In October 2015, a bipartisan study panel on biodefense, A National Blueprint for Biodefense made thirty-three recommendations to advance biopreparedness in the United States. A year later in December 2016, a report titled, The Biodefense Indicators: One Year Later, Events Outpacing Efforts to Defend the Nation (The “One Year Later Report”) provides compelling evidence that much work remains to be done. Within the thirty-three recommendations in the original National Blueprint for Biodefense, forty-six specific action items were designated for execution as a short-term action within a year or less. Among these, twenty-seven were not addressed by any action during the past year. Seventeen received partial action while only two of these were deemed completed. Continuing efforts to protect our populations from biological threats is imperative and warrant immediate constructive short-term action.
2015年10月,一个关于生物防御的两党研究小组《国家生物防御蓝图》提出了33项建议,以推进美国的生物防御。一年后的2016年12月,一份题为《生物防御指标:一年后,事件超过保卫国家的努力》(《一年后报告》)的报告提供了令人信服的证据,表明仍有许多工作要做。在最初的《国家生物防御蓝图》中的33项建议中,有46项具体行动项目被指定为在一年或更短时间内执行的短期行动。在这些问题中,有27个问题在过去一年中没有采取任何行动加以解决。17个得到部分行动,其中只有两个被认为已完成。继续努力保护我们的人民免受生物威胁是必要的,需要立即采取建设性的短期行动。

Securing the Biowatch Web Portal 保护生物观察网站门户
Pub Date : 2017-01-27 DOI: 10.4172/2157-2526.1000153

The Department of Homeland Security (DHS) BioWatch program is the only nationwide early detection system to provide warning, and situational awareness, to DHS decision makers, in the event of a bioterrorism attack. The BioWatch Web Portal is the means by which DHS collects, analyzes, and shares, bio-threat information amongst federal, state, and local jurisdictions. Integrity and confidentiality of the information collected by the portal is paramount to that decision makers make decisions on reliable, and accurate information. Just as important is the appropriate safeguarding of such information so that a malicious actor is denied sufficient detail as to the methods, materials, and false negative rates that would enable such an actor to spoof the system or circumvent detection. An internal and external assessment analysis of the BioWatch Web Portal revealed that sufficient security controls to mitigate risk posed to the integrity and confidentiality of information processed by the BioWatch Web Portal was not in place. Furthermore, it was discovered that security countermeasures were not in place to detect a possible breach. In addition, it was discovered that the information processes information at the SECRET level security classification.
美国国土安全部(DHS)生物监视计划是唯一一个全国性的早期检测系统,可以在发生生物恐怖袭击时向DHS决策者提供预警和态势感知。生物观察门户网站是国土安全部在联邦、州和地方司法管辖区之间收集、分析和共享生物威胁信息的手段。门户收集的信息的完整性和机密性对于决策者根据可靠和准确的信息做出决策至关重要。同样重要的是,对这些信息进行适当的保护,以使恶意行为者无法充分了解使此类行为者能够欺骗系统或规避检测的方法、材料和假阴性率的细节。生物观察门户网站的内部和外部评估分析显示,没有足够的安全控制措施来减轻生物观察门户网站处理的信息的完整性和保密性所带来的风险。此外,还发现没有采取安全对策来检测可能的违规行为。此外,还发现该信息处理的信息为SECRET级安全分类。

