brucella evades macrophage killing via virb-dependent sustained interactions with the endoplasmic reticulum.the intracellular pathogen brucella is the causative agent of brucellosis, a worldwide zoonosis that affects mammals, including humans. essential to brucella virulence is its ability to survive and replicate inside host macrophages, yet the underlying mechanisms and the nature of the replicative compartment remain unclear. here we show in a model of brucella abortus infection of murine bone marrow-derived macrophages that a fraction of the bacteria that survive an initial macrophage killing proc ...200312925673
[genetic variability of bordetella pertussis strains. part i. current knowledge].variability of b. pertussis genome concerning s1 subunit of pertussis toxin (ptxs1) and pertactin (prn) genes has recently been recognised. studies clearly showed differences in the dna patterns and ptxs1 and prn alleles present in b. pertussis strains used for production of pertussis component in the dtp vaccine, in comparison to strains presently isolated from clinical materials. this trend has been observed in highly immunized populations with a long history of pertussis vaccination (the neth ...200312926327
[genetic variability of bordetella pertussis strains. part ii. perspectives].in some highly immunized countries with long history of pertussis vaccination (the netherlands, finland, poland, usa, france, great britain) differences in the dna patterns and ptxs1 and prn alleles present in b. pertussis strains used for production of pertussis component in the dtp vaccine, in comparison to strains presently isolated from clinical materials have been found. studies on efficacy of whole-cell and acellular pertussis vaccines in elimination of b. pertussis strains harbouring diff ...200312926328
bordetella pertussis acquires resistance to complement-mediated killing in vivo.in order to initially colonize a host, bacteria must avoid various components of the innate immune system, one of which is complement. the genus bordetella includes three closely related species that differ in their ability to resist complement-mediated killing. bordetella parapertussis and bordetella bronchiseptica resist killing in naïve serum, a characteristic that may aid in efficient respiratory tract colonization and has been attributed to expression of o antigen. bordetella pertussis lack ...200312933835
crucial role of antibodies to pertactin in bordetella pertussis immunity.pertussis, a serious infectious disease of the respiratory tract caused by bordetella pertussis, is reemerging in vaccinated populations. efforts to curtail this disease are hampered by limited insight into the basis of protective immunity. opsonophagocytosis was recently found to play a central role in cellular bactericidal activity against b. pertussis. in the present study, we studied the specificity of opsonic antibodies. anti-pertactin antibodies, but not anti-pertussis toxin, anti-fimbriae ...200312934190
role of nuclear factor-kappa b in the regulation of intercellular adhesion molecule 1 after infection of human bronchial epithelial cells by bordetella pertussis.previous work has demonstrated that infection of human bronchial epithelial cells by bordetella pertussis up-regulates intercellular adhesion molecule-1 (icam-1) gene and protein expression. it has also been shown that interaction of the arg-gly-asp (rgd) site of filamentous hemagglutinin (fha) with host cell very late antigen (vla)-5 (alpha 5 beta 1 integrin) is required for the up-regulation of epithelial icam-1 expression, and that pertussis toxin (pt) impairs this response. we therefore exam ...200312946329
in vitro selection for enzymatic activity: a model study using adenylate cyclase.an in vitro enzyme selection that can, in principle, be generalised to most chemical reactions, is described. it makes use of filamentous phage display and of a tailor-made antibody fragment directed against the reaction product. the conversion of atp into 3',5'-cyclic amp catalysed by bordetella pertussis adenylate cyclase is taken as an example.200312946341
identification and characterization of the last two unknown genes, dapc and dapf, in the succinylase branch of the l-lysine biosynthesis of corynebacterium glutamicum.the inspection of the complete genome sequence of corynebacterium glutamicum atcc 13032 led to the identification of dapc and dapf, the last two unknown genes of the succinylase branch of the l-lysine biosynthesis. the deduced dapf protein of c. glutamicum is characterized by a two-domain structure and a conserved diaminopimelate (dap) epimerase signature. overexpression of dapf resulted in an 8-fold increase of the specific epimerase activity. a defined deletion in the dapf gene led to a reduce ...200312948639
