BACKGROUND Recent use of Bacillus anthracis spores as a bioweapon has highlighted the need for a continuous monitoring system. Current monitoring systems rely on antibody-derived probes, which are not hardy enough to withstand long-term use under extreme conditions. We describe new, phage-derived probes that can be used as robust substitutes for antibodies. METHODS From a landscape phage libr...
The lung is the site of entry for Bacillus anthracis in inhalation anthrax, the deadliest form of the disease. Bacillus anthracis produces virulence toxins required for disease. Alveolar macrophages were considered the primary target of the Bacillus anthracis virulence factor lethal toxin because lethal toxin inhibits mouse macrophages through cleavage of MEK signaling pathway components, but w...
Anthrax is a fatal disease caused by strains of Bacillus anthracis. Members of this monophyletic species are non motile and are all characterized by the presence of four prophages and a nonsense mutation in the plcR regulator gene. Here we report the complete genome sequence of a Bacillus strain isolated from a chimpanzee that had died with clinical symptoms of anthrax. Unlike classic B. anthra...
A selective medium that allows for growith of Bacillus anthracis while inhibiting common contaminants and closely related sporeformers (e.g., Bacillus cereus) is described. This medium contains polymyxin, lysozyme, dLsodium ethylenediamine tetraacetate, and thallous acetate as the selective ingredients. It may also be used as a differential medium to distinguish B. anthracis from A. cereus and ...
Anthrax is an infectious disease in cattle and human beings that is caused by Bacillus anthracis. Primarily it shows itself in the respiratory, cutaneous and digestive systems. The involvement of cental nervous system is rare and is associated with a high rate of mortality. Since its identification is very important, therefore in this study the clinical and paraclinical diagnostic methods in ch...
Bacillus anthracis is a zoonotic agent causing anthrax, a notifiable disease in animals. The last anthrax outbreak among cattle in Germany occurred in April 2014 in Saxony-Anhalt. Here we report a high-quality genome sequence of the Bacillus anthracis strain 14RA5914 Dobichau isolated from the spleen of a dead cow.
Soil was collected in July 2013 at a site where a cow infected with anthrax had been the month before. Selective culturing yielded Bacillus anthracis strain Tangail-1. Here, we report the draft genome sequence of this Bacillus anthracis isolate that belongs to the canonical A.Br.001/002 clade.
The aim of this study was to evaluate the accuracy and reliability of the rapid analyte measurement platform (RAMP) for presumptive identification of Bacillus anthracis spores. Test samples consisted of serial dilutions of spore preparations of several Bacillus species, including B. anthracis, which were tested, using the RAMP Anthrax test cartridge, according to the manufacturer's instructions...
A two-component direct fluorescent-antibody (DFA) assay, using fluorescein-labeled monoclonal antibodies specific to the Bacillus anthracis cell wall (CW-DFA) and capsule (CAP-DFA) antigens, was evaluated and validated for rapid identification of B. anthracis. We analyzed 230 B. anthracis isolates; 228 and 229 were positive by CW-DFA and CAP-DFA assays, respectively. We also tested 56 non-B. an...
Bacillus anthracis is a Gram-positive, spore-forming soil bacterium that is closely related to Bacillus cereus and Bacillus thuringiensis. Infections with Bacillus anthracis result in a disease called anthrax (Mock and Fouet 2001; Sylvestre et al. 2002). Anthrax is primarily an infection of grazing cattle. Ingested spores germinate within the host to the vegetative form. Vegetative cells multip...
