Scanning electron micrograph (SEM) of Staphylococcus haemolyticus, Gram-positive, vancomycin resistant (VRSH), coccus bacterium. S. haemolyticus is a coagulase-negative, catalase positive bacterium that can be found on normal human skin. It is also the second most common coagulase-negative staphylococci present in human blood. S. haemolyticus has a thick peptidoglycan cell wall outside of its membrane and therefore can be targeted by antibiotics that interfere with the peptidoglycan biosynthesis process. However, some strains have developed resistance to glycopeptide antibiotics, such as teicoplanin and vancomycin. S. haemolyticus can cause meningitis, skin or soft tissue infections, prosthetic join infections, or bacteraemia. Magnification: x4, 000 when shortest axis printed at 25 millimetres. |
