  2. Hemolysin - Wikipedia

    en.wikipedia.org/wiki/Hemolysin

    Hemolysins or haemolysins are lipids and proteins that cause lysis of red blood cells by disrupting the cell membrane.Although the lytic activity of some microbe-derived hemolysins on red blood cells may be of great importance for nutrient acquisition, many hemolysins produced by pathogens do not cause significant destruction of red blood cells during infection.

  3. Bacteriuria - Wikipedia

    en.wikipedia.org/wiki/Bacteriuria

    The gold standard for detecting bacteriuria is a bacterial culture which identifies the concentration of bacterial cells in the urine. The culture is usually combined with subsequent testing using biochemical methods or MALDI-TOF, which allows to identify the causal [citation needed] bacterial species, and antibiotic susceptibility testing ...

  4. Hematuria - Wikipedia

    en.wikipedia.org/wiki/Hematuria

    Hematuria can be classified according to visibility, anatomical origin, and timing of blood during urination. [1] [6]In terms of visibility, hematuria can be visible to the naked eye (termed "gross hematuria") and may appear red or brown (sometimes referred to as tea-colored), or it can be microscopic (i.e. not visible but detected with a microscope or laboratory test).

  5. Urinary tract infection - Wikipedia

    en.wikipedia.org/wiki/Urinary_tract_infection

    In those who have bacteria or white blood cells in their urine but have no symptoms, antibiotics are generally not needed, [15] unless they are pregnant. [16] In those with frequent infections, a short course of antibiotics may be taken as soon as symptoms begin or long-term antibiotics may be used as a preventive measure. [17]

  6. Hemolysis - Wikipedia

    en.wikipedia.org/wiki/Hemolysis

    A red blood cell in a hypotonic solution, causing water to move into the cell A red blood cell in a hypertonic solution, causing water to move out of the cell. Hemolysis or haemolysis (/ h iː ˈ m ɒ l ɪ s ɪ s /), [1] also known by several other names, is the rupturing of red blood cells (erythrocytes) and the release of their contents into surrounding fluid (e.g. blood plasma).

  7. Hemolytic–uremic syndrome - Wikipedia

    en.wikipedia.org/wiki/Hemolytic–uremic_syndrome

    Atypical HUS (aHUS) represents 5–10% of HUS cases [5] and is largely due to one or several genetic mutations that cause chronic, uncontrolled, and excessive activation of the complement system, [5] which is a group of immune signaling factors that promote inflammation, enhance the ability of antibodies and phagocytic cells to clear microbes ...

  8. Hemolysis (microbiology) - Wikipedia

    en.wikipedia.org/wiki/Hemolysis_(microbiology)

    Beta-hemolysis (β-hemolysis), sometimes called complete hemolysis, is a complete lysis of red cells in the media around and under the colonies: the area appears lightened (yellow) and transparent. [1] Streptolysin, an exotoxin, is the enzyme produced by the bacteria which causes the complete lysis of red blood cells. There are two types of ...

  9. Urine - Wikipedia

    en.wikipedia.org/wiki/Urine

    Urobilin is a final waste product resulting from the breakdown of heme from hemoglobin during the destruction of aging blood cells. [12] [13] Colorless urine indicates over-hydration. Colorless urine in drug tests can suggest an attempt to avoid detection of illicit drugs in the bloodstream through over-hydration.
