the alveolar macrophage: the trojan horse of bacillus anthracis.bacillus anthracis, the causative agent of anthrax, has a particular strategy for invading the host and crossing the alveolar barrier. b. anthracis survives within alveolar macrophages, after germination within the phagolysosome, then enters the external medium where it proliferates. recent data have shown that edema toxin and lethal toxin are the major genetic determinants mediating the survival of germinated spores within macrophages. here, recent advances in the analysis of b. anthracis patho ...200212217505
gi anthrax: report of one case confirmed with autopsy.bacillus anthraces is a non-motile, rod like, gram-positive and aerobic bacillus that produces central oval-shaped spores and characterized by rough, irregular and often comma-shaped colonies in blood agar. about 95% of human anthrax is cutaneous and 5% respiratory. gi anthrax, a very rare type, has been reported in less than 1% of all cases. we thus report a case of gi anthrax with autopsy findings.200212218950

effect of bacillus anthracis lethal toxin on human peripheral blood mononuclear cells.lethal toxin (letx) plays a central role in anthrax pathogenesis, however a cytotoxicity of letx has been difficult to demonstrate in vitro. no cytolytic effect has been reported for human cells, in contrast to murine cell lines, indicating that cell lysis can not be considered as a marker of letx activity. we have recently shown that murine macrophage-like raw 264.7 cells treated with letx or infected with anthrax spores underwent changes typical of apoptotic death. here we demonstrate that cel ...200212220662
introduction: anthrax history, disease and ecology.the familiarity with the ancient disease anthrax from the second millennium b.c. through the second millennium a.d. is reviewed, providing the backdrop to the modern understanding of this disease as covered in the remainder of the volume. by means of an overview of the aetiology, ecology, epidemiology, clinical manifestations, pathology and bacteriology of the naturally acquired disease, this opening chapter also lays down the groundwork for the subsequent state-of-the-art chapters.200212224519
macrophage interactions.b. anthracis virulence is the sum of the contributions of factors involved in toxicity, growth and persistence in the host. recent data has revealed that the interactions between b. anthracis and macrophage is central to the b. anthracis pathogenesis. this review presents and describes tactics by which b. anthracis not only overcomes and avoids macrophages but also perverts the host defense immune system and defense-related products to its advantage. the understanding of the complex network of s ...200212224520
bacillus anthracis genetics and virulence gene regulation.the bacillus anthracis genome consists of an approximately 5.3-mb chromosome and two plasmids, pxo1 (182 kb) and pxo2 (96 kb). genetic analysis has focused primarily on the structural genes for the anthrax toxin proteins, paga, lef, and cya, the biosynthetic genes for capsule synthesis, capb, capc, and capa, and a gene associated with depolymerization of capsule, dep. the three toxin genes are located at distinct loci on pxo1, while the cap and dep genes are arranged in an apparent operon on pxo ...200212224521
bacillus anthracis evolution and epidemiology.bacillus anthracis is a pathogen that is widely distributed around the globe. however, this great distribution is not accompanied by great genetic diversity. although subtle morphological and biochemical differences exist, the underlying genetic basis for this plasticity is not known. indeed, very few single nucleotide differences have been detected among isolates and the only documented high variable sequences are associated with variable number tandem repeated (vntr) sequences. the differences ...200212224522
anthrax vaccines.the only impetus for the development of new anthrax vaccines is to protect humans against the intentional use of bacillus anthracis as a bioterrorist or warfare agent. live attenuated vaccines against anthrax in domesticated animals were among the very first vaccines developed. this was followed by the development of nonliving component vaccines leading to the eventual licensure of protein-based vaccines for human use in the 1970s. this chapter will review the recent advances in developing prote ...200212224523
structure and function of anthrax toxin.anthrax toxin is a binary a-b toxin comprised of protective antigen (pa) and two enzymatic moieties, edema factor (ef) and lethal factor (lf). in the presence of a host cell-surface receptor, pa can mediate the delivery of ef and lf from the extracellular milieu into the host cell cytosol to effect toxicity. in this delivery, pa undergoes multiple structural changes--from a monomer to a heptameric prepore to a membrane-spanning heptameric pore. the catalytic factors also undergo dramatic structu ...200212224524
bacillus anthracis cell envelope components.bacillus anthracis is a gram-positive bacterium harboring a complex parietal architecture. the cytoplasmic membrane is surrounded by a thick peptidoglycan of the a1 gamma type. only one associated polymer, a polysaccharide composed of galactose, n-acetylglucosamine, and n-acetylmannosamine, is covalently linked to the peptidoglycan. outside the cell wall is an s-layer. two proteins can each compose the s-layer. they are noncovalently anchored to the cell wall polysaccharide by their slh n-termin ...200212224525
risk analysis and risk management in an uncertain world.the tragic attacks of september 11 and the bioterrorist threats with respect to anthrax that followed have raised a set of issues regarding how we deal with events where there is considerable ambiguity and uncertainty about the likelihood of their occurrence and their potential consequences. this paper discusses how one can link the tools of risk assessment and our knowledge of risk perception to develop risk management options for dealing with extreme events. in particular, it suggests ways tha ...200212224739
the role of risk analysis in understanding bioterrorism.recent events have made the domestic risk from bioterrorism more tangible. the risk management process so far, however, has not benefited from many of the contributions that analysts, communicators, and managers can make to the public discourse. risk professionals can contribute much to the understanding of and solutions to bioterrorist events and threats. this article will provide an overview of the bioterrorism problem and outline a number of areas to which members of the society for risk anal ...200212224741

