[Bifidobacterial plasmids and their application to genetic engineering].
Representatives of Bifidobacterium genus are considered to play many important roles in intestinal homeostasis. On the other hand, their molecular biology and genetics have been poorly studied. In order to broaden our understanding of their health-promoting mechanisms, it is extremely important to possess tools to manipulate them genetically. Another challenging task is to take advantage of genetic engineering technology for designing new probiotic bifidobacteria with unique therapeutic properties. An important step in such work is to isolate and characterize small bifidobacterial plasmids, which can be applied to the construction of cloning vectors. This article presents a review of several pioneering studied devoted to bifidobacterial plasmids and genetic engineering with bifidobacteria. Trends in and prospects of molecular genetics of bifidobacteria are discussed as well.
