bovine milk antibodies for health.the immunoglobulins of bovine colostrum provide the major antimicrobial protection against microbial infections and confer a passive immunity to the newborn calf until its own immune system matures. the concentration in colostrum of specific antibodies against pathogens can be raised by immunising cows with these pathogens or their antigens. immune milk products are preparations made of such hyperimmune colostrum or antibodies enriched from it. these preparations can be used to give effective sp ...200011242458
[value of antibiotype and bacteriocinotype for differentiating shigella strains isolated in argentina].the aim of the present work was to analyse the phenotypical characteristics of shigella strains in order to evaluate their possible utilisation as epidemiological markers. for one year, we studied 95 strains of shigella obtained from stool specimens of patients with dysentery. bacteria came from various health care centres in the states of chaco and corrientes (argentina). bacteria were identified by using classical biochemical methods. all strains were serotyped and susceptibility patterns were ...200011775312
src tyrosine kinase activity down-regulates rho-dependent responses during shigella entry into epithelial cells and stress fibre formation.invasion of epithelial cells by shigella, the causative agent of bacillary dysentery, is dependent upon the formation of characteristic membrane ruffles that engulf the bacteria in a macropinocytic-like process. we show here that cdc42 and rac gtpases, but not rho;, are critical for actin polymerisation, whereas rho; is necessary for the recruitment of ezrin and src at the site of entry. remarkably, cells expressing constitutively active src did not show ezrin recruitment at shigella entry foci. ...200010591626
interaction of enteropathogenic or enterohemorrhagic escherichia coli with hela cells results in translocation of cortactin to the bacterial adherence site.infection of cultured hela epithelial cells with enteropathogenic escherichia coli (epec) or enterohemorrhagic e. coli (ehec) o157:h7 results in accumulation of cortactin under the adherent bacteria. tyrosine phosphorylation of cortactin is not induced following hela cell infection with ehec or epec, contrary to what has been reported to occur with shigella flexneri.200010603412
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 ...200010612738
serotype-converting bacteriophages and o-antigen modification in shigella flexneri.o-antigen modification (serotype conversion) in shigella flexneri, which is an important virulence determinant, is conferred by temperate bacteriophages. several serotype-converting phages have been isolated and preliminary characterization has identified the genes involved in o-antigen modification, and has also provided insight into the molecular biology of these phages.200010637639
effect of erythromycin on shigella infection of caco-2 cells.erythromycin (em), one of the macrolides, shows a dose-dependent effect on shigella flexneri invasion of caco-2 cells even at concentrations less than the minimum inhibitory concentration (submic). ls13, a strain of s. flexneri 1b, invaded caco-2 cells in vitro. when the strain was treated with submic of em, the invasion efficiency decreased. the carrier rate of the invasion plasmid containing virulence genes was reduced by em treatment, as determined by the colony pigmentation test on congo red ...200010640609
identification of a novel genetic locus that is required for in vitro adhesion of a clinical isolate of enterohaemorrhagic escherichia coli to epithelial cells.enterohaemorrhagic escherichia coli (ehec) are food-borne intestinal pathogens with a low infectious dose. adhesion of some ehec strains to epithelial cells is attributed, in part, to intimin, but other factors may be required for the intestinal colonizing ability of these bacteria. in order to identify additional adherence factors of ehec, we generated transposon mutants of a clinical ehec isolate of serotype o111:h-, which displayed high levels of adherence to cultured chinese hamster ovary (c ...200010652089
e. coli hemolysin e (hlye, clya, shea): x-ray crystal structure of the toxin and observation of membrane pores by electron microscopy.hemolysin e (hlye) is a novel pore-forming toxin of escherichia coli, salmonella typhi, and shigella flexneri. here we report the x-ray crystal structure of the water-soluble form of e. coli hlye at 2.0 a resolution and the visualization of the lipid-associated form of the toxin in projection at low resolution by electron microscopy. the crystal structure reveals hlye to be the first member of a new family of toxin structures, consisting of an elaborated helical bundle some 100 a long. the elect ...200010660049
shigella flexneri 2a strain cvd 1207, with specific deletions in virg, sen, set, and guaba, is highly attenuated in humans.a phase 1 clinical trial was conducted among 35 healthy adult volunteers to evaluate the safety, immunogenicity, and shedding of different doses of cvd 1207, a live attenuated shigella flexneri 2a vaccine candidate with specific deletion mutations in virg, sen, set, and guaba. cvd 1207 retains the ability to invade epithelial cells but cannot effectively spread intercellularly after invasion (deltavirg), does not produce enterotoxin (deltasen and deltaset), and has limited proliferation in vivo ...200010678904
