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. However, hemolysins are often capable of lysing red blood cells in vitro. While most hemolysins are protein compounds, some are lipid biosurfactants.

  • إنزيمات الحالَّة الدموية (بالإنجليزية: Hemolysins)‏ هي ذيفانات خارجية (بالإنجليزية: exotoxins)‏ تنتجها البكتيريا وتؤدي إلى انحلال كرات الدم الحمراء معملياً.
  • Hämolysine (von Hämolyse) sind Stoffe, die bei Erythrozyten (rote Blutkörperchen) eine Lyse bewirken. Dabei wird die Zellmembran der Erythrozyten perforiert und das Zytosol läuft aus. Dadurch gehören die Hämolysine zu den Toxinen.
  • Las hemolisinas son sustancias que producen lisis de los eritrocitos, mediante la producción de poros en la membrana citoplasmática. La mayoría de ellas son proteínas o lípidos.​​Son un factor de virulencia de Staphylococcus aureus, Vibrio parahaemolyticus, Streptococcus pyogenes y otro gran número de bacterias patógenas.​​
  • 溶血素あるいは溶血毒素（米: hemolysin、英: haemolysin）とは、微生物によって産生される、赤血球の細胞膜に傷害を与えることでその赤血球を破壊する脂質またはタンパク質である。微生物により分泌された溶血素による赤血球の溶解は、その微生物の栄養の獲得にとって非常に重要であると見られているが、病原体が宿主内で産生する溶血素の多くは宿主の赤血球を著しく破壊するわけではない。しかし、多くの場合、in vitroでは溶血素は赤血球を溶解させる。
  • On appelle hémolysine, une substance (le plus souvent une protéine) susceptible de causer une hémolyse, c'est-à-dire une destruction des globules rouges. Cette toxine est produite par divers organismes: des bactéries (α-hémolysine de Staphylococcus aureus) ou des champignons par exemple. En infectiologie ces toxines sont des facteurs de virulence des bactéries, aggravant les symptômes du patient. En hématologie, les hémolysines désignent des immunoglobulines dirigées contre les érythrocytes.
  • Hemolisinas são exotoxinas produzidas por bactérias que provocam lise dos eritrócitos in vitro. Visualização da hemólise em eritrócitos em placas de agar facilita a categorização de algumas bactérias patogénicas como Streptococcus.
