Ruling Out Bacillus anthracis

Inhibition of Bacillus anthracis spore outgrowth by nisin.

The lantibiotic nisin has previously been reported to inhibit the outgrowth of spores from several Bacillus species. However, the mode of action of nisin responsible for outgrowth inhibition is poorly understood. By using B. anthracis Sterne 7702 as a model, nisin acted against spores with a 50% inhibitory concentration (IC(50)) and an IC(90) of 0.57 microM and 0.90 microM, respectively. Viable...

Real-Time PCR Identification of Unique Bacillus anthracis Sequences.

Bacillus anthracis is a spore-forming, Gram-positive microorganism. It is a causative agent of anthrax, a highly infectious disease. It belongs to the "Bacillus cereus group", which contains other closely related species, including Bacillus cereus, Bacillus thuringiensis, Bacillus mycoides, Bacillus weihenstephanensis, and Bacillus pseudomycoides. B. anthracis naturally occurs in soil environme...

Transduction in Bacillus cereus and Bacillus anthracis.

A phage, designated CP-51, that carries out generalized transduction in Bacillus cereus and B. anthracis, has recently been isolated from soil. Transducing phages for members of the genus Bacillus have been described previously for B. subtilis and B. licheniformis (2-6). Those that have been best characterized are PBS-1 for B. subtilis (4) and SP-10 and SP-15 for both B. subtilis and B. licheni...

Novel Giant Siphovirus from Bacillus anthracis Features Unusual Genome Characteristics

Here we present vB_BanS-Tsamsa, a novel temperate phage isolated from Bacillus anthracis, the agent responsible for anthrax infections in wildlife, livestock and humans. Tsamsa phage is a giant siphovirus (order Caudovirales), featuring a long, flexible and non-contractile tail of 440 nm (not including baseplate structure) and an isometric head of 82 nm in diameter. We induced Tsamsa phage in s...
