Phage Host Range and Efficiency of Platingistics of a particular bacterial virus. Because of host factors such as masking by O antigens that affects injection and the presence of restriction endonucleases, the relative efficiency of plating (EOP), that is, the titer of the phage on a given bacterial cell line compared to the maximum titer o

Bacteriophage Plaques: Theory and Analysismay be distinguished in terms of their spatial structure, i.e., the degree to which they limit diffusion, motility, and environmental mixing. Well-mixed broth, for example, represents the microbiological ideal of a non-spatially structured environment. Agar, by contrast, imposes significant limitati

If current estimates based on metagenome DNA sequence data are correct, then viruses represent the largest reservoir of unknown genetic diversity on Earth. Microscopy

These extreme environments tend to have a low biomass (typically <10. cells/ml) and low free viral abundance (10.-10.particles/ml) compared to eutrophic freshwater lakes (.) or near- shore marine environments (.). Establishing laboratory cultures from these environments pose challenges due to the

However, we have found that some bacteriophages are in a category of viruses that are not detected by any of these classical procedures. Given that th

The nucleic acid in the virus particles is then stained with a fluorescent stain and the sample viewed with an epifluorescence microscope. The method was originally developed to determine the abundance of virus particles in water samples, however the protocol has be

The flow cytometric method allows the detection and discrimination of a wide variety of viruses of different morphology, genome type, and size. The present paper describes an optimi

Classification has a predictive value and is invaluable to control experimental techniques and results. In describing viruses, the choice of methods depends on structure and taxonomical position of viruses. The study of isometric, filame
