Koagulaasinegatiivsed
Koagulaasinegatiivsed refers to a group of bacteria that do not produce the enzyme coagulase. This enzyme is a virulence factor primarily associated with Staphylococcus aureus, enabling it to clot plasma. The absence of coagulase is a key characteristic used in the laboratory to differentiate S. aureus from other staphylococcal species, which are collectively known as coagulase-negative staphylococci (CoNS).
Coagulase-negative staphylococci are a diverse group, with Staphylococcus epidermidis and Staphylococcus saprophyticus being among the most
Common infections caused by CoNS include skin and soft tissue infections, urinary tract infections (especially in
