Bacteria, Phages and Septicemia
The use of phages is an attractive option to battle antibiotic resistant bacteria in certain bacterial infections, but the role of phage ecology in bacterial infections is obscure. Here we surveyed the phage ecology in septicemia, the most severe type of bacterial infection. We observed that the majority of the bacterial isolates from septicemia patients spontaneously secreted phages active aga...
متن کاملCommunication Among Phages, Bacteria, and Soil Environments
Bacteriophages (phages) are viruses that infect members of domain Bacteria, contrasting the viruses of domains Archaea or Eukarya. Ecology is the interaction of organisms with environments, and those interactions, broadly speaking, may be depicted as forms of communication – the movement of information between or among entities, or at least the presentation of potentially detectable signals. Re...
متن کاملPersistence of bacteria and phages in a chemostat.
The model of bacteriophage predation on bacteria in a chemostat formulated by Levin et al. (Am Nat 111:3-24, 1977) is generalized to include a distributed latent period, distributed viral progeny release from infected bacteria, unproductive adsorption of phages to infected cells, and possible nutrient uptake by infected cells. Indeed, two formulations of the model are given: a system of delay d...
متن کاملBattling Phages: How Bacteria Defend against Viral Attack
Bacteriophages (phages) are accomplished, bacteria-specific, viral predators with far-reaching impact: from the food and biotechnology industries [1] to global nutrient cycling [2] to human health and disease [3]; wherever bacteria thrive, it seems, so do predatory phages. In order to survive the constant onslaught of phage, bacteria have evolved mechanistically diverse defense strategies that ...
متن کاملCurrent taxonomy of phages infecting lactic acid bacteria
Phages infecting lactic acid bacteria have been the focus of significant research attention over the past three decades. Through the isolation and characterization of hundreds of phage isolates, it has been possible to classify phages of the dairy starter and adjunct bacteria Lactococus lactis, Streptococcus thermophilus, Leuconostoc spp., and Lactobacillus spp. Among these, phages of L. lactis...
