BACTERIUM TRUTTAe, A NEW SPECIES OF BACTERIUM PATHOGENIC TO TROUT

Iron-containing urease in a pathogenic bacterium.

Helicobacter mustelae, a gastric pathogen of ferrets, synthesizes a distinct iron-dependent urease in addition to its archetypical nickel-containing enzyme. The iron-urease is oxygen-labile, with the inactive protein exhibiting a methemerythrin-like electronic spectrum. Significantly, incubation of the oxidized protein with dithionite under anaerobic conditions leads to restoration of activity ...

Genome-wide responses of a pathogenic bacterium to its host.

Bacteria are remarkably sensitive and adaptable creatures. They are highly attuned to their environment, perceive a wide variety of cues, react using a complex set of mechanisms, and modify their composition and behavior in a sophisticated manner. Pathogenic bacteria are no exception. The benefits of a pathogenic lifestyle, e.g., replication within a host cell or persistence within the intravas...

Determining the antibacterial effect of ZnO nanoparticle against the pathogenic bacterium, Shigella dysenteriae (type 1)

The nanomaterials have important application in different field of science such as biology and pharmacology, which draws the attention of biologists towards this field of study more than before. As the worldwide mortality rate is high due to the pathogens and especially because of the bacteria associated dysenteriae and the antibacterial effect of metal nanoparticles is well known from centurie...
