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...

Antigen polymorphism in Borrelia hermsii, a clonal pathogenic bacterium.

The relapsing fever spirochete, Borrelia hermsii, escapes immune selection by alternating expression of surface lipoprotein alleles. The switch results from a duplicative transposition of one of several surface lipoprotein-encoding nucleotide sequences into the singular expression site. These nucleotide sequences constitute a large gene family whose diversity originated, in some cases, before t...

Antibiotic Stress Selects against Cooperation in a Pathogenic Bacterium

Ecological antagonisms such as predation, parasitism, competition, and abiotic environmental stress play key roles in shaping population biology, in particular by inducing stress responses and selecting for tolerant or resistant phenotypes. Little is known, however, about their impact on social traits, such as the production of public goods. Evolutionary trade-off theory predicts that adaptatio...

Phage-Driven Loss of Virulence in a Fish Pathogenic Bacterium

Parasites provide a selective pressure during the evolution of their hosts, and mediate a range of effects on ecological communities. Due to their short generation time, host-parasite interactions may also drive the virulence of opportunistic bacteria. This is especially relevant in systems where high densities of hosts and parasites on different trophic levels (e.g. vertebrate hosts, their bac...
