After induction, Stx1-converting phage Lys8385Vzw and Stx2-converting phage Lys12581Vzw were isolated and further confirmed for the presence of stx genes ... WebThese are only examples: PCD induction in response to lytic phage growth seems to be a common strategy of altruistic defense in bacteria. From the perspective of temperate phages, lysogeny is an “escape” mechanism from these defense systems allowing the phage to co-reproduce with the host.

WebIntegration of prophages into the bacterial host is the characteristic step of the lysogenic cycle of temperate phages. Prophages remain latent in the genome through multiple cell divisions until activation by an external factor, such as UV light, leading to production of new phage particles that will lyse the cell and spread. WebFor example, 40 out of 148 Lactobacilli strains, representing 15 species, released phage particles upon mitomycin induction. In particular, 77% of 30 L. Salivarius produced temperate phages, killer particles or defective phages. Temperate prophages were found in 10% of 105 strains of L. bulgaricus and L. lactis (Sechaud et al., 1988).
