| role of nitric oxide in the enhancement of pentylenetetrazole-induced seizures caused by shigella dysenteriae. | convulsions and encephalopathy are frequent complications of childhood shigellosis. we studied the role of nitric oxide (no) in shigella-related seizures in an animal model. pretreatment of mice with shigella dysenteriae 60r sonicate elevated serum no levels and enhanced the convulsive response to pentylenetetrazole (ptz), as indicated by a higher mean convulsion score and a higher number of mice responding with seizures. treatment of the mice with s-methylisothiourea sulfate (smt), a potent inh ... | 1999 | 10569751 |
| activation of src family kinase yes induced by shiga toxin binding to globotriaosyl ceramide (gb3/cd77) in low density, detergent-insoluble microdomains. | shiga toxin (stx) is an enterotoxin produced by shigella dysenteriae serotype 1 and enterohemorrhagic escherichia coli, which binds specifically to globotriaosylceramide, gb3, on the cell surface and causes cell death. we previously demonstrated that stx induced apoptosis in human renal tubular cell line achn cells (taguchi, t., uchida, h., kiyokawa, n., mori, t., sato, n., horie, h., takeda, t and fujimoto, j. (1998) kidney int. 53, 1681-1688). to study the early signal transduction after stx a ... | 1999 | 10575015 |

| spontaneous tandem amplification and deletion of the shiga toxin operon in shigella dysenteriae 1. | only one species of shigella, shigella dysenteriae 1, has been demonstrated to produce shiga toxin (stx). stx is closely related to the toxins produced by shiga toxin-producing escherichia coli (stec). in stec, these toxins are often encoded on lambdoid bacteriophages and are major virulence factors for these organisms. although the bacteriophage-encoded stx genes of stec are highly mobile, the stx genes in s. dysenteriae 1 have been believed to be chromosomally encoded and not transmissible. we ... | 1999 | 10594830 |
| promiscuous origin of a chimeric sequence in the escherichia coli o157:h7 genome. | a novel sequence of 2.9 kb in the intergenic region between the muts and rpos genes of escherichia coli o157:h7 and closely related strains replaces a sequence of 6.1 kb in e. coli k-12 strains. at the same locus in shigella dysenteriae type 1, a sequence identical to that in o157:h7 is bounded by the is1 insertion sequence element. extensive polymorphism in the muts-rpos chromosomal region is indicative of horizontal transfer events. | 1999 | 10601221 |
| central nervous system manifestations of childhood shigellosis: prevalence, risk factors, and outcome. | alterations in consciousness, including seizures, delirium, and coma, are known to occur during shigella infection. previous reports have suggested that febrile convulsions and altered consciousness are more common during shigellosis than with other childhood infections. those reports, however, have been from locations where s dysenteriae type 1 was not common, thus making it difficult to assess the specific contribution that s dysenteriae type 1 infection, and shiga toxin, might make to the pat ... | 1999 | 9925864 |
| protein conjugates of synthetic saccharides elicit higher levels of serum igg lipopolysaccharide antibodies in mice than do those of the o-specific polysaccharide from shigella dysenteriae type 1. | our development of vaccines to prevent shigellosis is based on the hypothesis that a critical (protective) level of serum igg to the o-specific polysaccharide (o-sp) domain of shigella lipopolysaccharide (lps) confers immunity. the o-sp is a hapten and must be conjugated to a protein to induce serum antibodies. the o-sp of shigella dysenteriae type 1 (approximately 27 tetrasaccharide repeat units), prepared by acid hydrolysis of the lps, was bound to human serum albumin (hsa) by multiple point a ... | 1999 | 10220442 |
| an epidemic of bloody diarrhea: escherichia coli o157 emerging in cameroon? | between november 1997 and april 20, 1998, bloody diarrhea sickened 298 persons in cameroon. laboratory investigation of the epidemic (case-fatality rate, 16.4%) documented amoebiasis in one of three patients and three types of pathogens: multidrug-resistant shigella dysenteriae type 1, s. boydii, and enterohemorrhagic escherichia coli. we report the first isolation of e. coli o157:h7 in cameroon and the second series of cases in the central african region. | 1999 | 10221885 |
