structure of two iron-binding proteins from bacillus anthracis.	bacillus anthracis is currently under intense investigation due to its primary importance as a human pathogen. particularly important is the development of novel anti-anthrax vaccines, devoid of the current side effects. a novel class of immunogenic bacterial proteins consists of dodecamers homologous to the dna-binding protein of escherichia coli (dps). two dps homologous genes are present in the b. anthracis genome. the crystal structures of these two proteins (dlp-1 and dlp-2) have been deter ...	2002	11836250
anthrax: a primary care physician's perspective.	anthrax is a disease caused by bacillus anthracis, a gram-positive, aerobic, spore-forming rod. it is also used as a biological weapon. the primary care physician will be the public's first line of defense in the event of a widespread anthrax exposure and will play a crucial role providing postexposure prophylaxis. understanding the disease process will allow the primary care physician to play an essential role in protecting and educating the public. accurate diagnosis and quick treatment will s ...	2002	11837339
symptoms associated with anthrax exposure: suspected "aborted" anthrax.	anthrax is a naturally occurring organism with a low incidence of infection. there are no known cases of human-to-human transmission. bioterrorism-related anthrax in the united states has been seen in three high-risk groups: (1) postal workers, (2) politicians and their staffs, and (3) the press. it appears as though the bioterrorism-related anthrax cases of fall 2001 have been transmitted through the us postal service. the authors present a case in which a person at high risk for anthrax exposu ...	2002	11837340

amino acid- and purine ribonucleoside-induced germination of bacillus anthracis deltasterne endospores: gers mediates responses to aromatic ring structures.	specific combinations of amino acids or purine ribonucleosides and amino acids are required for efficient germination of endospores of bacillus anthracis deltasterne, a plasmidless strain, at ligand concentrations in the low-micromolar range. the amino acid l-alanine was the only independent germinant in b. anthracis and then only at concentrations of >10 mm. inosine and l-alanine both play major roles as cogerminants with several other amino acids acting as efficient cogerminants (his, pro, trp ...	2002	11844758
anthrax vaccine: immunogenicity and safety of a dose-reduction, route-change comparison study in humans.	anthrax vaccine adsorbed (ava), an effective countermeasure against anthrax, is administered as six subcutaneous (sq) doses over 18 months. to optimize the vaccination schedule and route of administration, we performed a prospective pilot study comparing the use of fewer ava doses administered intramuscularly (im) or sq with the current schedule and route. we enrolled 173 volunteers, randomized to seven groups, who were given ava once im or sq; two doses, 2 or 4 weeks apart, im or sq; or six dos ...	2002	11818160
anthrax vaccine efficacy in golden syrian hamsters.	the efficacy of a licensed human anthrax vaccine (anthrax vaccine adsorbed, ava) was tested in golden syrian hamsters against a virulent bacillus anthracis spore challenge. groups of golden syrian hamsters were vaccinated at either 0 and 4 weeks or 0, 4 and 8 weeks, then challenged subcutaneously (s.c.) at 10 weeks with spores of various b. anthracis isolates. although elisa and toxin neutralization assays demonstrated high titers, none of the ava-vaccinated hamsters were protected from challeng ...	2002	11818161
inhalational anthrax after bioterrorism exposure: spectrum of imaging findings in two surviving patients.	the radiographic and computed tomographic (ct) findings in two patients with documented inhalational anthrax resulting from bioterrorism exposure are presented. chest radiographs demonstrated mediastinal widening, adenopathy, pleural effusions, and air-space disease. chest ct images revealed enlarged hyperattenuating mediastinal and hilar lymph nodes and edema of mediastinal fat. chest ct findings are helpful for making the initial diagnosis. to the authors' knowledge, the spectrum and follow-up ...	2002	11818592
anthrax: ent manifestations and current concepts.	in light of recent events, anthrax has once again taken center stage in the world of science and the world in which we live. because patients with anthrax may initially present to otolaryngology clinics, it is important for the otolaryngologist to know how to diagnose and treat this entity. this article will present current information on epidemiology, microbiology, pathogenesis/clinical manifestations, diagnosis, and treatment with a particular interest in the head and neck region.	2002	11821758

fatal inhalational anthrax with unknown source of exposure in a 61-year-old woman in new york city.	a 61-year-old woman who was a new york city hospital employee developed fatal inhalational anthrax, but with an unknown source of anthrax exposure. the patient presented with shortness of breath, malaise, and cough that had developed 3 days prior to admission. within hours of presentation, she developed respiratory failure and septic shock and required mechanical ventilation and vasopressor therapy. spiral contrast-enhanced computed tomography of the chest demonstrated large bilateral pleural ef ...	2002	11851577
fatal inhalational anthrax in a 94-year-old connecticut woman.	we describe the 11th case of bioterrorism-related inhalational anthrax reported in the united states. the presenting clinical features of this 94-year-old woman were subtle and nondistinctive. the diagnosis was recognized because blood cultures were obtained prior to administration of antibiotics, emphasizing the importance of this diagnostic test in evaluating ill patients who have been exposed to bacillus anthracis. the patient's clinical course was characterized by progression of respiratory ...	2002	11851578
cutaneous anthrax associated with microangiopathic hemolytic anemia and coagulopathy in a 7-month-old infant.	a 7-month-old infant with cutaneous anthrax developed severe systemic illness despite early treatment with antibiotics. the infant displayed severe microangiopathic hemolytic anemia with renal involvement, coagulopathy, and hyponatremia. these findings are unusual with cutaneous anthrax, but have been described in illness resulting from spider toxin and may delay correct diagnosis. the systemic manifestations of the disease persisted for nearly a month despite corticosteroid therapy, but resolve ...	2002	11851579

