hemolysin

 [he-mol´ĭ-sin]
a substance that liberates hemoglobin from erythrocytes by interrupting their structural integrity.

he·mol·y·sin

(hē-mol'i-sin),
1. Any substance elaborated by a living agent and capable of causing lysis of red blood cells and liberation of their hemoglobin. Synonym(s): erythrocytolysin, erythrolysin
2. A sensitizing (complement-fixing) antibody that combines with red blood cells of the antigenic type that stimulated formation of the hemolysin, a fixing complement with the antibody-cell union resulting in lysis of the cells.

hemolysin

(hĭ-mŏl′ĭ-sĭn, hē′mə-lī′-)
n.
An agent or substance, such as an antibody or a bacterial toxin, that causes the destruction of red blood cells, thereby liberating hemoglobin.

hemolysin

[himol′əsin]
Etymology: Gk, haima + lysis, loosening
any one of the numerous substances that lyse or dissolve red blood cells. Hemolysins are produced by bacterial strains, including staphylococci and streptococci, and are contained in venoms and vegetables. Bacterial hemolysins are divided into those that are filterable and those that cluster around the bacterial colony on a culture medium containing red blood cells. Hemolysins appear to aid the invasive power of bacteria. Also spelled haemolysin. See also hemoglobin, hemolysis.

he·mol·y·sin

(hē-mol'i-sin)
1. Any substance elaborated by a living agent and capable of lysing red blood cells and liberating their hemoglobin.
Synonym(s): erythrocytolysin, erythrolysin, haemolysin.
2. A sensitizing (complement-fixing) antibody that combines with red blood cells of the antigenic type that stimulated formation of the hemolysin, so that complement fixes with the antibody-cell union and causes dissolution of the cells.