| lethality of a heat- and phosphate-catalyzed glucose by-product to escherichia coli o157:h7 and partial protection conferred by the rpos regulon. | a by-product of glucose produced during sterilization (121 degrees c, 15 lb/in2, 15 min) at neutral ph and in the presence of phosphate (i.e., phosphate-buffered saline) was bactericidal to escherichia coli o157:h7 (atcc 43895). other six-carbon (fructose and galactose) and five-carbon (arabinose, ribose, and xylose) reducing sugars also produced a toxic by-product under the same conditions. fructose and the five-carbon sugars yielded the most bactericidal activity. glucose concentrations of 1% ... | 1999 | 10347019 |
| shiga/verocytotoxins and shiga/verotoxigenic escherichia coli in animals. | vero/shiga toxins (vt/stx) have an a-b structure: the a subunit carries the enzymatic activity and the b subunit binds the toxin to the membrane receptor (gb3 or gb4). the vt/stx inhibit protein synthesis in the target eucaryotic cells, mainly the endothelial cells of blood vessels. the vt/stx are subdivided into two families. vt1/stx1 is a homogeneous family of toxins identical to the stx of shigella dysenteriae. vt2/stx2 is a more heterogeneous family of toxins more distantly related to this s ... | 1999 | 10367357 |

| the aerobactin iron transport system genes in shigella flexneri are present within a pathogenicity island. | genes encoding the synthesis and transport of aerobactin, a hydroxamate siderophore associated with increased virulence of enteric bacteria, were mapped within a pathogenicity island in shigella flexneri. the island, designated shi-2 for shigella pathogenicity island 2, was located downstream of selc, the site of insertion of pathogenicity islands in several other enteric pathogens. dna sequence analysis revealed the presence of multiple insertion sequences upstream and downstream of the aerobac ... | 1999 | 10411724 |
| molecular characterization of the shv-11 beta-lactamase of shigella dysenteriae. | a beta-lactamase with an m(r) of 29,000 and a pi of 7.6 was partially purified from a clinical isolate of shigella dysenteriae. the bla gene encoded the shv-11 enzyme carrying the substitution leu-->gln at position 35 and was linked to a strong promoter. this variant, unlike the prototype shv-1 enzyme, hydrolyzed oxacillin, cloxacillin, and oxyiminocephalosporins such as cefotaxime. | 1999 | 10428943 |
| i-ceui fragment analysis of the shigella species: evidence for large-scale chromosome rearrangement in s. dysenteriae and s. flexneri. | i-ceui fragments of four shigella species were analyzed to investigate their taxonomic distance from escherichia coli and to collect substantiated evidence of their genetic relatedness because their ribosomal rna sequences and similarity values of their chromosomal dna/dna hybridization had proved their taxonomic identity. i-ceui digestion of genomic dnas yielded seven fragments in every species, indicating that all the shigella species contained seven sets of ribosome rna operons. to determine ... | 2000 | 10612738 |
| production of ifn-gamma and il-10 to shigella invasins by mononuclear cells from volunteers orally inoculated with a shiga toxin-deleted shigella dysenteriae type 1 strain. | volunteers were orally administered invasive, non-shiga toxin-producing shigella dysenteriae 1 to establish a challenge model to assess vaccine efficacy. in stepwise fashion, four separate groups were given 3 x 10(2), 7 x 10(3), 5 x 10(4), or 7 x 10(5) cfu. using pbmc, proliferative responses and cytokine production were measured to s. dysenteriae whole-cell preparations and to purified recombinant invasion plasmid ags (ipa) c and ipad. anti-lps and anti-ipa abs and ab-secreting cells were also ... | 2000 | 10657678 |
| effects of caffeic acid, chlorogenic acid and ferulic acid on growth and arylamine n-acetyltransferase activity in shigella sonnei (group d). | arylamine n-acetyltransferase (nat) activities with 2-aminofluorene (2-af) as substrates were determined in shigella sonnei (group d) collected from patients with diarrhoeal disease. the nat activity was determined using an acetyl coa recycling assay and high pressure liquid chromatography. inhibition of growth studies from s. sonnei (group d) demonstrated that caffeic acid (ca), chlorogenic acid (cga) and ferulic acid (fa) elicited a dose-dependent bactericidal effect in s. sonnei (group d) cul ... | 2000 | 10677842 |
