Phylogenetic analysis of Escherichia coli strains isolated from human samples
Escherichia coli (E. coli) is a normal inhabitant of the gastrointestinal tract of vertebrates, including humans. Phylogenetic analysis has shown that E. coli is composed of four main phylogenetic groups (A, B1, B2 and D). Group A and B1 are generally associated with commensals, whereas group B2 is associated with extra-intestinal pathotypes. Most enteropathogenic isolates, however, are assigne...
متن کاملOptimization of Cloning Conditions for high-level Production of Recombinant Mouse Interleukin-2 in Escherichia coli
Backgrounds and objectives: Interleukin 2 (IL-2) secreted by activated CD4+ T cells has been known as a major mediator in both adaptive and native immune system due to a board range of effects on different cells in the immunity system (1-6). Methods: cDNA synthesis was performed using gene- specific primers designed by Gene Runner software after RNA extraction of mouse splenocytes. PCR pro...
متن کاملCharacterization of human and mouse granulocyte-macrophage-colony-stimulating factors derived from Escherichia coli.
Human and mouse granulocyte-macrophage-colony-stimulating factors (hGM-CSF and mGM-CSF, respectively), isolated from Escherichia coli cells expressing the corresponding human and mouse genes, have been characterized. The observed properties of the proteins have been compared with those properties which can be deduced from the DNA sequence alone and the published properties of natural GM-CSFs. T...
متن کاملExtended Characterization of Human Uropathogenic Escherichia coli Isolates from Slovenia
Escherichia coli (E. coli) is a very diverse bacterial species found naturally in the intestinal tract of humans and many other animal species. Even though E. coli is known to be part of the normal gut microbiota, some strains – that are pathogenic – cause a wide variety of different intestinal and extraintestinal diseases (Marrs et al., 2005). Typical extraintestinal infections due to E. coli ...
متن کاملPURIFICATION AND CHARACTERIZATION OF THE CLONED HUMAN GM-CSF GENE EXPRESSED IN ESCHERICHIA COLI
The human granulocyte-macrophage colony stimulation factor (hGM-CSF) gene was cloned in the pET 23a( +) expression vector under the control of strong bacteriophage T7 transcription and translation signals. The hGM-CSF gene was transferred into E. coli strainBL21 (DE3)pLysS andIPTG was used for induction of GM-CSF gene. Production of the target protein was obtained as revealed by ELISA and ...
