Staphylococcus haemolyticus strain ATCC 29970

Staphylococcus haemolyticus strain ATCC 29970 is a Gram-positive, cocci-shaped bacterium classified as a facultative anaerobe. This strain is a chemoheterotroph, meaning it derives its energy from organic compounds. It shows optimal growth at 37°C and falls within the mesophilic temperature range, indicating its preference for moderate temperatures. S. haemolyticus is non-motile and does not possess flagella. The strain contains two replicons, reflecting a complex genomic structure. It has been isolated from multiple habitats, indicating its versatility and adaptability in various environments. This bacterium is known to inhabit several hosts, including Homo sapiens (humans), Bos taurus (cattle), Metazoa (multicellular animals), Canis lupus familiaris (domestic dogs), Felis catus (domestic cats), and Phocidae (seals). This broad host range suggests that S. haemolyticus can thrive in diverse ecological niches, contributing to its role in both human and veterinary medicine. Health effects associated with S. haemolyticus strain ATCC 29970 include a variety of serious infections such as meningitis, skin and soft tissue infections, bloodstream infections, and bovine mastitis. Additionally, it is implicated in prosthetic joint infections, catheter-related bloodstream infections, and nosocomial meningitis. The strain's presence in both humans and animals underscores its potential as a zoonotic pathogen, reflecting its importance in public health and veterinary medicine. This highlights the need for ongoing surveillance and understanding of its pathogenic mechanisms to mitigate its health impacts.