| evaluation of antibacterial activity of asparagus racemosus willd. root. | different concentrations (50, 100, 150 microg/ml) of the methanol extract of the roots of asparagus racemosus willd. showed considerable in vitro antibacterial efficacy against escherichia coli, shigella dysenteriae, shigella sonnei, shigella flexneri, vibrio cholerae, salmonella typhi, salmonella typhimurium, pseudomonas putida, bacillus subtilis and staphylococcus aureus. the effects produced by the methanol extract were compared with chloramphenicol. | 2000 | 10685109 |

| a new biological agent for treatment of shiga toxigenic escherichia coli infections and dysentery in humans. | gastrointestinal disease caused by shiga toxin-producing bacteria (such as escherichia coli o157:h7 and shigella dysenteriae) is often complicated by life-threatening toxin-induced systemic sequelae, including hemolytic-uremic syndrome. such infections can now be diagnosed very early in the course of the disease, but at present no effective therapeutic intervention is possible. here, we constructed a recombinant bacterium that displayed a shiga toxin receptor mimic on its surface, and it adsorbe ... | 2000 | 10700227 |
| nmr spectroscopy, molecular dynamics, and conformation of a synthetic octasaccharide fragment of the o-specific polysaccharide of shigella dysenteriae type 1. | a synthetic octasaccharide fragment (2) of the o-specific polysaccharide (1) of shigella dysenteriae type 1 has been studied as its methyl glycoside by one- and two-dimensional homo- and heteronuclear nmr spectroscopy. complete 1h and 13c nmr assignments have been generated, and the 13c spin-lattice relaxation times have been measured for the octasaccharide 2. a congener (6) of this octasaccharide containing one d-galactose residue with a specific 13c label at c-1 has been synthesized and used t ... | 2000 | 10723612 |
| antimicrobial resistance trends in shigella serogroups isolated in israel, 1990-1995. | from a total of 31319 shigella strains isolated in israel between 1990 and 1996, 17574 were sent to the national shigella reference center for typing. of these, 15287 were identified as shigella sonnei, 1833 as shigella flexneri, 327 as shigella boydii and 127 as shigella dysenteriae. in all, 4395 strains were tested for sensitivity to ampicillin, trimethoprim-sulfamethoxazole, tetracycline, chloramphenicol, nalidixic acid and ofloxacin. all strains tested were sensitive to ofloxacin, and only t ... | 2000 | 10746496 |
| structural analysis of phage-borne stx genes and their flanking sequences in shiga toxin-producing escherichia coli and shigella dysenteriae type 1 strains. | the stx-flanking regions of 49 shiga toxin-producing escherichia coli strains and nine shigella dysenteriae serotype 1 strains containing either stx, stx(1), stx(2), or stx(2) variant genes, were examined. we analyzed these regions by pcr using a set of primers with one primer specific for the respective stx gene and a second primer complementary to sequences of stx phages h-19b and 933w. we further characterized the amplification products by restriction endonuclease digestion and nucleotide seq ... | 2000 | 10948097 |
| [acute encephalopathy in children: a serious illness after an inauspicious beginning]. | three young children, 2 girls of 6 and 3.5 years and 1 boy aged 3.5 years, had complaints like vomiting and fever of what initially was thought to be a minor infection. however, their condition deteriorated within two days to such an extent that they died while being treated on the intensive care department. the rapid drop in consciousness, sometimes accompanied by convulsions, is an expression of increased intracranial pressure resulting from diffuse brain oedema, which itself is probably cause ... | 2000 | 10965363 |
| escherichia coli shiga toxin. | the stx family contains two types called stx1 (verotoxin 1: vt1 or shiga-like toxin: slt1) and stx2 (vt2, slt2); both toxins are encoded by bacteriophages. stx1 is identical to shiga toxin produced by shigella dysenteriae type i. stx2 is heterogeneous and immunologically different from stx1. although many variations are found in stx family, all stx has an a-b structure: the a subunit has n-glycosidase activity and the b subunit binds to a membrane glycolipid, globotriaosylceramide (gb3). the a s ... | 2000 | 10994531 |
