Coagulase-positive staphylococci are the most pathogenic strain. Coagulase-negative staphylococci are currently known to include more than thirty other species. They are general commensals of the skin, although some types cause infections. Commensal is a type of life in which one living thing benefits and the other is not affected by this partnership in the symbiosis of two organisms. There are two positive species of coagulase-positive staphylococci: Staphylococci aureus and staphylococci intermedius are coagulase-positive, all other staphylococci are coagulase-negative. Positive staphylococci are salt tolerant and require biotype analysis for identification.
Bacteria of the genus Staphylococci are pathogens of humans and other mammals. Traditionally, they are divided into two groups according to their ability to coagulate blood plasma (coagulase reaction). Coagulase positive staphylococci constitute the most pathogenic strain of staphylococcus aureus. Coagulase-negative staphylococci are currently known to include more than thirty other species.
Staphylococci are bacteria that are about half to one μm in diameter. They grow in clusters, in pairs, and sometimes in short chains. Clusters arise by the division of staphylococci in two planes. Streptococci grown on solid media appear in clumps.
Staphylococcus aureus is notorious for causing boils, styes, and other superficial skin infections in humans. It also causes more serious infections, especially in chronic disease, traumatic injury, burns or frail people. These infections include pneumonia, deep abscesses, and meningitis and are usually associated with hospitalized patients rather than healthy individuals in the community.
"Counting of Coagulase Positive Staphylococci" is carried out in our laboratories in accordance with the legal regulations and standards related to TÜRKAK accreditation.
