A number of prokaryotic proteins have been shown to contain nuclear localization signals (NLSs), although its biological role remains sometimes unclear. Terminal proteins (TPs) of bacteriophages prime DNA replication and become covalently linked to the genome ends. We predicted NLSs within the TPs of bacteriophages from diverse families and hosts and, indeed, the TPs of Φ29, Nf, PRD1, Bam35, an...
Colibacillosis is a disease caused by Escherichia coli and remains major concern in poultry production, as it leads to significant economic losses due carcass condemnation clinical symptoms. The development of antimicrobial resistance growing problem worldwide concern. Lysogenic bacteriophages are effective vectors for acquiring disseminating antibiotic genes (ARGs). aim this study was investig...
The vaccine was first developed in 1796 by a British physician, Edward Jenner, against the smallpox virus. This invention revolutionized medical science and saved lives around world. production of effective vaccines requires dominant immune epitopes to elicit robust response. Thus, applying bacteriophages has attracted attention many researchers because their advantages design development. Bact...
Bacterial pathogens cause significant morbidity and mortality annually to both humans and animals. With the rampant spread of drug resistance and the diminishing effectiveness of current antibiotics, there is a pressing need for effective diagnostics for detection of bacterial pathogens and their drug resistances. Bacteriophages offer several unique opportunities for bacterial detection. This r...
Bacteriophages have been a model system to study assembly processes for over half a century. Formation of infectious phage particles involves specific protein-protein and protein-nucleic acid interactions, as well as large conformational changes of assembly precursors. The sequence and molecular mechanisms of phage assembly have been elucidated by a variety of methods. Differences and similarit...
Plant necrotrophic Dickeya spp. are among the top ten most devastating bacterial plant pathogens able to infect a number of different plant species worldwide including economically important crops. Little is known of the lytic bacteriophages infecting Dickeya spp. A broad host lytic bacteriophage ϕD3 belonging to the family Myoviridae and order Caudovirales has been isolated in our previous stu...
Viruses that attack bacteria – bacteriophages – can be fussy: they only inject their genetic material into the bacteria that suit them. The fussiness of bacteriophages can be exploited in order to detect specific species of bacteria. Scientists from Warsaw have just demonstrated that bacteriophage-based biosensors will be much more efficient if prior to the deposition on the surface of the bact...
Exposure of Escherichia coli MG1655 to environmental bacteriophages results in rapid selection for phage-tolerant subpopulations displaying increased biofilm formation. Analysis of one phage-tolerant strain revealed large amounts of the DNA-binding Dps protein in the outer membrane protein and production of fimbria-like structures. In dps and fimA mutant derivatives of MG1655, no selection of p...
Complex interactions between bacteriophages and their bacterial hosts play significant roles in shaping the structure of environmental microbial communities, not only by genetic transduction but also by modification of bacterial gene expression patterns. Survival of phages solely depends on their ability to infect their bacterial hosts, most importantly during phage entry. Successful dynamic ad...
Bacteriophages are viruses that infect bacteria, and consequently they have a major impact on the development of a microbial population. In this study, the genome of a novel broad host range bacteriophage, Aquamicrobium phage P14, isolated from a wastewater treatment plant, was analyzed. The Aquamicrobium phage P14 was found to infect members of different Proteobacteria classes (Alphaproteobact...
