hospital preparedness for chemical and biological incidents in hong kong.the risk of mass exposure to toxic substances has increased steadily during the twentieth century due to the expansion of industry and the deliberate development and use of agents of chemical warfare. although hong kong is considered a relatively safe place, hoax anthrax attacks have occurred since 17 october 2001. people who have been seriously injured by hazardous materials have a greater chance of recovery without complications when appropriate emergency treatments are provided. recognition a ...200212459601
use of anthrax vaccine in response to terrorism: supplemental recommendations of the advisory committee on immunization practices.in december 2000, the advisory committee on immunization practices (acip) released its recommendations for using anthrax vaccine in the united states. because of recent terrorist attacks involving the intentional exposure of u.s. civilians to bacillus anthracis spores and concerns that the current anthrax vaccine supply is limited, acip developed supplemental recommendations on using anthrax vaccine in response to terrorism. these recommendations supplement the previous acip statement in three a ...200212458919
anthrax x-rayed: new opportunities for biodefence.bacillus anthracis, the agent responsible for inhalation anthrax, exerts its lethal effects via the production of anthrax toxin (protective antigen, lethal factor and oedema factor); anthrax kills because the toxin overwhelms the patient before innate host defence systems have a chance to eradicate the invaders. structural studies on these three components provide a starting point for the design of novel drugs to neutralize toxin action, yielding a valuable adjunct to conventional antibiotic tre ...200212457764

diversity among french bacillus anthracis isolates.while outbreaks of animal anthrax zoonoses still regularly occur in france, little is known about the epidemiology links between them. we have used the eight-locus multilocus variable-number tandem repeat analysis typing technique against a collection of 50 bacillus anthracis isolates from france. there were eight distinct genotypes belonging to two dissimilar genetic clusters. regional strain patterns were observed, with the b2 genotypes prevalent in southern france and the a1a genotypes found ...200212454180
broadband 10-300 ghz stimulus-response sensing for chemical and biological entities.by illuminating the sample with a broadband 10-300 ghz stimulus and coherently detecting the response, we obtain reflection and transmission spectra of common powdered substances, and compare them as a starting point for distinguishing concealed threats in envelopes and on personnel. because these samples are irregular and their dielectric properties cannot be modulated, however, the spectral information we obtain is largely qualitative. to show how to gain quantitative information on biological ...200212452568
bile stress response in listeria monocytogenes lo28: adaptation, cross-protection, and identification of genetic loci involved in bile resistance.bile is one of many barriers that listeria monocytogenes must overcome in the human gastrointestinal tract in order to infect and cause disease. we demonstrated that stationary-phase cultures of l. monocytogenes lo28 were able to tolerate concentrations of bovine, porcine, and human bile and bile acids well in excess of those encountered in vivo. strain lo28 was relatively bile resistant compared with other clinical isolates of l. monocytogenes, as well as with listeria innocua, salmonella enter ...200212450822
induction of hepatitis c virus-specific cytotoxic t lymphocytes in mice by immunization with dendritic cells transduced with replication-defective recombinant adenovirus.we studied the potential of dendritic cells (dcs) in priming hepatitis c virus (hcv)-specific cytotoxic t lymphocytes (ctls) in mice. recombinant adenovirus expressing hcv core (adex1sr3st) was employed to express core in dcs. core-specific ctls are effectively elicited by injecting adex1sr3st-transduced dcs, whereas injection of adex1sr3st does not result in effective priming. further, adex1sr3st-transduced dcs more efficiently prime core-specific ctls than adex1sr3st-transduced macrophages, or ...200212450696

