Staphylococcus aureus Rosenbach

Staphylococcus aureus Rosenbach refers to the specific strain or taxonomic designation of Staphylococcus aureus named after Friedrich Julius Rosenbach, the bacteriologist who first isolated and characterized Staphylococcus aureus in the late 19th century. This designation typically denotes the type strain or a reference strain of Staphylococcus aureus, which serves as a standard for scientific research, including studies on bacterial physiology, virulence, and antibiotic susceptibility. As a reference strain, Staphylococcus aureus Rosenbach exhibits the core characteristics of the species: it is a Gram-positive, coagulase-positive coccus that forms golden-yellow colonies on agar plates. It produces common virulence factors (e.g., hemolysins, enterotoxins) and is susceptible to non-beta-lactam antibiotics (unless modified). Its use as a reference ensures consistency across research studies, enabling comparisons of results between different laboratories. It also plays a role in validating diagnostic tests and developing new antibacterial agents, as it represents a well-characterized model of Staphylococcus aureus.
