Document Summary
This is a survey done in a river. Its looking at vibrio cholera levels in the river, and they also looked at cholera cases at a nearby hospital. When theres high levels of phages in the river, cholera levels are low and hospital cholera cases are low. When the phages are lower, theres more cholera cases. Temperate pjages can be lytic or lysogenic where they merge their genomes into the bacterial genomes so they can remain dormant for a period of time. The first stage is adsorption where the tail contacts the cells surface. The tail has proteins that recognize specific molecules on the cell surface. Phages tend to be specific even within specific strains of a species. This specificity is determined by the recognizition molecules on the phages tail, and once it gets attached, the dna comes out of the head and into the cell.