induction of necrosis in human neutrophils by shigella flexneri requires type iii secretion, ipab and ipac invasins, and actin polymerization.infection by shigella flexneri is characterized by infiltration of neutrophils in the intestinal mucosa and by a strong inflammatory reaction. although neutrophils are constitutively programmed to die by apoptosis, we show that isolated human neutrophils undergo necrosis 2 h after infection with virulent s. flexneri strain m90t but not with the virulence plasmid-cured strain bs176. this was demonstrated by the release of azurophil granule proteins concomitant with the release of lactate dehydrog ...200010678940
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.200010685109
transfer rna modification, temperature and dna superhelicity have a common target in the regulatory network of the virulence of shigella flexneri: the expression of the virf gene.full expression of the virulence genes of shigella flexneri requires the presence of two modified nucleosides in the trna [queuosine, q34, present in the wobble position (position 34) and 2-methylthio-n6-isopentenyladenosine (ms2i6a37, adjacent to and 3' of the anticodon)]. the synthesis of these two nucleosides depends on the products of the tgt and miaa genes respectively. we have shown that the intracellular concentration of the virulence-related transcriptional regulator virf is reduced in t ...200010692168
construction of an efficient expression system for agrobacterium tumefaciens based on the coliphage t5 promoter.a versatile expression vector utilizing a promoter of coliphage t5, p(n25) (gentz and bujard, 1985. j. bacteriol. 164, 70-77) and a derivative of the incw broad-host-range plasmid pjb20 (beaupré et al., 1997. j. bacteriol. 179, 78-89) has been developed. this vector successfully expresses virulence proteins of agrobacterium tumefaciens encoded by virg and a mutant allele of vira, vira (delta1-284, g665d) in escherichia coli as well as in a. tumefaciens. the signal transduction proteins vira (del ...200010721702
emergence of antimicrobial-resistant shigellosis in oregon.ampicillin and trimethoprim-sulfamethoxazole (tmp-smz) are currently considered acceptable empirical therapy for shigellosis in developed countries. however, there are few recently reported studies on antimicrobial resistance among shigellae isolated in the united states. we examined the epidemiology of shigellosis and the antimicrobial susceptibility of shigella species isolated in oregon from july 1995 through june 1998. of 430 isolates, 410 were identified to the species level: shigella sonne ...200010722437
clostridium difficile recombinant toxin a repeating units as a carrier protein for conjugate vaccines: studies of pneumococcal type 14, escherichia coli k1, and shigella flexneri type 2a polysaccharides in mice.unlike the native protein, a nontoxic peptide (repeating unit of the native toxin designated raru) from clostridium difficile toxin a (cdta) afforded an antigen that could be bound covalently to the surface polysaccharides of pneumococcus type 14, shigella flexneri type 2a, and escherichia coli k1. the yields of these polysaccharide-protein conjugates were significantly increased by prior treatment of raru with succinic anhydride. conjugates, prepared with raru or succinylated (rarusucc), were a ...200010722615
shigella actin-based motility in the presence of truncated vinculin.mounting evidence supports the role of truncated vinculin in the intracellular actin-based motility of shigella flexneri. vinculin's role was recently questioned by goldberg [1997: cell motil cytoskeleton 37:44-53] who observed shigella motility in mouse embryonal carcinoma 5.51 cells, a genetically modified cell line that reputedly lacked vinculin. that challenge implicitly relied on the assumption that 5.51 cells had no detectable vinculin polypeptide and lacked full-length vinculin mrna. desp ...200010744860
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 ...200010746496
antagonistic effect of lactobacillus acidophilus, saccharomyces boulardii and escherichia coli combinations against experimental infections with shigella flexneri and salmonella enteritidis subsp. typhimurium in gnotobiotic mice.lactobacillus acidophilus, saccharomyces boulardii and escherichia coli are probiotic strains used individually to protect against enteropathogenic agents. in order to determine if a synergistic effect of the individual protective mechanisms ordinarily attributed to each of these biotherapeutic agents is possible, we orally administered lact. acidophilus h2b20, s. boulardii and e. coli emo (lse) to germfree mice. ten days after colonization of the digestive tract, groups of animals associated (e ...200010747216
[antimicrobial resistance of shigella spp. in córdoba, argentina, during the period 1990-1997].this study analyzed the evolution of antimicrobial resistance in 771 isolates of shigella spp. obtained from a total of 9,195 feces cultures done between 1990 and 1997 in a children's hospital in córdoba, argentina. s. flexneri, which was responsible for 73% of the shigella infections, was the species with the greatest resistance. the frequency of s. flexneri resistance to the three antibiotics most used (ampicillin, trimethoprim-sulfamethoxazole, and chloramphenicol) increased from 10% in 1990 ...200010748662

the stability region of the large virulence plasmid of shigella flexneri encodes an efficient postsegregational killing system.the large virulence plasmid pmysh6000 of shigella flexneri contains a determinant that is highly effective in stabilizing otherwise unstable plasmids in escherichia coli. expression of two small contiguous genes, mvpa and mvpt (formerly termed stborf1 and stborf2), was shown to be sufficient for stability. mutations in mvpt abolished plasmid stability, and plasmids expressing only mvpt killed the cells unless mvpa was supplied from a separate plasmid or from the host chromosome. when replication ...200010762240
