Advanced technologies to remove organic micropollutants (OMPs) from municipal wastewater have gained much attention over the last decades. Adsorption by zeolites is one of these technologies. In this study, regeneration performance well-tailored granular loaded with OMPs was evaluated. The selected were categorized into three groups due adsorption performance: high, medium and low adsorbance. G...

The lymphogranuloma venereum (LGV) and trachoma biovars of Chlamydia trachomatis exhibit differences in biological properties both in vivo and in vitro. To identify analogous biochemical differences, we studied the molecular charges of chlamydial outer membrane proteins (OMPs) by means of isoelectric focusing and nonequilibrium pH gradient electrophoresis. Analysis of proteins of whole elementa...

Gram-negative bacteria contain a double membrane which serves for both protection and for providing nutrients for viability. The outermost of these membranes is called the outer membrane (OM), and it contains a host of fully integrated membrane proteins which serve essential functions for the cell, including nutrient uptake, cell adhesion, cell signalling and waste export. For pathogenic strain...

Francisella tularensis is a Gram-negative intracellular coccobacillus and the causative agent of the zoonotic disease tularemia. When compared with other bacterial pathogens, the extremely low infectious dose (<10 CFU), rapid disease progression, and high morbidity and mortality rates suggest that the virulent strains of Francisella encode for novel virulence factors. Surface-exposed molecules,...

BACKGROUND Leptospira interrogans is the major causative agent of leptospirosis. Phagocytosis plays important roles in the innate immune responses to L. interrogans infection, and L. interrogans can evade the killing of phagocytes. However, little is known about the adaptation of L. interrogans during this process. METHODOLOGY/PRINCIPAL FINDINGS To better understand the interaction of pathoge...

The interactions of outer membrane proteins (OMPs) with the periplasmic chaperone Skp from Escherichia coli are not well understood. We have examined the binding of Skp to various OMPs of different origin, size, and function. These were OmpA, OmpG, and YaeT (Omp85) from Escherichia coli, the translocator domain of the autotransporter NalP from Neisseria meningitides, FomA from Fusobacterium nuc...

Urinary tract infections are frequently caused by Proteus mirabilis strains. In the previous studies there were defined the complete structures of O-polysaccharide parts of lipopolysaccharides from strains: P. mirabilis O3 (S1959), P. mirabilis O9 and P. mirabilis O18. In the present study it was investigated bactericidal effect of normal human serum (NHS) to P. mirabilis strains. We also focus...

The outer membrane proteins (OMPs) of Gram-negative bacteria play a crucial role in virulence and pathogenesis. Identification of these proteins represents an important goal for bacterial proteomics, because it aids in vaccine development. Here, we have developed such an approach for Ehrlichia ruminantium, the obligate intracellular bacterium that causes heartwater. A preliminary whole proteome...

Leptospiral outer membrane proteins (OMPs) are highly conserved in different species, and play an essential role in the development of new immunoprotection and serodiagnosis strategies. The genes encoding LipL21, LipL32 and OmpL1 were cloned from the complete genome sequence of Leptospira interrogans serovar lai strain Lai and expressed in vitro. Sequence comparison analysis revealed that the t...

Since the work of Crown [5] in the 1970’s, it has been known that the projections of a finite-dimensional vector bundle E form an orthomodular poset (omp) P(E). This result lies in the intersection of a number of current topics, including the categorical quantum mechanics of Abramsky and Coecke [1], and the approach via decompositions of Harding [6]. Moreover, it provides a source of omps for t...
