    Abstract This study evaluated a depot-formulated cytokine-based adjuvant to improve the efficacy of the recombinant F1V (rF1V) plague vaccine and examined the protective response following aerosol challenge in a murine model. The results of this study showed that co-formulation of the Alhydrogel-adsorbed rF1V plague fusion vaccine with the depot-formulated cytokines recombinant human interleukin 2 (rhuIL-2) and/or recombinant murine granulocyte macrophage colony-stimulating factor (rmGM-CSF) significantly enhances immunogenicity and significant protection at lower antigen doses against a lethal aerosol challenge. These results provide additional support for the co-application of the depot-formulated IL-2 and/or GM-CSF cytokines to enhance vaccine efficacy.

    Abstract DNA vaccination is vaccination at its simplest. Due to renewed interest in vaccination against anthrax and other biothreat agents, a genetic immunisation approach offers attractive possibilities for rapid, responsive vaccine development. DNA vaccination against anthrax is an active area of research showing promising results at present, which in the short-term and in the future could form the basis for new advances in multi-agent vaccine development. The anthrax 'model' constitutes an important experimental system for genetic immunisation technology development.

    Abstract A DNA encoding the 27-kDa domain I of anthrax lethal factor protein (LF), was linked to the carboxyl terminus of the cholera toxin B-subunit (CTB-LF). The CTB-LF fusion gene was transferred into Solanum tuberosum cells by Agrobacterium tumefaciens-mediated in vivo transformation methods and antibiotic-resistant plants were regenerated. The CTB-LF fusion gene was detected in transformed potato leaf genomic DNA by polymerase chain reaction (PCR)-mediated DNA amplification. Immunoblot analysis with anti-CTB and anti-LF primary antibodies verified the synthesis and assembly of biologically active CTB-LF fusion protein oligomers in transformed plant tuber tissues. Furthermore, the binding of CTB-LF fusion protein pentamers to intestinal epithelial cell membrane receptors measured by GM1-ganglioside enzyme-linked immunosorbent assay (GM1-ELISA) indicated that the CTB-LF fusion protein made up approx 0.002% of the total soluble tuber protein. Synthesis of CTB-LF monomers and their assembly into biologically active CTB-LF fusion protein pentamers in potato tuber tissues demonstrates the feasibility of using edible plants for production and delivery of adjuvanted LF protein for CTB-mediated immunostimulation of mucosal immune responses against anthrax toxin.

    Abstract Bacillus anthracis, the causative agent of anthrax, produces a tripartite toxin composed of two enzymatically active subunits, lethal factor (LF) and edema factor (EF), which, when associated with a cell-binding component, protective antigen (PA), form lethal toxin and edema toxin, respectively. In this preliminary study, we characterized the toxin-specific antibody responses observed in 17 individuals infected with cutaneous anthrax. The majority of the toxin-specific antibody responses observed following infection were directed against LF, with immunoglobulin G (IgG) detected as early as 4 days after the onset of symptoms in contrast to the later and lower EF- and PA-specific IgG responses. Unlike the case with infection, the predominant toxin-specific antibody response of those immunized with the US anthrax vaccine absorbed and UK anthrax vaccine precipitated licensed anthrax vaccines was directed against PA. We observed that the LF-specific human antibodies were, like anti-PA antibodies, able to neutralize toxin activity, suggesting the possibility that they may contribute to protection. We conclude that an antibody response to LF might be a more sensitive diagnostic marker of anthrax than to PA. The ability of human LF-specific antibodies to neutralize toxin activity supports the possible inclusion of LF in future anthrax vaccines.

    Abstract Previously two capsule-specific monoclonal antibodies (4VA5 and 3VIE5) were identified as protective against Burkholderia pseudomallei in passive transfer experiments. Panning these antibodies against evolutionary phage libraries identified reactive peptides capable of inhibiting its parent monoclonal from binding to B. pseudomallei. Mice immunized with peptide conjugated to thyroglobulin developed serum antibodies capable of recognizing the immunizing peptide of which a subset recognized exopolysaccharide in the context of whole B. pseudomallei cells. These serum antibodies recognized protease treated B. pseudomallei but not B. thailandensis suggesting that these peptides are mimotopes of the B. pseudomallei capsular exopolysaccharide. In a murine model of acute melioidosis, immunization with the mimotope of the 4VA5 binding site extended the mean time to death to 8.00 days over the 2.18 days afforded by immunization with thyroglobulin alone. This mimotope may be of use in developing an antibody response against B. pseudomallei exopolysaccharide.

    Abstract We used custom-designed resequencing arrays to generate 3.1 Mb of genomic sequence from a panel of 56 Bacillus anthracis strains. Sequence quality was shown to be very high by replication (discrepancy rate of 7.4 x 10(-7)) and by comparison to independently generated shotgun sequence (discrepancy rate < 2.5 x 10(-6)). Population genomics studies of microbial pathogens using rapid resequencing technologies such as resequencing arrays are critical for recognizing newly emerging or genetically engineered strains.

    Abstract Abstract Background Bacillus anthracis is considered to be a recently emerged clone within the Bacillus cereus sensu lato group. The B. anthracis genome sequence contains four putative lambdoid prophages. We undertook this study in order to understand whether the four prophages are unique to B. anthracis and whether they produce active phages. Results More than 300 geographically and temporally divergent isolates of B. anthracis and its near neighbors were screened by PCR for the presence of specific DNA sequences from each prophage region. Every isolate of B. anthracis screened by PCR was found to produce all four phage-specific amplicons whereas none of the non- B. anthracis isolates, produced more than one phage-specific amplicon. Excision of prophages could be detected by a PCR based assay for attP sites on extra-chromosomal phage circles and for attB sites on phage-excised chromosomes. SYBR-green real-time PCR assays indicated that prophage excision occurs at very low frequencies (2 × 10 -5 - 8 × 10 -8 /cell). Induction with mitomycin C increased the frequency of excision of one of the prophages by approximately 250 fold. All four prophages appear to be defective since, mitomycin C induced culture did not release any viable phage particle or lyse the cells or reveal any phage particle under electron microscopic examination. Conclusion The retention of all four putative prophage regions across all tested strains of B. anthracis is further evidence of the very recent emergence of this lineage and the prophage regions may be useful for differentiating the B. anthracis chromosome from that of its neighbors. All four prophages can excise at low frequencies, but are apparently defective in phage production.

    Abstract The outer membrane protein F gene (oprF) of Pseudomonas aeruginosa was recently shown by us to protect mice from P. aeruginosa chronic pulmonary infection when used as a DNA vaccine administered by three biolistic (gene gun) intradermal inoculations given at 2-week intervals. In the present study, we used two different strategies to improve the protective efficacy of the DNA vaccine. In the first strategy, mice were primed with two biolistic intradermal inoculations with the oprF vaccine and then were given a final intramuscular booster immunization containing either a synthetic peptide-keyhole limpet hemocyanin (KLH) conjugate or a chimeric influenza virus. Both the synthetic peptide conjugate and the chimeric virus contained peptide 10, a previously identified immunoprotective epitope of protein F. The second strategy involved the addition of a second outer membrane protein to the vaccine. DNA encoding a fusion protein comprised of the C-terminal half of protein F fused to OprI was administered by three biolistic intradermal inoculations. Challenge with P. aeruginosa in a chronic pulmonary infection model demonstrated that boosting with the chimeric virus (but not with peptide-KLH) or adding oprI to the DNA vaccine significantly enhanced protection as compared to that afforded by the oprF vaccine given alone. Thus, both strategies appear to augment the protection afforded by an oprF-only DNA vaccine.
