Similarities and dissimilarities of phage genomes.
Genomic similarities and contrasts are investigated in a collection of 23 bacteriophages, including phages with temperate, lytic, and parasitic life histories, with varied sequence organizations and with different hosts and with different morphologies. Comparisons use relative abundances of di-, tri-, and tetranucleotides from entire genomes. We highlight several specific findings. (i) As previ...
متن کاملMobile effector proteins on phage genomes
Bacteriophage genomes found in a range of bacterial pathogens encode a diverse array of virulence factors ranging from superantigens or pore forming lysins to numerous exotoxins. Recent studies have uncovered an entirely new class of bacterial virulence factors, called effector proteins or effector toxins, which are encoded within phage genomes that reside among several pathovars of Escherichia...
متن کاملPhage–host interactions during pseudolysogeny
Although the study of phage infection has a long history and catalyzed much of our current understanding in bacterial genetics, molecular biology, evolution and ecology, it seems that microbiologists have only just begun to explore the intricacy of phage-host interactions. In a recent manuscript by Cenens et al. we found molecular and genetic support for pseudolysogenic development in the Salmo...
متن کاملGram-positive phage-host interactions
Bacteriophage research has seen many peaks and troughs over the past century ascending with phage therapy and application in the early 1900’s; a research peak which was largely overshadowed by the dawning of the antibiotic era, and which has now deservedly regained attention as an approach against the problematic rise in antibiotic-resistant pathogenic bacteria. Following this initial scientifi...
متن کاملNongenetic Individuality in the Host–Phage Interaction
Isogenic bacteria can exhibit a range of phenotypes, even in homogeneous environmental conditions. Such nongenetic individuality has been observed in a wide range of biological processes, including differentiation and stress response. A striking example is the heterogeneous response of bacteria to antibiotics, whereby a small fraction of drug-sensitive bacteria can persist under extensive antib...
