Bacteriophages biological studies

Viruses are classified initially on the basis of the hosts they infect. Thus we have animal viruses, plant viruses, and bacterial viruses. Bacterial viruses, sometimes called bacteriophages (or phage for short, from the Greek phago meaning to eat), have been studied primarily as convenient model systems for research on the molecular biology and genetics of virus reproduction. Many of the basic concepts of... [Pg.107]

While it is easy to visualize the assembly of oligomeric proteins, it is not as easy to imagine how complex objects such as eukaryotic cilia (Fig. 1-8) or the sarcomeres of muscle (Fig. 19-6) are formed. However, study of the assembly of bacteriophage particles and other small biological objects has led to the concepts of self-assembly and assembly pathways, concepts that are now applied to every aspect of the architecture of cells. [Pg.362]

Puck and others used the theories of colloid stability to explain the adsorption of bacteriophage by bacteria. Their findings appeared to be compatible with those of the basic colloid theory. This work and that of Valentine and Allison " led to the novel result that initial contact between virus particles and bacterial surfaces was regulated by electrostatic repulsion and the forces that govern the double layer. While these early studies were not as successful as one might have wished, they did show a correlation between the DLVO theory and the experimental data. Though the evidence is not conclusive, the work by Curtis and Pethica also tends to show that the DLVO theory is relevant to some biological systems. Other studies done at the time tended to show little or no correlation between the DLVO theory... [Pg.118]
