The Covalent Rigid-Layer Lipoprotein in Cell Walls of Proteus mirabilis

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...

Plasmids and Putative Virulence Characters in Proteus mirabilis

Fimbriae of uropathogenic Proteus mirabilis.

Proteus mirabilis is a common causative agent of cystitis and pyelonephritis in patients with urinary catheters or structural abnormalities of the urinary tract. Several types of fimbriae, which are potentially involved in adhesion to the uroepithelium, can be expressed simultaneously by P. mirabilis: mannose-resistant/Proteus-like (MR/P) fimbriae, P. mirabilis fimbriae (PMF), uroepithelial cel...

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...
