Unlike lytic phages, temperate phages that enter lysogeny maintain a long-term association
with their bacterial host. In this context, mutually beneficial interactions can evolve that …

Molecular genetic research on bacteriophage lambda carried out during its golden age from
the mid-1950s to mid-1980s was critically important in the attainment of our current …

Phages are the most abundant entity in the biosphere and outnumber bacteria by a factor of
10. Phage DNA may also constitute 20% of bacterial genomes; however, its role is ill …

Bacteriophages and genetic elements, such as prophage-like elements, pathogenicity
islands, and phage morons, make up a considerable amount of bacterial genomes. Their …

The lysis-lysogeny decision of bacteriophage lambda (λ) is a paradigm for developmental
genetic networks. There are three key features, which characterize the network. First, after …

Shiga toxins (Stx) of Shiga toxin-producing Escherichia coli (STEC) are generally encoded
in the genome of lambdoid bacteriophages, which spend the most time of their life cycle …

In this article we explain how current events in the field of phage therapy may positively
influence its future development. We discuss the shift in position of the authorities …

Aphids maintain mutualistic symbioses involving consortia of coinherited organisms. All
possess a primary endosymbiont, Buchnera, which compensates for dietary deficiencies; …

Shiga toxins are the main virulence factors of a group of Escherichia coli strains [Shiga toxin-
producing E. coli (STEC)] that cause severe human diseases, such as haemorrhagic colitis …

The bacterial SOS response represents a paradigm of gene networks controlled by a master
transcriptional regulator. Self-cleavage of the SOS repressor LexA induces a wide range of …
