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 ...	2002	12442572
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 ...	2002	12442846
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 ...	2002	12442847

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 ...	2002	12457764
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 ...	2002	12458919
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 ...	2002	12459601

biological weapons and bioterrorism preparedness: importance of public-health awareness and international cooperation.	biological weapons and biological terrorism have recently come into focus due to the deliberate release of bacillus anthracis via mail delivered in the usa. since the 1930s, biological weapons have been developed in a number of countries. in 1975, the biological and toxin weapons convention entered into force; this prohibits the use of these weapons and has been signed by a large majority of countries (144). unfortunately, several countries failed to respect this treaty. the soviet union continu ...	2002	12197874
problems associated with potential massive use of antimicrobial agents as prophylaxis or therapy of a bioterrorist attack.	in addition to the direct sanitary damage of a terrorist attack caused by biological weapons, the consequences of the massive stockpiling and consumption of antimicrobial agents in order to treat or prevent the disease under a potential epidemic due to pathogenic bacteria must also be considered. bacillus anthracis, francisella tularensis and yersinia pestis are the bacteria most likely to be used as terrorist weapons. tetracyclines, quinolones and aminoglycoside are the antibiotics of choice ag ...	2002	12197876
[in vitro selection and affinity function of the aptamers to bacillus anthracis spores by selex].	to obtain oligonucleotide aptamers, specifically binding to bacillus anthracis spores, and to find the relationship between the structures and the affinities, and to determine whether the aptamers can be used as a novel molecule for spore detection, a synthetic 35 mer random dna library was subjected to 18 rounds of selection by using selex (systematic evolution of ligands by exponential enrichment) protocol against spores of bacillus anthracis vaccine strain a. 16r. the selected aptamers were c ...	2002	12198569
bacteria as agents of biowarfare. how to proceed when the worst is suspected.	recognition of an increasing incidence of uncommon pneumonias with a high mortality rate, clusters of cases, or a high incidence of pet illnesses or death should alert medical personnel to the possibility of terrorism with bacteriologic agents. prompt reporting of such unusual occurrences to the local health department is of paramount importance for early identification of cases, treatment initiation, and institution of preventive measures.	2002	12198754
cutaneous anthrax: an endemic outbreak in south india.	although human anthrax has become rare, endemic outbreaks still occur in tropical countries, parts of south america and europe. we report 23 cases of cutaneous anthrax due to an endemic outbreak of animal and human anthrax in south india. these patients were admitted to our hospital between july 1998 and july 2001. children outnumbered adults and most of them had lesions on the exposed sites. the majority of patients reported the death of infected animals in the neighbourhood without any direct ...	2002	12200984
a short history of biological warfare.	biological weapons have been used in war from the start of recorded history. this article reviews the history of the subject, including the outbreak of the black death and the use of smallpox against american indians. the new science of microbiology was misused from soon after its start and, despite the 1925 geneva protocol, the japanese experimented extensively on prisoners in china. the allies carried out extensive research during the second world war, notably the united kingdom into anthrax o ...	2002	12201085
macrophage apoptosis by anthrax lethal factor through p38 map kinase inhibition.	the bacterium bacillus anthracis causes the death of macrophages, which may allow it to avoid detection by the innate immune system. we found that b. anthracis lethal factor (lf) selectively induces apoptosis of activated macrophages by cleaving the amino-terminal extension of mitogen-activated protein kinase (mapk) kinases (mkks) that activate p38 mapks. because macrophages that are deficient in transcription factor nuclear factor kappab (nf-kappab) are also sensitive to activation-induced deat ...	2002	12202685
rapid and sensitive identification of pathogenic and apathogenic bacillus anthracis by real-time pcr.	bacillus anthracis spores have been shown to be an efficient biological weapon and their recent use in bioterrorist attacks has demonstrated the need for rapid and specific diagnostics. a taqman real-time pcr for identification of b. anthracis was developed, based on the two plasmids, px01 and px02, both of which are necessary for pathogenicity, as well as on the chromosomally encoded rpob gene. bacteria picked from colonies or pelleted from liquid cultures were directly inoculated into the pcr ...	2002	12204372

bioterrorism--a review.	with the turn of the new millennium, a new kind of warfare has evolved--bioterrorism. after the september 11, 2001 attacks on the world trade center, every country in the world is now living under the shadow of an unknown yet deadly enemy--biological weapons. every individual has suddenly become very vulnerable to this new weapon, which can strike anybody at any time without any warning. it is, therefore, important that we take a close look at this new weapon, so that we can take appropriate mea ...	2002	12206342
gln277 and phe554 residues are involved in thermal inactivation of protective antigen of bacillus anthracis.	protective antigen (pa) is the main component of all the vaccines against anthrax. the currently available vaccines have traces of other proteins that contribute to its reactogenicity. thus, purified pa is recommended for human vaccination. pa loses its biological activity within 48h at 37 degrees c and its thermolability has been a cause of concern as accidental exposure to higher temperatures during transportation or storage could decrease its efficacy. in the present study, we have used prote ...	2002	12207879