bioterrorism--are you ready for the silent killer?current biological threats to the united states have generated fear and panic among many, but nursing professionals who are educated about bioterrorism and its effects can answer questions confidently and calm fears when peers, family members, and friends ask about this issue. perioperative nurses can become ambassadors of confidence via their ability to project calm and thus stem the tide of panic and fear. this article explains the definition of bioterrorism, its history, biological agents and ...200212227287
occupational health guidelines for remediation workers at bacillus anthracis-contaminated sites--united states, 2001-2002.despite the apparently low disease rate from exposure, protection for remediation workers at b. anthracis-contaminated sites is warranted because inhalational anthrax is rapidly progressive and highly fatal, ppe does not guarantee 100% protection, and the risk for developing disease cannot be characterized adequately. the guidelines described here go beyond hazwoper requirements and include recommendations for treating inhalation exposure to b. anthracis spores as a medical emergency, medical fo ...200212227440
protecting building environments from airborne chemical, biologic, or radiologic attacks.in november 2001, following the discovery that letters containing bacillus anthracis had been mailed to targeted locations in the united states, the secretary of the u.s. department of health and human services requested site assessments of an array of public- and private-sector buildings by a team of engineers and scientists from cdc's national institute for occupational safety and health (niosh). in november 2001, this team assessed six buildings, including a large hospital and medical researc ...200212227441
macrophage-enhanced germination of bacillus anthracis endospores requires gers.germination of bacillus anthracis sterne and plasmidless delta-sterne endospores was dramatically enhanced in raw264.7 macrophage-like cells, while germination of nonpathogenic bacillus endospores was not. elimination of gers, a germinant receptor locus, caused a complete loss of cell-enhanced germination, implicating gers in the breaking of endospore dormancy in vivo.200212228320
management of anthrax.from 3 october 2001 through 16 november 2001, in the united states, there were 18 confirmed cases of inhalational and cutaneous anthrax, an additional 4 suspected cases of cutaneous anthrax, and 5 deaths due to inhalational anthrax. although the number of cases was relatively small, this experience brought bioterrorism and its potential to sharp focus as thousands of people began receiving prophylactic antibiotics after possible exposure to anthrax spores. these events have resulted in a substan ...200212228822

antimicrobial susceptibility of bacillus anthracis in an endemic area.we aimed to test the antimicrobial susceptibility of 28 bacillus anthracis strains isolated from cutaneous anthrax cases to various antimicrobial agents using the sceptor automatic system in an anthrax endemic area. all strains tested were susceptible to penicillin (mic < or = 0.03 microg/ml). piperacillin-tazobactam and carbapenems showed good activity towards all strains. trimethoprim-sulfamethoxazole and cefepime had no activity. strains were also tested with other antimicrobials.200212238569
a case of anthrax meningitis.meningeal anthrax is a very rare complication of the cutaneous, respiratory and gastrointestinal form of anthrax infection. anthrax bacilli, most commonly enter the body via the skin, and the organism then disseminates to the central nervous system via the hematogenous or lymphatic routes leading to fatal bacterial meningitis, even with intensive antibacterial therapy.200212238584
bioterrorism vs. health security--crafting a plan of preparedness.bioterrorism, once a subject of fantasy and speculation, has become all too real in a world turned upside down by the september 11, 2001. series of events. an essential, but as yet unanswered, question has become a crucial topic for discussion on the nightly news and in living rooms across the united states: how much of a terrorist threat do we face, and what must be done to control its potential for mass destruction? this article seeks to both answer this question and explore proper plans of pr ...200212243568