public health and national security: the critical role of increased federal support.protecting the public's health historically has been a state and local responsibility. however, the growing threat of bioterrorism has highlighted the importance of a strong public health infrastructure to the nation's homeland security and has focused increased attention on the preparedness of the public health system. as a result, federal public health funding has increased exponentially since the anthrax attacks of late 2001, and congress has passed sweeping new federal legislation intended t ...200212442847
dealing with the dangers of fear: the role of risk communication.among the many lessons of the homeland terrorist attacks of 2001 was that fear has powerful public health implications. people chose to drive instead of flying, thereby raising their risk of injury or death. thousands took broad-spectrum antibiotics to prevent possible anthrax infections, thereby accelerating antimicrobial resistance. such potentially harmful actions were taken by people seeking a sense of safety because they were afraid. this essay argues for greater emphasis on risk communicat ...200212442846
maintaining a vigilance for foreign animal diseases.the incursion of foot-and-mouth disease (fmd) into the united kingdom in february 2001 served as a wakeup call for north american agriculture. as the livestock health crisis in the united kingdom progressed, it became increasingly evident that the united states, canada, and mexico were also susceptible to an incursion of a foreign animal disease. the terrorist attacks of september 11, 2001, and the subsequent anthrax mailings reaffirmed the fact that the united states is vulnerable to an infecti ...200212442572
search for potential vaccine candidate open reading frames in the bacillus anthracis virulence plasmid pxo1: in silico and in vitro screening.a genomic analysis of the bacillus anthracis virulence plasmid pxo1, aimed at identifying potential vaccine candidates and virulence-related genes, was carried out. the 143 previously defined open reading frames (orfs) (r. t. okinaka, k. cloud, o. hampton, a. r. hoffmaster, k. k. hill, p. keim, t. m. koehler, g. lamke, s. kumano, j. mahillon, d. manter, y. martinez, d. ricke, r. svensson, and p. j. jackson, j. bacteriol. 181:6509-6515, 1999) were subjected to extensive sequence similarity search ...200212438358
antimicrobial susceptibilities of diverse bacillus anthracis isolates.a test of 25 genetically diverse isolates of bacillus anthracis was conducted to determine their susceptibility to seven clinically relevant antimicrobial agents. etest strips (ab biodisk, solna, sweden) were used to measure the mics for the isolates. using the national committee for clinical laboratory standards mic breakpoints for staphylococci, three isolates were found to be resistant to penicillin and five were found to be resistant to cefuroxime. the penicillin-resistant isolates were nega ...200212435686
anthrax toxin: a tripartite lethal combination.anthrax is a severe bacterial infection that occurs when bacillus anthracis spores gain access into the body and germinate in macrophages, causing septicemia and toxemia. anthrax toxin is a binary a-b toxin composed of protective antigen (pa), lethal factor (lf), and edema factor (ef). pa mediates the entry of either lf or ef into the cytosol of host cells. lf is a zinc metalloprotease that inactivates mitogen-activated protein kinase kinase inducing cell death, and ef is an adenylyl cyclase imp ...200212435580
in-vitro characterisation of the phagocytosis and fate of anthrax spores in macrophages and the effects of anti-pa antibody.antibodies (abs) to the protective antigen (pa) component of the anthrax toxins have anti-spore as well as anti-toxin activities. anti-pa antisera and purified anti-pa abs enhance the phagocytosis by murine-derived macrophages (mqs) of spores of the ames and sterne strains and retard the germination of extracellular spores in vitro. the fate after phagocytosis of untreated and anti-pa-treated spores was further studied in culture medium that supported phagocytosis without stimulating spore germi ...200212435060
the prophylaxis and treatment of anthrax.bacillus anthracis infection can occur in three forms: cutaneous, gastrointestinal and inhalation depending on the mode of infection. anthrax is a zoonotic disease but the inhalation form can also be used as a biological warfare agent. the recent mail spread outbreak of bioterrorism-related infections in the usa prompted the introduction of specific guidelines by the usa centers for disease control and prevention. postexposure prophylaxis is indicated to prevent inhalational anthrax, and therapy ...200212431866
biological terrorism: understanding the threat, preparation, and medical response.the thought of an outbreak of disease caused by the intentional release of a pathogen or toxin in an american city was alien just 10 years ago. many people believed that biological warfare was only in the military's imagination, perhaps to be faced by soldiers on a far-away battlefield, if at all. the "anthrax letters" and the resulting deaths from inhalation anthrax have changed that perception. the national, state, and local governments in the united states are preparing for what is now called ...200212429949
anthrax, mek and cancer.the mek family of protein kinases plays key roles in regulating cellular responses to mitogens as well as environmental stress. inappropriate activation of these kinases contributes to tumorigenesis. in contrast, anthrax lethal factor, the principal virulence factor of anthrax toxin, has been demonstrated to selectively inactivate meks. in this article we will discuss recent advances in our understanding of molecular aspects of the pathogenesis of anthrax, emphasizing the potential role of mek s ...200212429903
structural analysis and evidence for dynamic emergence of bacillus anthracis s-layer networks.surface layers (s-layers), which form the outermost layers of many bacteria and archaea, consist of protein molecules arranged in two-dimensional crystalline arrays. bacillus anthracis, a gram-positive, spore-forming bacterium, responsible for anthrax, synthesizes two abundant surface proteins: sap and ea1. regulatory studies showed that ea1 and sap appear sequentially at the surface of the parental strain. sap and ea1 can form arrays. the structural parameters of s-layers from mutant strains (e ...200212426331
[bioterrorism: the role of veterinarians in detection and prevention].the fear of terrorist attacks has increased since the events of 11 september 2001 in new york. in the weeks following the terrorist attack, letters containing anthrax spores were received at various locations in the usa. this shows that bioterrorism is possible and that is necessary to be prepared for the potential release of biological agents. such agents can be distributed not only via the air and drinking water but also via household pets. the aim of terrorist attacks, namely, the disruption ...200212425213

