From the Latin lysis, from the Ancient Greek λύσις ("a loosening"); compare -lysis.


  • Lysostaphin works by first attaching itself to the bacterial cell wall and then slicing open the cell wall (the enzyme's name derives from the Greek "lysis" meaning "to loosen or release").


  • To study viral infections, Weitz teamed with postdoctoral fellow Yuriy Mileyko, graduate student Richard Joh and Eberhard Voit, who is a professor in the Wallace H. Coulter Department of Biomedical Engineering, the David D. Flanagan Chair Georgia Research Alliance Eminent Scholar in Biological Systems and director of the new Integrative BioSystems Institute at Georgia Tech. Nearly all previous theoretical studies have claimed that switching between "lysis" and


  • Daptomycin exerts bactericidal activity without lysis of Staphylococcus aureus.


  • For example, the dissolved organic matter absorbed by a bacterium is likely a mixture of that excreted by a primary producer and some from the viral lysis of another bacterium as well the excreta of yet another organism that fed on a herbivore or a primary producer.

    Marine microbes

  • From observations in lab studies, it appears that these cyanophage-encoded photosynthesis genes force the infected host cell to continue with photosynthesis until shortly before cell lysis.

    Marine viruses

  • Lytic (or virulent) viruses infect a cell (or tissue), replicate (i.e. make new viruses) and are released by lysis the host cell.

    Marine viruses

  • In this scenario, once a microbe becomes dominant, the increase in abundance increases its contacts with viruses leading to significant increases in infection and subsequent lysis, which then control its abundance.

    Marine viruses

  • These organically-complexed nutrients released to the marine community during virus lysis therefore need to be assimilated into cells by different biochemical pathways than those released during the remineralization of organic material.

    Marine viruses

  • The bacterial culture is concentrated by centrifugation and disrupted by lysis with an alkaline detergent solution containing enzymes to degrade contaminating RNA.
