    Staphylococcus aureus is the most common cause of healthcare-associated bacteremia in North and South America and is also an important cause of community-acquired bacteremia. [14] Skin ulceration or wounds, respiratory tract infections, and IV drug use are the most important causes of community-acquired staph aureus bacteremia.

  3. Sepsis - Wikipedia

    en.wikipedia.org/wiki/Sepsis

    Diastolic blood pressure falls during the early stages of sepsis, causing a widening/increasing of pulse pressure, which is the difference between the systolic and diastolic blood pressures. If sepsis becomes severe and hemodynamic compromise advances, the systolic pressure also decreases, causing a narrowing/decreasing of pulse pressure. [23]

    Staphylococcus spp. also inhabit human skin, but they are facultative anaerobes. They ferment sugars, producing lactic acid as an end product. Many of these species produce carotenoid pigments, which color their colonies yellow or orange. Staphylococcus aureus is a major human pathogen. It can infect almost any tissue in the body, frequently ...

    Staph infections have a multitude of different causes, such as: Open wounds – This is by far the biggest cause of staph infection. Any open wound, even ones as small as a paper cut, are vulnerable to being infected. Staph bacteria will enter the body through any open wound, so it is important to properly treat, disinfect, and bandage any wounds.

    In healthcare, the risk of more serious staph infection is higher for patients in intensive care units (ICUs), patients who have undergone certain types of surgeries and patients with medical devices inserted in their bodies. [25] Staphylococcus aureus has emerged as a leading agent of sepsis. It facilitates factors such as tissue adhesion ...

  7. Septic shock - Wikipedia

    en.wikipedia.org/wiki/Septic_shock

    Septic shock is a result of a systemic response to infection or multiple infectious causes. The precipitating infections that may lead to septic shock if severe enough include but are not limited to appendicitis, pneumonia, bacteremia, diverticulitis, pyelonephritis, meningitis, pancreatitis, necrotizing fasciitis, MRSA and mesenteric ischemia.

  8. Streptococcus pyogenes - Wikipedia

    en.wikipedia.org/wiki/Streptococcus_pyogenes

    The main criterion for differentiation between Staphylococcus spp. and Streptococcus spp. is the catalase test. Staphylococci are catalase positive whereas streptococci are catalase-negative. [2] S. pyogenes can be cultured on fresh blood agar plates.

  9. Pyaemia - Wikipedia

    en.wikipedia.org/wiki/Pyaemia

    Pyaemia (or pyemia) is a type of sepsis that leads to widespread abscesses of a metastatic nature. [1] It is usually caused by the staphylococcus bacteria by pus-forming organisms in the blood. Apart from the distinctive abscesses, pyaemia exhibits the same symptoms as other forms of septicaemia.
