hemolysin

Thân thiện

A scientist observes hemolysin activity in a petri dish.

Definition

Noun: A hemolysin is any substance, often a toxin or antibody, that can cause lysis (the rupture or destruction) of erythrocytes (red blood cells), resulting in the release of their hemoglobin into the surrounding fluid.

Usage

The term is used primarily in medical, biological, and toxicological contexts to describe agents that damage red blood cell membranes. * The bacterial toxin was identified as a potent hemolysin. * Researchers are studying the hemolysin produced by the pathogen to understand its role in infection.

Advanced Usage

• Alpha-hemolysin vs. Beta-hemolysin: In microbiology, these terms describe types of hemolysins based on their effect on blood agar plates. Alpha-hemolysin causes partial lysis (greening), while beta-hemolysin causes complete lysis (clearing).
• Immune-mediated hemolysis: Some hemolysins are antibodies that bind to red blood cells and trigger their destruction by the immune system, as seen in certain diseases.

Variants and Related Words

• Hemolysis (noun): The process or event of red blood cell destruction.
  • The test confirmed intravascular hemolysis.
• Hemolytic (adjective): Having the property of causing hemolysis.
  • It is a hemolytic toxin.
• Hemolysin is synonymous with haemolysin (British English spelling).

Synonyms

• Erythrocytolysin
• Hemotoxin (specifically when referring to a toxin that lyses red blood cells)
