albomycin is an effective antibiotic, as exemplified with yersinia enterocolitica and streptococcus pneumoniae.albomycin belongs to the class of sideromycins, compounds composed of iron carriers linked to antibiotic moieties. albomycin was found to be active against bacteria that have a functional ferric hydroxamate transport system meaning that bacteria will actively transport albomycin until they die. we examined the activity spectrum of albomycin for bacterial pathogens and found that enterobacteriaceae except species of proteus and morganella were sensitive. resistance in the two genera was due to th ...200717459767
canine cathelicidin (k9cath): gene cloning, expression, and biochemical activity of a novel pro-myeloid antimicrobial peptide.cathelicidins, a group of cationic peptides found in leukocytes and epithelial cells, play a central role in the early innate immune defense against infection. although these host defense peptides have been reported in several mammalian species, including primates, no cathelicidins have been identified in carnivores. here we report the cloning, tissue expression and biological activity of a novel canine cathelicidin (k9cath). the full-length cdna sequence of k9cath encodes a predicted 172 amino ...200717462733
a novel amoeba proteus 120 kda actin-binding protein with only 1 filamin repeat and a coiled-coil region.a novel 120 kda actin-binding protein (apabp-f1) was found in amoeba proteus. it was distributed throughout the cytoplasm, mainly in the subplasma membrane and perinuclear-nuclear areas, enriched in actin. the full-length cdna of apabp consisted of 2672 nucleotides with an open reading frame of 878 amino acids, giving a ~95 kda protein with a theoretical pi value of 5.11. it had a novel domain organization pattern: the n terminus (residues 1-104) contained 1 calponin-homology (ch) domain, follow ...200717464342
efficacy of a silicone urinary catheter impregnated with chlorhexidine and triclosan against colonization with proteus mirabilis and other uropathogens.we sought to develop an infection-resistant urinary catheter. we evaluated 3 types of catheters for their efficacy against uropathogens in an in vitro model of the urinary tract. the catheter impregnated with chlorhexidine and triclosan suppressed the growth of uropathogens, including proteus mirabilis, for 20-30 days or longer.200717464922
synthesis of isomeric, oxathiolone fused chalcones, and comparison of their activity toward various microorganisms and human cancer cells line.isomeric oxathiolone fused chalcones were prepared by condensation of appropriate acetylbenzo[1,3]oxathiol-2-ones with benzaldehydes under acidic conditions. the synthesized compounds were screened for cytotoxic activity using hela cells, as well as for antibacterial activity against micrococcus luteus, staphylococcus aureus, salmonella typhimurium, escherichia coli, proteus vulgaris, antifungal activity against candida albicans, and tuberculostatic activity against mycobacterium tuberculosis h( ...200717473478
bacteriological study of pyogenic meningitis with special reference to latex agglutination.bacterial meningitis is an important and frequent devastating disease. the present study was carried out to determine the prevalence of pyogenic meningitis in our hospital in children and to find out the sensitivity of gram stain, crp and latex agglutination tests for the diagnosis of pyogenic meningitis from csf sample. out of 150 csf samples studied, 40 were diagnosed as pyogenic meningitis. h. influenzae was the commonest organism (22.5%), followed by streptococcus pneumoniae 15%, staphylococ ...200717474275
psoas abscess ten years after ipsilateral nephrectomy for pyonephrosis.pyogenic abscess of the psoas muscle is a rare disease. the authors report a recently observed case which developed 10 years after ipsilateral nephrectomy for pyonephrosis, reviewing the pertinent literature. the culture of the pus extracted only reproduced proteus mirabilis. the relation between psoas abscess and nephrectomy is unclear. to make diagnosis is important to consider this condition in differential diagnosis in presence of fever and flank tenderness in a nephrectomized patient.200717475114

co-expression of cyclin d1 and phosphorylated ribosomal s6 proteins in hemimegalencephaly.hemimegalencephaly (hmeg) is a developmental brain malformation highly associated with epilepsy. balloon cells (bcs) and cytomegalic neurons (cns) are frequently observed in hmeg specimens. cytomegaly in developmental brain malformations may reflect in aberrant activation of the mtor and beta-catenin signaling cascades, known regulators of cell size. we hypothesized that there is aberrant co-expression of phospho-ribosomal s6 (p-s6) protein, a downstream effector of the mtor cascade, as well as ...200717483958
transmission in the community of clonal proteus mirabilis carrying vim-1 metallo-beta-lactamase.several infections among patients attending our outpatient clinic were caused by imipenem-resistant proteus mirabilis that were phenotypically metallo-beta-lactamase (mbl)-positive. the aim of the study was to investigate this extrahospital dissemination and the mechanisms of resistance to carbapenems.200717491004

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
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
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
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