collaboration between public health and law enforcement: new paradigms and partnerships for bioterrorism planning and response.the biological attacks with powders containing bacillus anthracis sent through the mail during september and october 2001 led to unprecedented public health and law enforcement investigations, which involved thousands of investigators from federal, state, and local agencies. following recognition of the first cases of anthrax in florida in early october 2001, investigators from the centers for disease control and prevention (cdc) and the federal bureau of investigation (fbi) were mobilized to as ...200212396931
surface sampling methods for bacillus anthracis spore contamination.during an investigation conducted december 17-20, 2001, we collected environmental samples from a u.s. postal facility in washington, d.c., known to be extensively contaminated with bacillus anthracis spores. because methods for collecting and analyzing b. anthracis spores have not yet been validated, our objective was to compare the relative effectiveness of sampling methods used for collecting spores from contaminated surfaces. comparison of wipe, wet and dry swab, and hepa vacuum sock samples ...200212396930
adherence to antimicrobial inhalational anthrax prophylaxis among postal workers, washington, d.c., 2001.in october 2001, two envelopes containing bacillus anthracis spores were processed at the washington, d.c., processing and distribution center of the u.s. postal service; inhalational anthrax developed in four workers at this facility. more than 2,000 workers were advised to complete 60 days of postexposure prophylaxis to prevent inhalational anthrax. interventions to promote adherence were carried out to support workers, and qualitative information was collected to evaluate our interventions. a ...200212396929
anthrax postexposure prophylaxis in postal workers, connecticut, 2001.after inhalational anthrax was diagnosed in a connecticut woman on november 20, 2001, postexposure prophylaxis was recommended for postal workers at the regional mail facility serving the patient's area. although environmental testing at the facility yielded negative results, subsequent testing confirmed the presence of bacillus anthracis. we distributed questionnaires to 100 randomly selected postal workers within 20 days of initial prophylaxis. ninety-four workers obtained antibiotics, 68 of w ...200212396928
antimicrobial postexposure prophylaxis for anthrax: adverse events and adherence.we collected data during postexposure antimicrobial prophylaxis campaigns and from a prophylaxis program evaluation 60 days after start of antimicrobial prophylaxis involving persons from six u.s. sites where bacillus anthracis exposures occurred. adverse events associated with antimicrobial prophylaxis to prevent anthrax were commonly reported, but hospitalizations and serious adverse events as defined by food and drug administration criteria were rare. overall adherence during 60 days of antim ...200212396927
sequencing of 16s rrna gene: a rapid tool for identification of bacillus anthracis.in a bioterrorism event, a tool is needed to rapidly differentiate bacillus anthracis from other closely related spore-forming bacillus species. during the recent outbreak of bioterrorism-associated anthrax, we sequenced the 16s rrna generom these species to evaluate the potential of 16s rrna gene sequencing as a diagnostic tool. we found eight distinct 16s types among all 107 16s rrna gene seqs fuences that differed from each other at 1 to 8 positions (0.06% to 0.5%). all 86 b. anthracis had an ...200212396926
molecular subtyping of bacillus anthracis and the 2001 bioterrorism-associated anthrax outbreak, united states.molecular subtyping of bacillus anthracis played an important role in differentiating and identifying strains during the 2001 bioterrorism-associated outbreak. because b. anthracis has a low level of genetic variability, only a few subtyping methods, with varying reliability, exist. we initially used multiple-locus variable-number tandem repeat analysis (mlva) to subtype 135 b. anthracis isolates associated with the outbreak. all isolates were determined to be of genotype 62, the same as the ame ...200212396925
specific, sensitive, and quantitative enzyme-linked immunosorbent assay for human immunoglobulin g antibodies to anthrax toxin protective antigen.the bioterrorism-associated human anthrax epidemic in the fall of 2001 highlighted the need for a sensitive, reproducible, and specific laboratory test for the confirmatory diagnosis of human anthrax. the centers for disease control and prevention developed, optimized, and rapidly qualified an enzyme-linked immunosorbent assay (elisa) for immunoglobulin g (igg) antibodies to bacillus anthracis protective antigen (pa) in human serum. the qualified elisa had a minimum detection limit of 0.06 micro ...200212396924
laboratory response to anthrax bioterrorism, new york city, 2001.in october 2001, the greater new york city metropolitan area was the scene of a bioterrorism attack. the scale of the public response to this attack was not foreseen and threatened to overwhelm the bioterrorism response laboratory's (btrl) ability to process and test environmental samples. in a joint effort with the centers for disease control and prevention and the cooperation of the department of defense, a massive effort was launched to maintain and sustain the laboratory response and return ...200212396923
coordinated response to reports of possible anthrax contamination, idaho, 2001.in 2001, the intentional release of anthrax spores in the eastern united states increased concern about exposure to anthrax nationwide, and residents of idaho sought assistance. response from state and local agencies was required, increasing the strain on epidemiologists, laboratorians, and communications personnel. in late 2001, idaho's public health communications system handled 133 calls about suspicious powders. for each call, a multiagency bridge call was established, and participants (publ ...200212396922

