itself in clusters or singles. This bacterium is non-motile and lacks flagella, which contributes to its specific ecological niche as it is host-associated and exhibits free-living characteristics. S. pseudintermedius is categorized as facultatively anaerobic, allowing it to thrive in varying oxygen conditions, and it demonstrates mesophilic temperature preferences, with optimal growth occurring at 3°C. This microbe has been identified as pathogenic primarily in animals, but it can also affect humans. The genetic makeup of S. pseudintermedius is supported by five replicons, with genome accessions including NZ_LR134267.1 and NZ_CP039745.1, among others, indicating a complex genetic structure that may contribute to its adaptability and pathogenic potential. Given its association with hosts and its ability to thrive under specific temperature conditions, S. pseudintermedius plays a significant role in the microbial flora of animals, particularly dogs, where it can be involved in both commensal and pathogenic relationships. Understanding this organism's traits is essential for exploring its impact on animal health and potential zoonotic implications.
