Colonization of the digestive tract of germ-free mice by genetically engineered strains of Lactococcus lactis: study of recombinant DNA stability.

Microbial releases : viruses, bacteria, fungi - 1 Dec 1992

Gruzza M, Duval-Iflah Y, Ducluzeau R

Abstract excerpt

The ability of genetically engineered Lactococcus lactis strains to become established in the digestive tract (DT) of germ-free mice was examined together with the stability of their genetic markers. Seven L. lactis strains were genetically modified by insertion of genetic markers on different replicons: chloramphenicol resistance gene cat was carried by self-transmissible plasmid pIL205, a derivative of plasmid...
