Staphylococcus pseudintermedius strain ST496-2

Staphylococcus pseudintermedius strain ST496-2 is a Gram-positive bacterium characterized by its cocci shape and the arrangement of cells in clusters and singles. It is a facultative anaerobe, indicating its ability to grow in both the presence and absence of oxygen. This strain has a mesophilic temperature range, with an optimal growth temperature of 3°C. S. pseudintermedius is non-motile and possesses flagella, which may play a role in its interactions within host environments. The bacterium is associated with a variety of hosts, including but not limited to Homo sapiens, Canis lupus familiaris (domestic dogs), Felis catus (domestic cats), and various members of the Carnivora and Equidae families. This broad host range suggests a versatile ecological niche. In terms of biotic relationships, S. pseudintermedius strain ST496-2 is described as free-living, yet it is also associated with significant health effects in its hosts. It is implicated in a range of conditions, including skin and soft tissue infections, pyoderma, otitis externa, and even serious reproductive issues such as abortion and infertility. The presence of this bacterium in both animal and human hosts indicates its potential role in zoonotic transmission and highlights the importance of monitoring its prevalence in veterinary and clinical settings. The health implications associated with this strain underscore the need for further research into its pathogenic mechanisms and ecological interactions within host-associated environments.
