Introduction of Transduction with its type

     This method of conjugation was first observed by Zinder and Lederberg in 1952 in Salmonella bacteria . In this method the gene  along with DNA transfer from one to another by a bacterial virus called bacteriophage.

            All the bacteriophage may not cause the breakdown of the host cell. The bacteriophage that cause the breakdown of host bacteria cell is called “virulent bacteriophage” The  bacteriophage which do not cause the breakdown of the host cell is called “temperate bacteriophage”. Depending on this ,there are two types of transduction . They are called

1)     Generalized transduction

2)     Specialized transduction
