Abstract

Contamination of dry foods with the Cronobacter genus bacteria poses a significant challenge for ensuring microbiological safety of food products for infants and children, because these pathogens can cause severe infections in infants. We studied Cronobacter strains isolated from samples of dry infant food products sold in the Russian Federation, as well as components for their production. It was found that all the isolated strains belonged to the most epidemiologically significant Cronobacter sakazakii species, and the presence of at least four genes characterizing different virulence mechanisms was confirmed for all strains.

婴儿干食品中克罗诺杆菌属细菌的分子生物学特性研究。

克罗诺杆菌属细菌污染干食品对确保婴幼儿食品的微生物安全构成重大挑战，因为这些病原体可导致婴儿严重感染。我们研究了从俄罗斯联邦销售的干婴儿食品样品中分离出的克罗诺杆菌菌株及其生产成分。结果发现，所有分离菌株均属于最具流行病学意义的阪崎克罗诺杆菌种，且所有菌株均存在至少4个表征不同毒力机制的基因。

期刊介绍： Bulletin of Experimental Biology and Medicine presents original peer reviewed research papers and brief reports on priority new research results in physiology, biochemistry, biophysics, pharmacology, immunology, microbiology, genetics, oncology, etc. Novel trends in science are covered in new sections of the journal - Biogerontology and Human Ecology - that first appeared in 2005. World scientific interest in stem cells prompted inclusion into Bulletin of Experimental Biology and Medicine a quarterly scientific journal Cell Technologies in Biology and Medicine (a new Russian Academy of Medical Sciences publication since 2005). It publishes only original papers from the leading research institutions on molecular biology of stem and progenitor cells, stem cell as the basis of gene therapy, molecular language of cell-to-cell communication, cytokines, chemokines, growth and other factors, pilot projects on clinical use of stem and progenitor cells. The Russian Volume Year is published in English from April.
