内溶素(Endolysins)(或lysins)是由噬菌体(简称噬菌体)产生的高度进化的酶,用于消化细菌细胞壁以释放噬菌体后代。在革兰氏阳性菌中,外部添加少量纯化的重组溶素导致立即裂解,引起靶细菌的对数倍死亡。赖氨酸已成功地用于各种动物模型,以控制粘膜表面和感染组织上发现的致病性耐药细菌。它们对病原体的特异性而不干扰正常的植物群,细菌耐药性的低机会,以及它们杀死粘膜表面上的定殖病原体的能力,这是以前无法获得的能力,使它们成为耐药性不断增加的时代的理想抗感染剂。在这里,我们回顾了目前的文献显示这些酶在控制各种感染的有效性。
Endolysins (or lysins) are highly evolved enzymes produced by bacteriophage (phage for short) to digest the bacterial cell wall for phage progeny release. In Gram-positive bacteria, small quantities of purified recombinant lysin added externally results in immediate lysis causing log-fold death of the target bacterium. Lysins have been used successfully in a variety of animal models to control pathogenic antibiotic-resistant bacteria found on mucosal surfaces and infected tissues. Their specificity for the pathogen without disturbing the normal flora, the low chance of bacterial resistance, and their ability to kill colonizing pathogens on mucosal surfaces, a capacity previously unavailable, make them ideal anti-infectives in an age of mounting resistance. Here we review the current literature showing the effectiveness of these enzymes in controlling a variety of infections.
