RESUMO
We aimed to develop an efficient detection platform that can identify a larger number of suspicious samples in a single test, saving time, manpower, and material costs, and providing vital support to the public health system in coping with the current challenging and dynamic bioterrorism threat landscape, particularly in regions of turmoil and conflict. We have successfully developed a high-throughput, multitarget fluorescent array detection platform by effectively combining integrating multiprobe amplification (MPA) with melting curve analysis. Specifically, we have established reliable laboratory testing methods for eight highly pathogenic bacteria, including Bacillus anthracis, Yersinia pestis, Brucella spp., Burkholderia pseudomallei, Francisella tularensis, Vibrio cholerae, Salmonella typhi, and Staphylococcus aureus. Our method achieves sensitive and specific simultaneous detection of eight target bacteria in one well by optimizing the reaction conditions of MPA. In the assessment of 192 simulated environmental samples, both positive and negative coincidence rates were 100.00%. Among 48 simulated clinical samples, the positive coincidence rate reached 97.73%, while maintaining a perfect negative coincidence rate of 100.00%. Moreover, the detection platform holds immense potential for attaining a more comprehensive bioterrorism screening, and its high cost-effectiveness enables the provision of diverse and adaptable diagnostic methods for public health quarantine in underdeveloped countries and regions.

Historically, biological agents have been used to target various populations. One of the earliest examples could be the catastrophic effect of smallpox in Australia in the eighteenth century (as alleged by some historians). Modern biological techniques can be used to both create or provide protection against various agents of biological warfare. Any microorganism (viruses, bacteria, and fungi) or its toxins can be used as biological agents. Minnesota Department of Health has listed Smallpox (variola major) as a category A bioterrorism agent, even though it has been eradicated in 1980 through an extensive vaccination campaign. Category A agents are considered the highest risk to public health. Laboratory-associated outbreaks of poxviruses could cause unprecedented occupational hazards. Only two WHO-approved BSL-4 facilities in the United States and Russia are allowed to perform research on the variola virus. So, poxviruses present themselves as a classical case of a dual-use dilemma, since research with them can be used for both beneficial and harmful purposes. Although the importance of ethics in scientific research requires no further elaboration, ethical norms assume greater significance during experimentation with poxviruses. In this chapter, we will update the readers on the sensitive nature of conducting research with poxviruses, and how these viruses can be a source of potential biological weapons. Finally, specified ethical guidelines are explored to ensure safe research practices in virology.

AIM: Evaluate the efficacy of sponge wipe sampling at recovering potential bacterial surrogates for Category A and B non-spore-forming bacterial bioterrorism agents from hard, nonporous surfaces. METHODS: A literature survey identified seven nonpathogenic bacteria as potential surrogates for selected Category A and B non-spore-forming bacterial agents. Small (2 × 4 cm) and large (35.6 × 35.6 cm) coupons made from either stainless steel, plastic, or glass, were inoculated and utilized to assess persistence and surface sampling efficiency, respectively. Three commercially available premoistened sponge wipes (3M™, Sani-Stick®, and Solar-Cult®) were evaluated. RESULTS: Mean recoveries from persistence testing indicated that three microorganisms (Yersinia ruckeri, Escherichia coli, and Serratia marcescens) demonstrated sufficient persistence across all tested material types. Sampling of large inoculated (≥107 CFU per sample) coupons resulted in mean recoveries ranging from 6.6 to 3.4 Log10 CFU per sample. Mean recoveries for the Solar-Cult®, 3M™ sponge wipes, and Sani-Sticks® across all test organisms and all material types were ≥5.7, ≥3.7, and ≥3.4 Log10 CFU per sample, respectively. Mean recoveries for glass, stainless steel, and ABS plastic across all test organisms and all sponge types were ≥3.8, ≥3.7, and ≥3.4 Log10 CFU per sample, respectively. CONCLUSIONS: Recovery results suggest that sponge wipe sampling can effectively be used to recover non-spore-forming bacterial cells from hard, nonporous surfaces such as stainless steel, ABS plastic, and glass.

In the wake of the COVID-19 pandemic, the United States is actively reshaping parts of its national security enterprise. This article explores the underlying politics, with a specific interest in the context of biosecurity, biodefense, and bioterrorism strategy, programs, and response, as the United States responds to the most significant outbreak of an emerging infectious disease in over a century. How the implicit or tacit failure to recognize the political will and political decision-making connected to warfare and conflict for biological weapons programs in these trends is explored. Securitization of public health has been a focus of the literature over the past half century. This recent trend may represent something of an inverse: an attempt to treat national security interests as public health problems. A hypothesis is that the most significant underrecognized problem associated with COVID-19 is disinformation and the weakening of confidence in institutions, including governments, and how adversaries may exploit that blind spot.

