The membrane insertion of colicins
FEBS Letters, 1992 Pore‐forming toxins, such as colicin A, are water‐soluble proteins that insert into lipid bilayers. The water‐soluble structure of Colicin A is known at a high resolution and this review describes the kinetic and structural steps involved in its soluble‐to‐membrane bound transformation.

Antibiotic Use in Livestock: A Driver of Resistance in Africa and the Path to Safer Alternatives
MicrobiologyOpen, Volume 14, Issue 6, December 2025.The incorporation of antibiotics into animal feeds is one of the drivers of antibiotic resistance, a global One Health challenge. To reduce the burden of antibiotic resistance, the use of alternative growth promoters and drugs must be promoted, as well as sensitization and implementation of regulations.

Study of Toxic Effect of Crud Colicin Exracted from Escherchia Coli on Viability of Immune Cells.
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017 Crude-colicin was extracted from g.coli isolated from urinary tract infection patients. Toxicity of various concentrations of crudt: colicin on the viability of immune cells [phagocytic ceUs(M0,PMN) and lymphocytes] was studied.

Antagonistic activity expressed by Shigella sonnei: identification of a putative new bacteriocin
Memorias do Instituto Oswaldo Cruz, 2013 Bacteriocins are antibacterial, proteinaceous substances that mediate microbial dynamics. Bacteriocin production is a highly disseminated property among all major lineages of bacteria, including Shigella.

The Journal of Experimental Medicine, 1962 The somatic antigen of the non-colicinogenic bacillus E. coli K235 L-OC- has been isolated, and its chemical and serological properties have been compared with those of colicine K. The antigen of the non-colicinogenic bacillus has a protein content significantly lower than that of the C+ antigen, a difference which might be related to the antibacterial

Antibiotics, 2016 Colicins are bacterial toxins produced by some Escherichia coli strains. They exhibit either enzymatic or pore-forming activity towards a very limited number of bacterial species, due to the high specificity of their reception and translocation systems ...

Evolutionary interplay between viruses and R‐loops
FEBS Letters, Volume 599, Issue 21, Page 3012-3028, November 2025.Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.
