Staphylococcus haemolyticus
Staphylococcus haemolyticus
Staphylococcus haemolyticus (pronunciation: staf-uh-lo-kok-us hee-muh-lit-ik-us) is a species of Gram-positive bacteria that is part of the Staphylococcus genus. It is known for its role in human infections, particularly in hospital environments.
Etymology
The name Staphylococcus haemolyticus is derived from the Greek words "staphyle" meaning a bunch of grapes, "kokkos" meaning a berry, and "haemolyticus" referring to the destruction of red blood cells. This is in reference to the bacteria's grape-like shape and its ability to lyse red blood cells.
Description
Staphylococcus haemolyticus is a coagulase-negative staphylococcus (CoNS). It is part of the normal flora of the human skin but can also be an opportunistic pathogen, causing infections in individuals with compromised immune systems. It is known for its resistance to multiple antibiotics, making infections difficult to treat.
Clinical Significance
Staphylococcus haemolyticus is often associated with hospital-acquired infections, particularly in patients with indwelling medical devices such as catheters and prosthetic implants. It can cause a range of infections including bacteremia, endocarditis, and septicemia. Its high level of antibiotic resistance, including to methicillin, makes it a significant concern in healthcare settings.