ObjectivesãBioterrorism is a disease in which the attacks can be covert and latent, take time to manifest, and, when discovered, can result in large outbreaks. When detected, they can become large-scale outbreaks. Therefore, preparedness is essential for early detection and response for damage mitigation. Although public health nurses (PHNs) of public health centers are responsible for detecting and dealing with bioterrorism, their preparation status is not clear. Therefore, this study aimed to elucidate the status of training experience, knowledge, and awareness of bioterrorism among PHNs working in public health centers' infectious disease control departments in Japan's metropolitan areas.MethodsãThis was a cross-sectional, descriptive study. The participants were PHNs in the infectious disease control departments of 88 public health centers in Tokyo and its three neighboring prefectures. This are densely populated metropolitan areas with many mass gathering events and a high probability of bioterrorism. An anonymous, self-administered questionnaire survey was conducted by mail in 2019. Two PHNs per location were surveyed regarding their attributes, training experience, knowledge, and perceptions.ResultsãWe received 71 responses (40.3%). A total of 10 (14.1%) PHNs reported having experience with bioterrorism training in the workplace. Regarding the knowledge of the four infectious diseases with a high probability of bioterrorism, more than 95% of the respondents answered they had heard of them. However, few were aware of related treatments or terrorist responses. Although survey respondents were aware of the seriousness of bioterrorism and the effectiveness of preparedness, they did not have sufficient opportunity or time to have training. They tended to be less confident in their response and were willing to have training.ConclusionãPHNs who responded to this survey do not have sufficient training experience, knowledge, opportunities, and time for bioterrorism training, and establishing a training system to improve bioterrorism preparedness is a challenge. It will be necessary for PHN students to learn about the existence of bioterrorism. Further, PHNs in public health centers need to be trained at least once using online services, including brushing up on information as needed. Based on the lessons learned from the coronavirus disease 2019 pandemic, health centers will formulate a Health Crisis Management Plan. This will be effective in fiscal 2024, and we believe that it is essential that preparedness against bioterrorism be a part of this plan.

The coronavirus disease 2019 pandemic accelerated developments in biotechnology that underpin infection science. These advances present an opportunity to refresh the microbial forensic toolkit. Integration of novel analytical techniques with established forensic methods will speed up acquisition of evidence and better support lines of enquiry. A critical part of any such investigation is demonstration of a robust causal relationship and attribution of responsibility for an incident. In the wider context of a formal investigation into agency, motivation and intent, the quick and efficient assembly of microbiological evidence sets the tone and tempo of the entire investigation. Integration of established and novel analytical techniques from infection science into a systematic approach to microbial forensics will therefore ensure that major perspectives are correctly used to frame and shape the evidence into a clear narrative, while recognizing that forensic hypothesis generation, testing and refinement comprise an iterative process. Development of multidisciplinary training exercises that use this approach will enable translation into practice and efficient implementation when the need arises.

BACKGROUND: Smallpox was a major cause of human mortality until its eradication, but the threat of orthopox viruses has not disappeared. Since the eradication of smallpox and the cessation of the related vaccination campaigns, the threat has been growing, as evidenced by the currently ongoing worldwide Mpox outbreak. In addition to threats of an evolving Mpox, we must also be aware of a myriad of other threats that remain. Many countries still lack biosecurity regulations reflecting the recent technological advances, and the threat of bioterrorism remains ever present. Reconstruction of smallpox is a distinct possibility, as are other scenarios whereby other orthopox viruses may be made more fit for transmission in humans. OBJECTIVES: To outline and discuss potential biosafety and biosecurity threats posed by orthopox viruses. SOURCES: Published scientific literature, news articles, and international agreements. CONTENT AND IMPLICATIONS: It would be wise to take steps to mitigate these threats now. Vaccination campaigns should be considered in areas with frequent orthopox outbreaks, and more efforts must be made to put a final end to the Mpox outbreak. In many countries, national biosafety and biosecurity regulations may need to be revised and strengthened to better reflect the threats posed by new technologies, including controls on synthesis of smallpox sequences. Furthermore, more international cooperation and aid is needed. The present global Mpox outbreak could likely have been prevented had areas where Mpox is endemic not been neglected. Future outbreaks could be much worse.

