Uropathogenic Escherichia coli (UPEC) strain 536 (O6:K15:H31) is one of the model organisms of extraintestinal pathogenic E. coli (ExPEC). To analyze this strain's genetic basis of urovirulence, we sequenced the entire genome and compared the data with the genome sequence of UPEC strain CFT073 (O6:K2:H1) and to the available genomes of nonpathogenic E. coli(More)
This paper is a survey of location-routing: a relatively new branch of locational analysis that takes into account vehicle routing aspects. We propose a classification scheme and look at a number of problem variants. Both exact and heuristic algorithms are investigated. Finally, some suggestions for future research are presented.
For the uropathogenic Escherichia coli strain 536 (O6:K15:H31), the DNA sequences of three pathogenicity islands (PAIs) (PAI I(536) to PAI III(536)) and their flanking regions (about 270 kb) were determined to further characterize the virulence potential of this strain. PAI I(536) to PAI III(536) exhibit features typical of PAIs, such as (i) association(More)
Role of endoplasmic reticulum (ER) in liver injury by acetaminophen (AAP) was studied in vivo in mice. Sublethal dose of AAP resulted in a decrease in microsomal total glutathione and in the reduced-to-total glutathione ratio; redox state of thiols of ER resident oxidoreductases ERp72, PDI was shifted towards the oxidized form; ER stress-responsive(More)
Yersinia pestis, the etiologic agent of plague is a highly invasive organism being able to invade non-phagocytic epithelial cells. Its plasminogen activator (Pla), encoded by the pPCP1 plasmid plays a pivotal role in internalisation of bacteria by HeLa cells. The aim of this study was to analyse the intracellular signalling processes and cytoskeletal(More)
Efficacious vaccination needs to confer protection against the vast majority of pathogens capable of causing a particular disease. Development of such vaccines is hindered by the great variability of microbes. Most pathogens have evolved variants that are able to express non-uniform surface structures. Naturally, evolutionary pressure has selected the most(More)
It has been recently shown that acute acetaminophen toxicity results in endoplasmic reticulum redox stress and an increase in cells with apoptotic phenotype in liver. Since activation of effector caspases was absent, the relevance of caspase-independent mechanisms in acetaminophen-induced programmed cell death was investigated. BGP-15, a drug with known(More)
