[A system for insertion of heterologous DNA into chromosome of group H streptococci].

A system for insertion of genes into the chromosome of group H streptococci has been elaborated. It consists of a recipient strain (Gallis GS10/1), having the fragments of lambda L-47-1 bacteriophage DNA inserted into the chromosome, and lambda 202 vector. The constructed system suggests the preliminary cloning of genes in E.
