Staphylococcus pseudintermedius strain ST525 1

Staphylococcus pseudintermedius strain ST525 is a Gram-positive bacterium characterized by its cocci shape and cluster arrangement. This strain is facultatively anaerobic, meaning it can grow in both the presence and absence of oxygen, but its optimal growth temperature is notably low at 3°C, indicative of its mesophilic nature. It possesses flagella, although it is non-motile, which is a unique trait within its genus. This strain is found in host-associated habitats and has a diverse range of hosts, including Homo sapiens, various metazoans, viridiplantae, Canis lupus familiaris (domestic dogs), Felis catus (domestic cats), Phocidae (seals), Carnivora, Equidae (horses), and Caniformia (dog-like carnivores). The bacterium has been associated with numerous health issues in these hosts, including skin and soft tissue infections, abortion, infertility, pyoderma, otitis externa, dermatitis, neonatal mortality, and external ear otitis. S. pseudintermedius strain ST525 is classified as free-living and contains one replicon and one membrane. Its ability to thrive in various host environments underscores its ecological versatility. The range of health effects it can cause highlights its significance in veterinary and human medicine, particularly in the context of zoonotic transmission and the rising concerns over antibiotic resistance in Staphylococcus species. Understanding the biology and ecology of this strain can inform prevention and treatment strategies in both veterinary and medical settings.
