Haploid biotechnology as a tool for creating a selection material for sugar beets.

Since the discovery of the phenomenon of haploidy, biotechnology has become an integral part in the successful creation of new varieties and hybrids of various plant species. In particular, these technologies are actively used in agriculture, which is concerned with increasing the volume and improving the quality of products. The integration of haploid production techniques together with other available biotechnological tools such as marker selection (MAS), induced mutagenesis and genetic engineering technologies can significantly accelerate crop breeding.

[Sensitivity of corynebacterium diphtheriae strains to antibacterial preparations].

Aim: Study the prevalence and mechanisms of resistance in circulating C. diphtheriae strains.

Materials And Methods: 664 C.

[Multilocus sequencing of Corynebacterium diphtheriae strains isolated in Russia in 2002 - 2012].

Aim: Characterization of contemporary C. diphtheriae strains isolated in Russia by using multilocus DNA sequencing (MLST).

Materials And Methods: 28 toxigenic C.

Molecular genetic study of species and strain variability in bifidobacteria population in intestinal microflora of breast-fed infants and their mothers.

Qualitative and quantitative composition of enteric bifidoflora was studied in a group of 13 mother-infant pairs. Pure cultures of Bifidobacterium strains were isolated from feces and their species were identified by PCR with species-specific primers or by partial sequencing of 16S rDNA. The strains were compared by REP-PCR.

[Microbial colonization and succession in the large intestine of newborn infants during their stay with mothers at the maternity hospital].

Formation of microflora in the large intestine of 5-day old infants was studied in one of the Moscow maternity homes. The up-to-date procedures for isolation and identification of aerobic and anaerobic organisms were used in the study and the findings were processed on a computer. In the newborns of the maternity home of the "mother-infant" type there was observed colonization of the large intestine with aerobic and anaerobic organisms.
