Quorum Sensing Activity of Hafnia alvei Isolated from Packed Food
Quorum sensing (QS) is a mechanism adopted by bacteria to regulate expression of genes according to population density. N-acylhomoserine lactones (AHLs) are a type of QS signalling molecules commonly found in Gram-negative bacteria which have been reported to play a role in microbial spoilage of foods and pathogenesis. In this study, we isolated an AHL-producing Hafnia alvei strain (FB1) from s...
متن کاملCeftazidime resistance in Hafnia alvei.
Two morphotypes of Hafnia alvei differed in their susceptibilities to beta-lactam antibiotics. Both produced an inducible Bush group 1 beta-lactamase. Hyperinducibility of this enzyme was associated with reduced susceptibility in one morphotype.
متن کاملCharacterization of a putative 3-deoxy-D-manno-2-octulosonic acid (Kdo) transferase gene from Arabidopsis thaliana.
The structures of the pectic polysaccharide rhamnogalacturonan II (RG-II) pectin constituent are remarkably evolutionary conserved in all plant species. At least 12 different glycosyl residues are present in RG-II. Among them is the seldom eight-carbon sugar 3-deoxy-d-manno-octulosonic acid (Kdo) whose biosynthetic pathway has been shown to be conserved between plants and Gram-negative bacteria...
متن کاملComplete genome sequence of a commensal bacterium, Hafnia alvei CBA7124, isolated from human feces
BACKGROUND Members of the genus Hafnia have been isolated from the feces of mammals, birds, reptiles, and fish, as well as from soil, water, sewage, and foods. Hafnia alvei is an opportunistic pathogen that has been implicated in intestinal and extraintestinal infections in humans. However, its pathogenicity is still unclear. In this study, we isolated H. alvei from human feces and performed se...
متن کاملStructural analysis of the lipid A isolated from Hafnia alvei 32 and PCM 1192 lipopolysaccharides.
Hafnia alvei, a Gram-negative bacterium, is an opportunistic pathogen associated with mixed hospital infections, bacteremia, septicemia, and respiratory diseases. The majority of clinical symptoms of diseases caused by this bacterium have a lipopolysaccharide (LPS, endotoxin)-related origin. The lipid A structure affects the biological activity of endotoxins predominantly. Thus, the structure o...