| characterization and expression of hmur, a tonb-dependent hemoglobin receptor of porphyromonas gingivalis. | the gram-negative pathogen porphyromonas gingivalis requires hemin for growth. hemoglobin bound to haptoglobin and hemin complexed to hemopexin can be used as heme sources, indicating that p. gingivalis must have a means to remove the hemin from these host iron-binding proteins. however, the specific mechanisms utilized by p. gingivalis for the extraction of heme from heme-binding proteins and for iron transport are poorly understood. in this study we have determined that a newly identified tonb ... | 2000 | 11004172 |
| role of porin of shigella dysenteriae type 1 in modulation of lipopolysaccharide mediated nitric oxide and interleukin-1 release by murine peritoneal macrophages. | the ability of shigella dysenteriae type 1 porin to induce the release of nitric oxide (no) and interleukin-1 (il-1) from peritoneal macrophages of mouse and to regulate lipopolysaccharide (lps) and gamma interferon (ifn-gamma) mediated release of the two proinflammatory mediators was investigated. porin released nitrite when added to macrophage cultures. a maximum of 3.2-fold nitrite release by macrophages was observed with 100 ng ml(-1) of porin. the nitrite release of lps was enhanced signifi ... | 2000 | 11024352 |
| tonb is required for intracellular growth and virulence of shigella dysenteriae. | to assess the importance of tonb-dependent iron transport systems to growth of shigella in vivo, a tonb mutant of shigella dysenteriae was isolated and tested in cultured cells. the tonb mutant invaded epithelial cells, but did not form plaques in confluent monolayers of henle cells, indicating an inability of this mutant to spread from cell to cell. the rate of intracellular multiplication of the tonb mutant was reduced significantly compared to that of the wild type. the loss of virulence in t ... | 2000 | 11035742 |
| a novel is-like element frequently inserted in a putative virulence regulator in bovine mastitis isolates of streptococcus dysgalactiae. | streptococcus dysgalactiae, a lancefield group c streptococcus, is commonly isolated from bovine mastitis. we recently identified a putative regulon in two s. dysgalactiae strains, 8215 and epi9, consisting of two consecutive genes, dmg and dem, coding for a possible regulatory protein and an m-like protein with fibrinogen- and igg-binding-properties, respectively. during these studies a short sequence homologous to an is element was found to be inserted in the dmg gene of strain 8215. the prese ... | 2000 | 11078648 |
| induction of mrna for tumor necrosis factor-alpha and interleukin-1 beta in mice brain, spleen and liver in an animal model of shigella-related seizures. | the pathogenesis of neurological symptoms, the most common extraintestinal complication of childhood shigellosis, is unclear. to elucidate the mechanisms involved, we developed an animal model and demonstrated that tnf alpha and il-1 beta play a role. | 2000 | 10804924 |
| synthesis of the tetrasaccharide related to the repeating unit of the antigen from shigella dysenteriae type 5. | starting from l-rhamnose, d-mannose and 2-amino-2-deoxy-d-glucose hydrochloride, two disaccharide blocks, namely, ethyl 2,4-di-o-benzyl-3-o-[(r)-1-(methoxycarbonyl)ethyl]-alpha-l-rhamnopyranos yl-(1-->3)-2-o-acetyl-4,6-di-o-benzyl-1-thio-alpha-d-mannopyranoside and 2-(trimethylsilyl)ethyl 2-o-acetyl-3,6-di-o-benzyl-alpha-d-mannopyranosyl-(1-->3)-4,6-di-o-benzy l-2-deoxy-2-phthalimido-beta-d-glucopyranoside, were synthesised and then allowed to react in the presence of n-iodosuccinimide and trifl ... | 2000 | 10839118 |
| disease-dependent changes in t-cell populations in patients with shigellosis. | in shigellosis, bacterial infection is associated with an extensive inflammation of the rectal mucosa, resulting in bloody dysentery. the role of t-cell-mediated pro-inflammatory mechanisms has been implicated in this process, but the specific role of t-cell subsets is still not well understood. in this study we attempted to identify the changes in t-cell populations in patients with shigellosis during the disease course. the t-cell subset distribution was analyzed by immunohistochemistry in the ... | 2000 | 10843411 |
