Potential virulence factors of Proteus bacilli.
TLDR
The genus Proteus, which contains bacteria considered now to belong to the opportunistic pathogens, has its most characteristic attribute, swarming growth, enabling them to colonize and survive in higher organisms.Abstract:
The object of this review is the genus Proteus, which contains bacteria considered now to belong to the opportunistic pathogens. Widely distributed in nature (in soil, water, and sewage), Proteus species play a significant ecological role. When present in the niches of higher macroorganisms, these species are able to evoke pathological events in different regions of the human body. The invaders (Proteus mirabilis, P. vulgaris, and P. penneri) have numerous factors including fimbriae, flagella, outer membrane proteins, lipopolysaccharide, capsule antigen, urease, immunoglobulin A proteases, hemolysins, amino acid deaminases, and, finally, the most characteristic attribute of Proteus, swarming growth, enabling them to colonize and survive in higher organisms. All these features and factors are described and commented on in detail. The questions important for future investigation of these facultatively pathogenic microorganisms are also discussed.read more

Structure of the O-polysaccharide of Proteus mirabilis CCUG 10705 (OF) containing an amide of D-galacturonic acid with L-alanine.

TL;DR: The structure of the O-polysaccharide of Proteus mirabilis CCUG 10705 (OF) was determined by chemical analyses along with one- and two-dimensional (1)H and (13)C NMR spectroscopy and based on the uniqueness of the NMR structure and serological data, it was suggested to classify P. mirabilIS OF into a new separate ProteUS serogroup, O74.

Ambroxol blocks swarming and swimming motilities and inhibits biofilm formation by Proteus mirabilis isolated from diabetic foot infection
TL;DR: It is suggested that ambroxol could be used for the treatment of Proteus mirabilis diabetic foot infections due to its ability to interfere with swarming and invasion of tissues in addition to inhibition of biofilm formation and removal of established biofilms.

The inhibitory and stimulatory behavior for some of chemical compounds and watery extract of black tea and Arabian coffee on the swarming phenomenon of clinical isolates of Proteus mirabilis.
TL;DR: The extent of swarming differed according to tested chemical compounds, their concentration and the bacterial strains, and most of the compounds that inhibited swarming were those acted on flagellar mechanism and motility.

Molecular basis of bacterial outer membrane permeability.

TL;DR: It is becoming increasingly clear that the outer membrane is very important in the physiology of gram-negative bacteria in making them resistant to host defense factors such as lysozyme, P-lysin, and various leukocyte proteins.

Agents that increase the permeability of the outer membrane.
TL;DR: Chelators (such as EDTA, nitrilotriacetic acid, and sodium hexametaphosphate), which disintegrate the outer membrane by removing Mg2+ and Ca2+, are effective and valuable permeabilizers.

TL;DR: The biological analysis of synthetic lipid A partial structures proved that the expression of endotoxic activity depends on a unique primary structure and a peculiar endotoxic conformation, and molecular and submolecular details of the specificity of the interaction of lipid A with responsive host cells are determined.

Molecular biology of microbial ureases.
TL;DR: The crystal structure of the K. aerogenes enzyme has been determined and provides important insight into the mechanism of catalysis, and accessory genes have been shown to be required for activation of urease apoprotein, and roles for the accessory proteins in metallocenter assembly have been proposed.