[prevention of bioterrorism by vaccines].prevention against the weapons of bioterrorists is limited by the multiplicity of agents that could be used. against smallpox, stocks of the classical vaccine must be prepared, but this vaccine is dangerous and we must look for a new and safer vaccine. a vaccine against anthrax is probably possible relatively soon. one may be less optimistic concerning plague, since it is not sure that we could protect against the pulmonary plague, but research in this field is an emergency. the large number of ...200212391900

open-market innovation.companies in many industries are feeling immense pressure to improve their ability to innovate. even in these tough economic times, executives have pushed innovation initiatives to the top of their priority lists, but they know that the best ideas aren't always coming out of their own r&d labs. that's why a growing number of companies are exploring the idea of open-market innovation--an approach that uses tools such as licensing, joint ventures, and strategic alliances to bring the benefits of f ...200212389463
antimicrobial therapy for bacillus anthracis-induced polymicrobial infection in (60)co gamma-irradiated mice.challenge with both nonlethal ionizing radiation and toxigenic bacillus anthracis spores increases the rate of mortality from a mixed bacterial infection. if biological weapons, such as b. anthracis spores, and nuclear weapons were used together, casualties could be more severe than they would be from the use of either weapon alone. we previously discovered that a polymicrobial infection developed in b6d2f(1)/j mice after nonlethal (7-gy) (60)co gamma irradiation and intratracheal challenge with ...200212384351

emergency response planning for anthrax outbreaks in bison herds of northern canada: a balance between policy and science.anthrax outbreaks in northern canada have implications for ongoing recovery efforts for the threatened wood bison and may pose a health risk to humans, other wildlife, and domestic livestock. rwed and wbnp maintain anthrax emergency response plans (aerps) for their respective jurisdictions. an aerp is a pre-planned logistical framework for responding effectively and rapidly to an outbreak so as to minimize spread of the disease, reduce environmental load of spores available for future outbreaks, ...200212381599
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
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
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
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

delivery of nucleic acid into mammalian cells by anthrax toxin.gene delivery vehicles based on receptor-mediated endocytosis offer an attractive long-term solution as they might overcome the limitations of toxicity and cargo capacity inherent to many viral gene delivery systems. the protective antigen component of anthrax toxin bind to specific receptors and deliver lethal factor or edema factor into the cytosol of mammalian cells. the n-terminal 254 amino acids of lf (lf(1-254)) binds to pa and, when fused to heterologous proteins, delivers such proteins i ...200212372402
anthrax fusion protein therapy of cancer.most patients with cancer are treated with chemotherapy but die from progressive disease or toxicities of therapy. current chemotherapy regimens primarily use cytotoxic drugs which damage cell dna or impair cell proliferation in both malignant and normal tissues. after several treatment courses, the patients' tumor cells often overexpress multi-drug resistance genes which prevent further tumor cytoreduction. novel agents which can kill such resistant tumor cells are needed. one such class of age ...200212370003
on the front lines: family physicians' preparedness for bioterrorism.the events of september 11, 2001, and the nation's recent experience with anthrax assaults made bioterrorism preparedness a national priority. because primary care physicians are among the sentinel responders to bioterrorist attacks, we sought to determine family physicians' beliefs about their preparedness for such an attack.200212366891