complete nucleotide sequence of tn10.the complete nucleotide sequence of tn10 has been determined. the dinucleotide signature and percent g+c of the sequence had no discontinuities, indicating that tn10 constitutes a homogeneous unit. the new sequence contained three new open reading frames corresponding to a glutamate permease, repressors of heavy metal resistance operons, and a hypothetical protein in bacillus subtilis. the glutamate permease was fully functional when expressed, but tn10 did not protect escherichia coli from the ...200010781570
detection of pcr products of the ipah gene from shigella and enteroinvasive escherichia coli by enzyme linked immunosorbent assay.pcr techniques applied to diarrheal stools reliably diagnose shigella and enteroinvasive escherichia coli (eiec) infections. identification of pcr products using agarose gel electrophoresis (age) and hybridization with dna probes has several shortcomings. automated methods of identifying pcr products that process larger numbers of specimens can facilitate epidemiologic studies and standardize results. in this study, we used elisa following pcr to detect ipah gene sequences of shigella and eiec f ...200010794934
a high incidence of shigella-induced arthritis in a primate species: major histocompatibility complex class i molecules associated with resistance and susceptibility, and their relationship to hla-b27.the human major histocompatibility complex (mhc) class i gene, hla-b27, is a strong risk factor for susceptibility to a group of disorders termed spondyloarthropathies. rodents that express hla-b27 develop spondyloarthropathies, implicating hla-b27 in the etiology of these disorders. to determine whether an hla-b27-like molecule was associated with spondyloarthropathies in nonhuman primates, we analyzed the mhc class i cdnas expressed in a cohort of rhesus macaques that developed reactive arthri ...200010803844
shigella flexneri ipah(7.8) facilitates escape of virulent bacteria from the endocytic vacuoles of mouse and human macrophages.the behavior of shigella flexneri ipah mutants was studied in human monocyte-derived macrophages (hmdm), in 1-day-old human monocytes, and in j774 mouse macrophage cell line. in hmdm, strain pwr700, an ipah(7.8) deletion mutant of s. flexneri 2a strain 2457t, behaved like the wild-type strain 2457t. this strain caused rapid host cell death by oncosis, and few bacterial cfu were recovered after incubation in the presence of gentamicin as previously described for 2457t-infected hmdm. however, anal ...200010816519
interaction of shigella flexneri ipac with model membranes correlates with effects on cultured cells.invasion of enterocytes by shigella flexneri requires the properly timed release of ipab and ipac at the host-pathogen interface; however, only ipac has been found to possess quantifiable activities in vitro. we demonstrate here that when added to cultured cells, purified ipac elicits cytoskeletal changes similar to those that occur during shigella invasion. this ipac effect may correlate with its ability to interact with model membranes at physiological ph and to promote entry by an ipac mutant ...200010816532
curli loci of shigella spp.an unstable chromosomal element encoding multiple antibiotic resistance in shigella flexneri serotype 2a was found to include sequences homologous to the csg genes encoding curli in escherichia coli and salmonella enterica serovar typhimurium. as curli have been implicated in the virulence of serovar typhimurium, we investigated the csg loci in all four species of shigella. dna sequencing and pcr analysis showed that the csg loci of a wide range of shigella strains, of diverse serotypes and diff ...200010816548
matrix-assisted laser desorption/ionization time-of-flight mass spectrometric detection of bacterial biomarker proteins isolated from contaminated water, lettuce and cotton cloth.matrix-assisted laser desorption/ionization time-of-flight (maldi-tof) mass spectra of bacterial proteins were obtained from water, lettuce and cloth samples contaminated with shigella flexneri, escherichia coli, and aeromonas hydrophila. spectra were obtained using proteins directly isolated from water (or water used for rinsing samples) without culturing the bacteria. for s. flexneri and e. coli, two marker ions for specific proteins associated with a virulence-related property (acid resistanc ...200010825256
rho family gtpase cdc42 is essential for the actin-based motility of shigella in mammalian cells.shigella, the causative agent of bacillary dysentery, is capable of directing its movement within host cells by exploiting actin dynamics. the virg protein expressed at one pole of the bacterium can recruit neural wiskott-aldrich syndrome protein (n-wasp), a downstream effector of cdc42. here, we show that cdc42 is required for the actin-based motility of shigella. microinjection of a dominant active mutant cdc42, but not rac1 or rhoa, into swiss 3t3 cells accelerated shigella motility. in add-b ...200010839806
caspase-1 activation of il-1beta and il-18 are essential for shigella flexneri-induced inflammation.caspases are intracellular proteases that mediate mammalian cell apoptosis. caspase-1 (casp-1) is a unique caspase because it activates the proinflammatory cytokines interleukin (il)-1beta and il-18. shigella flexneri, the etiological agent of bacillary dysentery, induces macrophage apoptosis, which requires casp-1 and results in the release of mature il-1beta and il-18. here we show that casp-1(-/-) mice infected with s. flexneri do not develop the acute inflammation characteristic of shigellos ...200010843390
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 ...200010843411
