[A system for insertion of heterologous DNA into chromosome of group H streptococci]. / Sistema dlia vvedeniia geterologichnykh DNK v khromosomu streptokokkov gruppy H.

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. coli cells with their subsequent insertion into the chromosome of group H streptococci.
