Freelancing is a way of independent earning from many projects and assignments that are available on freelancing websites. Freelance means that the worker is not bound by the policies of any company rather they are bound by the project they have been provided with.
Phage. Definition. noun, plural: phages. (1) A bacteriophage: a virus capable of infecting a bacterial cell, and may cause lysis to its host cell. (2) A suffix that means a thing that eats or devours (as macrophage). Supplement. Bacteriophages or phages have a specific affinity for bacteria.
Phage typing is a method used for detecting single strains of bacteria. It is used to trace the source of outbreaks of infections. The viruses that infect bacteria are called bacteriophages (phages for short) and some of these can only infect a single strain of bacteria. These phages are used to identify different strains of bacteria within a single species. A culture of the strain is grown in the agar and dried. A grid is drawn on the base of the petri dish to mark out different regions. Inoculation of each square of the grid is done by a different phage.