chemical and biological weapons. implications for anaesthesia and intensive care.in the wake of recent atrocities there has been renewed apprehension regarding the possibility of chemical and biological weapon (cbw) deployment by terrorists. despite various international agreements that proscribe their use, certain states continue to develop chemical and biological weapons of mass destruction. of greater concern, recent historical examples support the prospect that state-independent organizations have the capability to produce such weapons. indeed, the deliberate deployment ...200212378672
postexposure prophylaxis against anthrax: evaluation of various treatment regimens in intranasally infected guinea pigs.the efficiency of postexposure prophylaxis against bacillus anthracis infection was tested in guinea pigs infected intranasally with either vollum or strain atcc 6605 spores (75 times the 50% lethal dose [ld(50)] and 87 times ld(50,) respectively). starting 24 h postinfection, animals were treated three times per day for 14 days with ciprofloxacin, tetracycline, erythromycin, cefazolin, and trimethoprim-sulfamethoxazole (tmp-smx). administration of cefazolin and tmp-smx failed to protect the ani ...200212379702
rapid genotyping of bacillus anthracis strains by real-time polymerase chain reaction.rapid and accurate identification of bacillus anthracis is critical for patient care as well as outbreak control. we have developed 3 separate pcr based assays using fluorescence resonance energy transfer (fret) to detect the presence of pxo1, pxo2 plasmids and a chromosomal marker. a set of amplification primers and probes were used in each assay. the probes were ad jacently placed inside the primer sites and were 1-bp apart. the upstream probe was labeled with fluorescein at the 3' end, and th ...200212381573
basis for the extraordinary genetic stability of anthrax.over 500 isolates of anthrax bacillus from around the world represent one of the most genetically homogeneous microbes. there are three possibilities for this genetic stability: (1) anthrax has an extraordinarily high fidelity repair system, (2) genetic damage to anthrax is usually lethal, and/or (3) a highly demanding and selective process exists in its environment that is necessary for the completion of its life cycle. using probes made from genes selected by growth of an escherichia coli expr ...200212381574

molecular analysis of rifampin resistance in bacillus anthracis and bacillus cereus.rifampin-resistant mutants were selected from uv-light-treated bacillus cereus (20 mutants) and attenuated b. anthracis (23 mutants). in addition, spontaneous rifampin-resistant mutants were also isolated in attenuated b. anthracis (22 mutants). the rifampin resistance clusters of the rpob gene were sequenced for all 65 mutants. mutations associated with resistance were consistent with those from other bacteria, though two novel changes were observed. the spontaneous rate of resistance was estim ...200211796364
efficiency of protection of guinea pigs against infection with bacillus anthracis spores by passive immunization.the efficacy of passive immunization as a postexposure prophylactic measure for treatment of guinea pigs intranasally infected with bacillus anthracis spores was evaluated. antisera directed either against the lethal toxin components (pa or lf) or against a toxinogenic strain (sterne) were used for this evaluation. all antisera exhibited high enzyme-linked immunosorbent assay titers against the corresponding antigens, high titers of neutralization of cytotoxicity activity in an in vitro mouse ma ...200211796581
anthrax spores make an essential contribution to vaccine efficacy.anthrax is caused by bacillus anthracis, a gram-positive spore-forming bacterium. septicemia and toxemia rapidly lead to death in infected mammal hosts. currently used acellular vaccines against anthrax consist of protective antigen (pa), one of the anthrax toxin components. however, in experimental animals such vaccines are less protective than live attenuated strains. here we demonstrate that the addition of formaldehyde-inactivated spores (fis) of b. anthracis to pa elicits total protection a ...200211796596
