Web8 aug. 2024 · Prophages are latent temperate phages that are most often stably integrated into the host bacterium’s genome, where they replicate passively as DNA during cell division. Phage development occurs in the lytic cycle following host cell infection or prophage induction from the lysogenic cycle ( Fig 1 ). 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).
