Proteobactin and a yersiniabactin-related siderophore mediate iron acquisition in Proteus mirabilis

Plasmids and Putative Virulence Characters in Proteus mirabilis

Siderophore-based iron acquisition and pathogen control.

High-affinity iron acquisition is mediated by siderophore-dependent pathways in the majority of pathogenic and nonpathogenic bacteria and fungi. Considerable progress has been made in characterizing and understanding mechanisms of siderophore synthesis, secretion, iron scavenging, and siderophore-delivered iron uptake and its release. The regulation of siderophore pathways reveals multilayer ne...

Lipoprotein from Proteus mirabilis.

The biosynthesis of a Proteus mirabilis outer membrane protein of molecular weight of approximately 7,000 was found to be relatively resistant to puromycin and rifampin, as is the case for the Escherichia coli liporotein. Furthermore, the existence of the lipoprotein in P. mirabilis was indicated by a comparison of the amino acid compositions of the purified free and bound forms of this protein...

Bacteriophage typing of Proteus mirabilis, Proteus vulgaris, and Proteus morganii.

A bacteriphage typing scheme for differentiating Proteus isolated from clinical specimens was developed. Twenty-one distinct patterns of lysis were seen when 15 bacteriophages isolated on 8 Proteus mirabilis, 1 P. vulgaris, and 1 P. morganii were used to type 162 of 189 (85.7%) P. mirabilis and P. vulgaris isolates. Seven phages isolated on 3 P. morganii were used to type 13 of 19 (68.4%) P. mo...

Arthrite septique à Proteus mirabilis

Résumé L'arthrite septique aigue est une pathologie peu fréquente mais grevée d'un pronostic lourd en termes de mortalité et morbidité. Nous rapportons un cas d'arthrite septique à Proteus mirabilis survenue de façon spontanée chez un patient de 61 ansprésentant un diabète compliqué,associée à des hémoculturespositives et des cultures positives du liquide articulaire. L'évolution était favorabl...