vaccines for adults in an age of terrorism.	vaccines are an effective, safe, and relatively inexpensive means of preventing infection; thus, they are important tools for fighting biological terrorism. two diseases, anthrax and smallpox, for which vaccines are not available to the general public are discussed. three other vaccines--tetanus toxoid, influenza vaccine, and hepatitis b vaccine--generally recommended for adults, may be in short supply as a result of recent acts of terrorism.	2002	11852666
bioterrorism: a primer for 2002.	the often anticipated, sometimes dismissed, threat of biological terrorism became a reality in the united states in the fall of 2001 with cases of cutaneous and inhalation anthrax. as the public health sector is rapidly focusing on enhancing awareness and preparedness, this overview is intended as a primer for clinicians. the more probable events, their most prominent characteristics, and currently available management strategies are summarized. the biowarfare characteristics of plague, tularemi ...	2002	11852669
biological warfare: implications for antimicrobial use.	biological warfare is intended to incapacitate a large number of individuals at a single exposure, creating epidemic-type disease, death, and social chaos. the organisms with potential for immediate use as bacteriologic weapons are bacillus anthracis, brucella melitensis, yersinia pestis, and vibrio cholera, all necessitating antibiotic therapy for a cure. it is reasonable, therefore, to assume that a biological attack, or even a hoax, would requiure thousands of individuals over a large area to ...	2002	11853654

uncoupling of the cholera toxin-g(m1) ganglioside receptor complex from endocytosis, retrograde golgi trafficking, and downstream signal transduction by depletion of membrane cholesterol.	to induce toxicity, cholera toxin (ct) must first bind ganglioside g(m1) at the plasma membrane, enter the cell by endocytosis, and then traffic retrograde into the endoplasmic reticulum. we recently proposed that g(m1) provides the sorting motif necessary for retrograde trafficking into the biosynthetic/secretory pathway of host cells, and that such trafficking depends on association with lipid rafts and lipid raft function. to test this idea, we examined whether ct action in human intestinal t ...	2002	11859071

array-based electrical detection of dna with nanoparticle probes.	a dna array detection method is reported in which the binding of oligonucleotides functionalized with gold nanoparticles leads to conductivity changes associated with target-probe binding events. the binding events localize gold nanoparticles in an electrode gap; silver deposition facilitated by these nanoparticles bridges the gap and leads to readily measurable conductivity changes. an unusual salt concentration-dependent hybridization behavior associated with these nanoparticle probes was expl ...	2002	11859188
the microbiology laboratory's role in response to bioterrorism.	bioterrorism has existed since before the 14th century; however, the specter of such an attack is much greater today than ever before. technical expertise in microbiology and molecular testing, combined with the rapidity of worldwide air travel, has ensured that no geographic area would be untouched in a widespread attack. clinical microbiology laboratories will play a pivotal role in the detection of attacks involving weapons of mass destruction.	2002	11860302
traditions, anthrax, and children.	anthrax is sporadically seen in turkey, especially among people who live in rural areas and who come in contact with animals. two siblings with cutaneous anthrax are described in this report. a week before their admission to the hospital, contaminated cow's blood was smeared on their foreheads as part of a traditional ritual. both children were successfully treated with crystalline penicillin. in developing countries, traditions such as blood smearing may be an important factor in the transmissi ...	2002	11860568
the space race and biodefense: lessons from nasa about big science and the role of medical informatics.	the events that followed the launch of sputnik on oct 4, 1957, provide a metaphor for the events that are following the first bioterroristic case of pulmonary anthrax in the united states. this paper uses that metaphor to elucidate the nature of the task ahead and to suggest questions such as, can the goals of the biodefense effort be formulated as concisely and concretely as the goal of the space program? can we measure success in biodefense as we did for the space project? what are the existin ...	2002	11861624

discovery of the anthrax toxin: the beginning of studies of virulence determinants regulated in vivo.	anthrax kills many animal species. it was used to prove koch's postulates in 1876. soon after that the classical bacterial toxins were produced in vitro, but up to 1950, a lethal toxin had not been demonstrated in either anthrax bacilli or filtrates from laboratory cultures. the cause of death had been an enigma for seventy years. during the 1950's, a toxin was recognized by examining bacteria and their products obtained from guinea pigs dying of anthrax. the toxin was found in their plasma and ...	2002	11890538
tnf receptor 1, il-1 receptor, and inos genetic knockout mice are not protected from anthrax infection.	anthrax produces at least two toxins that cause an intense systemic inflammatory response, edema, shock, and eventually death. the relative contributions of various elements of the immune response to mortality and course of disease progression are poorly understood. we hypothesized that knockout mice missing components of the immune system will have an altered response to infection. parent strain mice and knockouts were challenged with ld95 of anthrax spores (5 x 10(6)) administered subcutaneous ...	2002	11890668
