susceptibility of human pathogenic bacteria to antimicrobial peptides from sesame infection caused by gram-negative bacteria is a serious and common problem, especially in developing countries. aiming to reduce these infections, this report focuses on the identification and characterization of novel antimicrobial peptides from sesame (sesamum indicum) kernel meals. thus, sesame flour was extracted and precipitated with ammonium sulfate (100%). after dialysis, a rich fraction was applied to affinity red-sepharose cl-6b chromatography, followed by reversed-phase high-p ...200717570014
bone malformations in proteus syndrome: an analysis of bone structural changes and their evolution during growth.the radiographic follow-up of a patient with proteus syndrome is presented. review of radiographs obtained at 3 years 10 months, 10 years, and 17 years 8 months indicated that the rate of growth in length of the oversized tubular bones of the hands was similar to that of the normal bones of the same hand. this observation supports the view that the primary lesion occurs in the early embryonic period, when the limb bud mesenchyme cells condense and cartilage differentiates producing oversized car ...200717569038

rheumatoid arthritis patients have elevated antibodies to cross-reactive and non cross-reactive antigens from proteus microbes.although a large number of independent studies have shown a paramount role for proteus mirabilis in the aetiopathogenesis of rheumatoid arthritis (ra), this hypothesis is still controversial among rheumatologists. the main obstacle to its acceptance is the impression that increased proteus antibodies in ra patients is a secondary phenomenon, occurring as the result of cross-reactivity between bacterial and self-antigens. to shed light on this problem, we examined the link between antibodies to v ...200717543151
efficacy of ertapenem in the treatment of early ventilator-associated pneumonia caused by extended-spectrum beta-lactamase-producing organisms in an intensive care unit.ventilator-associated pneumonia (vap) is a frequent complication of patients admitted to intensive care units (icus). ertapenem is a newer carbapenem with good in vitro activity against extended-spectrum beta-lactamase (esbl)-producing organisms. however, there are no clinical data to support the use of ertapenem in vap. our purpose is to evaluate the usefulness and safety of ertapenem in the treatment of vap caused by susceptible esbl strains.200717540673
intranasal immunisation with recombinant lactococcus lactis displaying either anchored or secreted forms of proteus mirabilis mrpa fimbrial protein confers specific immune response and induces a significant reduction of kidney bacterial colonisation in mice.proteus mirabilis, a common cause of urinary tract infections in humans, can express different fimbriae. mr/p fimbriae may contribute to bacterial colonisation, and its structural protein mrpa represents a promising candidate antigen for mucosal vaccination. commercial complex vaccines have limited, short-lived protection and are incapable of eliciting mucosal responses against putative antigens related to virulence. the development of mucosal live vaccines using food-grade lactic acid bacterium ...200717540603
a comparative assessment of the antimicrobial effects of garlic (allium sativum) and antibiotics on diarrheagenic organisms.antimicrobial sensitivity tests were carried out on escherichia coli, shigella sp, salmonella sp, and proteus mirabilis using standard procedures. significant differences (p < 0.01) were seen in the effect of the antimicrobial agents (garlic, ciprofloxacin and ampicillin), and in the sensitivities of the microbial species (p < 0.01) to the antimicrobial agents were observed. the gram-negative diarrheagenic pathogens from the stool samples were highly sensitive to garlic, while ciprofloxacin (cpx ...200717539285
