Staphylococcus pseudintermedius strain MAD401

Staphylococcus pseudintermedius strain MAD401 is a Gram-positive cocci that typically arranges itself in clusters or singles. This bacterium is facultatively anaerobic, allowing it to thrive in varying oxygen levels, and is classified as mesophilic, with an optimal growth temperature of 3°C. Staphylococcus pseudintermedius is non-motile, lacking flagella, which indicates a reliance on host interactions for dispersal and colonization. This strain is primarily associated with various hosts, including Homo sapiens (humans), Canis lupus familiaris (domestic dogs), Felis catus (domestic cats), and several other Metazoa and even some Viridiplantae. Its presence in diverse hosts suggests a significant ecological role, particularly in domestic environments where it may contribute to both normal flora and opportunistic infections. S. pseudintermedius strain MAD401 is known to be involved in several health issues, including skin and soft tissue infections, abortion, infertility, pyoderma, otitis externa, dermatitis, and neonatal mortality. These health effects highlight its potential pathogenicity, especially in domestic animals and occasionally in humans. Given its free-living biotic relationship and the variety of hosts it can inhabit, S. pseudintermedius strain MAD401 serves as a pertinent example of how microorganisms can adapt to and affect multiple biological systems. Understanding its habitat and pathogenic capabilities is crucial for developing strategies to manage infections it may cause, particularly in veterinary and human health contexts. The strain is cataloged under the accession number NZ_CP039742.1.
