  • Publication number: 20100266639
    Abstract: An immunogenic reagent which produces an immune response which is protective against Bacillus anthracis, said reagent comprising one or more polypeptides which together represent up to three domains of the full length Protective Antigen (PA) of B. anthracis or variants of these, and at least one of said domains comprises domain 1 or domain 4 of PA or a variant thereof. The polypeptides of the immunogenic reagent as well as full length PA are produced by expression from E. coli. High yields of polypeptide are obtained using this method. Cells, vectors and nucleic acids used in the method are also described and claimed.

  • Publication number: 20100015181
    Abstract: Spore coat-associated proteins from members of Bacillus genera, and in particular spore-coat associated protein N (CotN), have utilisation as adjuvants in vaccine formulations.

  • Patent number: 7627891
    Abstract: A prevention-based network auditing system includes a central compliance server generating network policies and configuring audits of the data communications network. The compliance server presents a graphical user interface (GUI) to describe the specific data gathering parameters, policies to be analyzed, and the schedule of analysis. One or more audit servers strategically deployed around the network employ heterogeneous data-gathering tools to gather information about the network in response to the configured audits, and transmit the gathered information to the compliance server. An audit repository stores the gathered information for use by the compliance server for security and regulatory policy assessment, network vulnerability analysis, report generation, and security improvement recommendations.

  • Patent number: 7624422
    Abstract: A prevention-based network auditing system includes an audit repository storing network information gathered by a plurality of heterogeneous information sources. A semantic normalization module identifies semantic equivalencies in the gathered information, and generates a map listing for each fact gathered by an information source, an equivalent fact or set of facts gathered by each of the other information sources. A network policy is then uniformly applied to the information that is identified as being semantically equivalent.

  • Patent number: 7536456
    Abstract: A prevention-based network auditing system includes a central compliance server storing both natural language policy documents and machine-processable policy rules in an audit repository. The compliance server provides a client-side user interface allowing a user to easily generate a machine-auditable policy by selecting/generating a natural language policy source document, and linking the applicable machine-processable policy rules to the applicable portions of the source document. The selected machine-processable policy rules are then applied to information gathered about the network during a scheduled network audit session for efficiently and systematically determining whether policy violations and/or vulnerabilities exist.
