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

Comparison of PCR-based molecular markers for the characterization of Proteus mirabilis clinical isolates
Lessandra Michelim,Gabriela Müller,Jucimar Zacaria,Ana Paula Longaray Delamare,Sérgio Olavo Pinto da Costa,Sergio Echeverrigaray +5 more
TL;DR: It is concluded that a combination of ERIC-PCR and BOX- PCR results is a rapid and reliable alternative for discrimination among P. mirabilis clinical isolates, contributing to epidemiological studies.

Dependence of swarming in Escherichia coli K-12 on spermidine and the spermidine importer
TL;DR: It is reported that the swarming phenotype of a polyamine-deficient E. coli strain is dependent on spermidine and PotABCD, a sperMidine importer.

Genotypic and phenotypic profiles of virulence factors and antimicrobial resistance of Proteus mirabilis isolated from chicken carcasses: potential zoonotic risk
Matheus Silva Sanches,Ana Angelita Sampaio Baptista,Marielen de Souza,Maísa Fabiana Menck-Costa,Vanessa Lumi Koga,Renata Katsuko Takayama Kobayashi,Sérgio Paulo Dejato da Rocha +6 more
TL;DR: Genotypic and phenotypic characteristics of the virulence factors and antimicrobial resistance determinants of 32 P. mirabilis strains isolated from chicken carcasses in a poultry slaughterhouse in the north of the state of Paraná, Brazil, are evaluated in order to assess a potential zoonotic risk.
Journal ArticleDOI
The binding of Proteus mirabilis nonagglutinating fimbriae to ganglio-series asialoglycolipids and lactosyl ceramide.
TL;DR: The results of this study suggest that NAF of P. mirabilis recognize a GalNAc beta 1-4Gal moiety present in the ganglio-series of asialoglycolipids, and that the terminal beta-galactopyranosyl-containing glycoconjugates play a role in NAF-mediated adherence of P.'s mirabilIS to MDCK cells.

Molecular basis of bacterial outer membrane permeability.
Hiroshi Nikaido,Martti Vaara +1 more
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.
Journal ArticleDOI
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.

Virulence factors in Escherichia coli urinary tract infection.
TL;DR: This review summarizes the virtual explosion of information regarding the epidemiology, biochemistry, mechanisms of action, and genetic basis of these urovirulence factors that has occurred in the past decade and identifies areas in need of further study.
Journal ArticleDOI
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.
