The large plasmid pXO1 encoding the anthrax toxin is important for the virulence of Bacillus anthracis. It is essential to cure pXO1 from B. anthracis to evaluate its role in the pathogenesis of anthrax infection. Because conventional methods for curing plasmids (e.g., curing agents or growth at elevated temperatures) can induce mutations in the host(More)
Plasmid incompatibility, which has no effect on other plasmids or chromosomal genes, can be used to cure a target plasmid. In this report, we successfully cured the plasmid pXO2 from Bacillus anthracis A16 with a newly constructed, incompatible plasmid pKSV7-oriIV and obtained a new pXO2-cured strain, designated A16PI2. This is the first time that a plasmid(More)
This paper proposes an architecture to extract fuzzy rules based on support vector machines (SVMs). Firstly, support vectors are obtained from the training data set to generate fuzzy IF-THEN rules with membership functions described in terms of kernel functions via support vector machine learning procedure. Then, a combined fuzzy rule base is created based(More)
Shigella flexneri, which is closely related to Escherichia coli, is the most common cause of the endemic form of shigellosis. In this study, 53 homomultimeric protein complexes and nine heteromultimeric protein complexes from S. flexneri 2a strain 2457T were separated and identified. Among these, three potential homomultimeric protein complexes had not been(More)
In this paper, we investigate the periodic dynamical behaviors for a class of general Cohen-Grossberg neural networks with discontinuous right-hand sides, time-varying and distributed delays. By means of retarded differential inclusions theory and the fixed point theorem of multi-valued maps, the existence of periodic solutions for the neural networks is(More)
UNLABELLED Conjugate vaccines are known to be one of the most effective and safest types of vaccines against bacterial pathogens. Previously, vaccine biosynthesis has been performed by using N-linked glycosylation systems. However, the structural specificity of these systems for sugar substrates has hindered their application. Here, we report a novel(More)

Immunoproteomics was used to screen the immunogenic spore and vegetative proteins of Bacillus anthracis vaccine strain A16R. The spore and vegetative proteins were separated by 2D gel electrophoresis and transferred to polyvinylidene difluoride membranes, and then western blotting was performed with rabbit immune serum against B.anthracis live spores.(More)
