A study on the mechanism of causing the disease of Enterobacter (Cronobacter) sakazakii a food oriented pathogenic bacterium
A study on the mechanism of causing the disease of Enterobacter (Cronobacter) sakazakii a food oriented pathogenic bacterium Test host Test Purpose and Contents Cronobacter spp. is a food oriented pathogenic bacterium which is oriented mainly from baby food and causes necrotizing enterocolitis, a local infection in infant of age 1 or less and meningoencephalitis a systemic infection.
Present major research subjects are 1) to reclassify the bacteria separated by Enterobacter sakazakii into Cronobacter spp. a new naming system through biochemical test and genetic analysis, ii) search for virulence factors involved in intestinal phase and endothelial infection when Cronobacter spp, enters blood circulation through intestinal tract and seek for more in-depth study on them. -
Control of food oriented pathogenic bacterium using bacteriophage
Control of food oriented pathogenic bacterium using bacteriophage Test host Test Purpose and Contents Bacteriophage is a bacterium virus that infects and kills only bacteria. As self-replicating units existing in the greatest number on the earth, bacteriophages are estimated to exist 10 times to 100 times compared to microorganism in number.
Such phages are limited in species or genus level and have peculiarities that are not found in other anti-microbial agents, ensuring safety, so they are getting spotlight as new bacteria control substance. In particular, as the U.S. FDA assigned the status of GRAS(generally regarded as safe) to anti-listeria phage, it is increasingly getting interest. In this field, researches are focusing efforts to analyze the characteristics of bacteriophage that can control only particular pathogenic bacterium by separating it from various foods and applying it to real daily life. -
A study on the effects of temperate bacteriophage on the pathogenicity and stress resistance
A study on the effects of temperate bacteriophage on the pathogenicity and stress resistance Test host Test Purpose and Contents Temperate bacteriophage is a bacteriophage that exists as part of bacteria genome and multiplies simultaneously when host bacteria multiply. The genes that such bacteriophages encode affect various characteristics of bacteria through lysogenic conversion, and major examples include production of bacterial toxic substance, pathogenicity of bacteria and stress resistance.
This research is about separation of temperate phages existing in Cronobacter spp, and their role in the pathogenicity of bacteria and stress resistance.