BACKGROUND: To respond to unstable international security and the outbreak of new infectious diseases, clinical nurses should be equipped with bioterrorism response competencies. OBJECTIVES: This study developed a mobile-based bioterrorism response program for clinical nurses and examined its effectiveness on their knowledge of bioterrorism, attitude toward bioterrorism response, and bioterrorism response competencies. DESIGN: A quasi-experimental study design was used. SETTING: General or tertiary general hospitals in South Korea were considered. PARTICIPANTS: Participants were 45 clinical nurses (23 in the experimental group and 22 in the control). METHODS: The mobile-based bioterrorism response program was conducted over three weeks in 10 sessions (total of 300 min). The knowledge of bioterrorism, attitude toward bioterrorism response, and bioterrorism response competencies were compared between two groups using paired t-test, and Wilcoxon signed ranks test. Satisfaction with the program was measured in the experimental group. RESULTS: Upon completion of the mobile-based bioterrorism response program, the experimental group showed significant increases in knowledge of bioterrorism, attitude toward bioterrorism response, and bioterrorism response competencies. CONCLUSIONS: The mobile-based bioterrorism response program is expected to contribute to better preparedness for bioterrorism response systems in clinical practice. In addition, this program is expected to be of valuable use in bioterrorism education for nursing students as well as other healthcare professionals involved in bioterrorism response.

The current research aimed to analyze the history of bioterrorism in antiquity and to adapt the data to modern medical knowledge. To this end, a thorough evaluation of the literature related to the ancient history of bioterrorism and modern data was done using the Web of Sciences, Science Direct, Scopus, PubMed, and Google Scholar. Results showed that knowledge of bioterrorism has existed since antiquity in different civilizations. Biological and toxicological agents were used as an instrument of legal execution, as a warfare tool in battles, or to eliminate political rivals across nations. Ancient people researched bioterrorism to apply it against enemies and at the same time provide countermeasures in favor of themselves and allies. Despite the existence of the principles of bioterrorism since ancient times, adaptation of the data to modern research can assist in planning countermeasure efforts, preventive actions, and treatments in the framework of modern counterterrorism medicine.

INTRODUCTION: Nuclear reactor incidents and bioterrorism outbreaks are concerning public health disasters. Little is known about US Food and Drug Administration (FDA)-approved agents that can mitigate consequences of these events. We review FDA data supporting regulatory approvals of these agents. AREAS COVERED: We reviewed pharmaceutical products approved to treat Hematopoietic Acute Radiation Syndrome (H-ARS) and to treat or prevent pulmonary infections following Bacillus anthracis (anthrax) exposure. Four drugs were approved for H-ARS: granulocyte-colony stimulating factor (G-CSF), granulocyte/macrophage colony stimulating factor, pegylated G-CSF, and romiplostim. For bioterrorism-associated anthrax, the FDA approved five antibiotics (doxycycline, penicillin-G, levofloxacin, moxifloxacin, and ciprofloxacin), two monoclonal antibodies (obiltoxaximab and raxibacumab), one polyclonal antitoxin (Anthrax Immune Globulin Intravenous) and two vaccines (Anthrax Vaccine Adsorbed and Anthrax Vaccine Adsorbed with an adjuvant). A national stockpile system ensures that communities have ready access to these agents. Our literature search was based on data included in drugs@FDA (2001-2023). EXPERT OPINION: Two potential mass public health disasters are aerosolized anthrax dissemination and radiological incidents. Five agents authorized for anthrax emergencies only have FDA approval for this indication, five antibiotics have FDA approvals as antibiotics for common infections and for bacillus anthrax, and four agents have regulatory approvals for supportive care for cancer and for radiological incidents.

We provide incidences (cases/10 million persons) in the Netherlands during 2009-2019 for pathogens listed as potential bioterrorism agents. We included pathogens from the highest categories of the European Medicines Agency or the US Centers for Disease Control and Prevention. Notifiable diseases and recently published data were used to calculate the average annual incidence. Coxiella burnetii had the highest incidence because of a Q fever epidemic during 2007-2010. Incidence then decreased to 10.8 cases/. Pathogens with an incidence >1 were Brucella spp. (2.5 cases), Francisella tularensis (1.3 cases), and Burkholderia pseudomallei (1.1 cases). Pathogens with an incidence <1 were hemorrhagic fever viruses (0.3 cases), Clostridium botulinum (0.2 cases), and Bacillus anthracis (0.1 cases). Variola major and Yersinia pestis were absent. The generally low incidences make it unlikely that ill-meaning persons can isolate these pathogens from natural sources in the Netherlands. However, the pathogens are stored in laboratories, underscoring the need for biosecurity measures.
