7 Δεκ 2023 · One common infection marker in blood tests is the presence of elevated white blood cell count, also known as leukocytosis. White blood cells are a crucial component of our immune system, and their levels increase in response to an infection.
What do the results of a Gram stain mean? Gram stain test results reveal one of two categories: a negative Gram stain or a positive Gram stain. This is not to be confused with gram-negative bacteria or gram-positive bacteria.
Bacteria in the genus Staphylococcus are pathogens of man and other mammals. Traditionally they were divided into two groups on the basis of their ability to clot blood plasma (the coagulase reaction). The coagulase-positive staphylococci constitute the most pathogenic species S aureus.
13 Απρ 2016 · The coagulase test can be used to differentiate between Staphylococcus aureus and other Staphylococcus species. If the coagulase test is positive, the bacteria is likely Staphylococcus aureus; if it is negative, the bacteria is likely Staphylococcus epidermis or Staphylococcus saprophyticus.
What does it mean if your Staphylococcus aureus result is too high? An elevated Staphylococcus aureus level on a GI-Map panel indicates an overgrowth of this bacterium in the gastrointestinal (GI) tract.
Staphylococcus aureus infections range from mild to life threatening. The most common staphylococcal infections are. However, the bacteria can travel through the bloodstream (called bacteremia) and infect almost any site in the body, particularly heart valves (endocarditis) and bones (osteomyelitis).
Staphylococci are gram-positive aerobic organisms. Staphylococcus aureus is the most pathogenic; it typically causes skin infections and sometimes pneumonia, endocarditis, and osteomyelitis. It commonly leads to abscess formation. Some strains elaborate toxins that cause gastroenteritis, scalded skin syndrome, and toxic shock syndrome.
