Abstract

The present invention is directed to a process for the production of hybrid bacteria, characterized in that PA1 (a) a hybrid plasmid having only one cos site of a lambda or a lambdoid phage is produced from (1) a bacterial plasmid of not more than 21 Megadaltons and having only one cos site of a lambda or a lambdoid phage and (2) a foreign DNA fragment, PA1 (b) the resulting hybrid plasmid is packaged with the lysate of a lambda or lambdoid phage and PA1 (c) the packaging product is transduced into Escherichia coli whereby hybrid bacteria are formed.