the host response to anthrax lethal toxin: unexpected observations.bacillus anthracis, the causative agent of anthrax, is believed to induce disease and death in humans in an endotoxic shock-like manner. a comprehensive study of the effects of anthrax toxin in mice demonstrates that toxin-induced death is mediated not by cytokine release, as previously thought, but by hypoxia-induced liver failure. the study strongly suggests that the therapies developed for treatment of cytokine-mediated septic shock will not be appropriate for the treatment of anthrax.200312952914
development and clinical evaluation of an internally controlled, single-tube multiplex real-time pcr assay for detection of legionella pneumophila and other legionella species.a multiplex real-time pcr assay for detection of legionella pneumophila and legionella spp. and including an internal control was designed. legionella species, l. pneumophila, and the internal control were detected simultaneously by probes labeled with 6-carboxy-fluorescein, hexachlorofluorescein, and indodicarbocyanine, respectively. therefore, no postamplification analysis was required in order to distinguish the targets. the sensitivity of both assays was 2.5 cfu/ml, and from analysis of 10 c ...200312958219
evaluation of real-time pcr for detection of and discrimination between bordetella pertussis, bordetella parapertussis, and bordetella holmesii for clinical diagnosis.pcr is increasingly being used as a diagnostic test for the detection of bordetella pertussis and bordetella parapertussis dna, as it has improved sensitivity and specificity in comparison to conventional techniques. the assay described here uses the two insertion sequences is481 and is1001 for b. pertussis and b. parapertussis, respectively, with detection by molecular beacons. the real-time pcr for is481 detects both b. pertussis and bordetella holmesii, and the real-time pcr for is1001 detect ...200312958235
toll-like receptor 4-mediated innate il-10 activates antigen-specific regulatory t cells and confers resistance to bordetella pertussis by inhibiting inflammatory pathology.signaling through toll-like receptors (tlr) activates dendritic cell (dc) maturation and il-12 production, which directs the induction of th1 cells. we found that the production of il-10, in addition to inflammatory cytokines and chemokines, was significantly reduced in dcs from tlr4-defective c3h/hej mice in response to bordetella pertussis. tlr4 was also required for b. pertussis lps-induced maturation of dcs, but other b. pertussis components stimulated dc maturation independently of tlr4. th ...200312960338
preventing infectious diseases during and after international adoption.families of internationally adopted children face risks associated with travel if they pick up their children overseas. unlike other travelers, they also face risks because of close contact with a child with uncertain infection and vaccination status. tuberculosis organisms, hepatitis a virus, hepatitis b virus, and measles virus have been transmitted from adopted children to family and community members. intestinal parasites, bordetella pertussis, and other infectious disease agents can also be ...200312965946
ancient origin of the tryptophan operon and the dynamics of evolutionary change.the seven conserved enzymatic domains required for tryptophan (trp) biosynthesis are encoded in seven genetic regions that are organized differently (whole-pathway operons, multiple partial-pathway operons, and dispersed genes) in prokaryotes. a comparative bioinformatics evaluation of the conservation and organization of the genes of trp biosynthesis in prokaryotic operons should serve as an excellent model for assessing the feasibility of predicting the evolutionary histories of genes and oper ...200312966138
diagnosis and treatment of multiple sclerosis and amyotrophic lateral sclerosis: neuropathies from bordetella pertussis.having found positive the research for anti-bordetella antibodies in the 95.47% of 92 patients affected by defined multiple sclerosis and in the 100% of 55 patients affected by non-patched neuropathies (amyotrophic lateral sclerosis and correlated neuropathies), i reassessed the pathogenesis of the neuropathies from bordetella pertussis. in the two categories of neuropathies (with and without patches), the beginning pathogenetic mechanisms are the same: 1) pertussis re-infection in patients with ...200312975723