Introduction: Biological threats are one of the greatest dangers that threaten national security of different countries. Ebola haemorrhagic fever is one of these threats and there is no guideline that helps us to deal with suspected cases in Emergency Medical Services (EMS) in Iran. Objective: This study has been conducted to develop native guidelines reaction, based on world protocols, in Emergency Medical Services of the Islamic Republic of Iran in facing Ebola. Method: This study is considered literature review and was conducted by library studies. At first we started by identifying the domestic and international organizations and centres then visiting the sites and information resources available, we searched for proper keywords then we collected and localized all guidelines and instructions about dealing with Ebola. In the end a comprehensive chart was provided to determine the way of facing and transporting patients suspected with Ebola by care and pre-hospital emergency personnel. Discussion: Based on general facts, overview guidelines should be useful to establish native compilation that includes planning and preparation, screening (telephone triage) patients, special assessment and transmit team via telephone calls, making necessary coordination with other organizations and units within and outside the organization, preparation for patient transport, preparation and carrying out some activities after transporting and the process of evaluation after transferring patients. Conclusion: To succeed in facing similar diseases, considering the need to write native guidelines for each country according to the generalities mentioned, all organizations and institutions involved, should start working in concert with each other and the instructions and practice manoeuvres should be performed again and again to review and fix bugs.
生物威胁是威胁各国国家安全的最大危险之一。埃博拉出血热是这些威胁之一,伊朗没有指导方针帮助我们处理紧急医疗服务部门的疑似病例。目的:本研究旨在根据世界协议制定伊朗伊斯兰共和国紧急医疗服务部门应对埃博拉病毒的本地指导方针。方法:本研究采用文献复习法和图书馆研究法。首先,我们确定了国内和国际组织和中心,然后访问了可用的网站和信息资源,我们搜索了适当的关键词,然后收集并本地化了有关应对埃博拉的所有指导方针和说明。最后提供了一份综合图表,以确定护理人员和院前急救人员面对和运送埃博拉疑似患者的方式。讨论:基于一般事实,总览指南应该有助于建立本地编制,包括计划和准备,筛选(电话分诊)患者,通过电话进行特殊评估和转运小组,与组织内外其他组织和单位进行必要的协调,患者转运准备,转运后的准备和开展一些活动以及转运后的评估过程。结论:为了成功应对类似疾病,考虑到需要根据所提到的一般性原则为每个国家编写本地指南,所有有关组织和机构应开始相互协作,并应一次又一次地执行指导和实践演习,以审查和修复错误。

Arboterrorism, the weaponisation and use of arthropod vectors carrying pathogenic microbes, is a worrying possibility in an age of rapidly accelerating biology. Historically, arboterrorism has attracted minimal research and the probability of such attacks occurring has been unclear. For the first time the logistics of such attacks are discussed along with potential vectors and pathogens. A novel biodefence strategy against arboterrorism is also proposed.

Pathogen adherence to a host cell is one of the first essential steps for establishing invasion, colonization and release of virulence factors such as toxins. Understanding the mechanisms used by pathogens and toxins to adhere and invade human cells could lead to the development of new strategies for preventing and controlling the spread of infectious diseases. This review focuses on carbohydrate-lectin interactions utilized by selected biothreat agents to bind and invade host cells. The principle of using anti-adhesion molecules, based on glycobiology research, has already been shown to be effective in the treatment of influenza. Therefore, translating the same principle to other biothreat agents that mediate invasion of a host cell through carbohydrate-lectin mechanisms is a very promising strategy. We investigate recent literature to highlight the latest developments in the field of glycobiology focused on inhibiting the initial steps of pathogen invasion, with examples for bacteria, toxin and virus interactions. The successful glycomimetics and glycoconjugates represent strategies for interruption of adhesion by single molecules and in multivalent systems against uropathogenic E. coli, several toxins (Shiga-like, cholera, botulinum) and well-known or emerging viruses (influenza, HIV, Ebola, and Zika). This review provides promising directions and prophylactic as well as therapeutic potential of anti-adhesive strategies against selected biothreat targets.
病原体粘附于宿主细胞是建立入侵、定植和释放毒力因子(如毒素)的首要步骤之一。了解病原体和毒素粘附和侵入人体细胞的机制可能会导致制定预防和控制传染病传播的新战略。本文综述了碳水化合物-凝集素相互作用的选择生物威胁剂利用结合和入侵宿主细胞。基于糖生物学研究,使用抗黏附分子的原理已被证明对治疗流感有效。因此,将相同的原理转化为通过碳水化合物-凝集素机制介导宿主细胞入侵的其他生物威胁剂是一种非常有前途的策略。我们研究了最近的文献,以突出糖生物学领域的最新发展,重点是抑制病原体入侵的初始步骤,并举例说明细菌、毒素和病毒的相互作用。成功的糖仿制品和糖缀合物代表了单分子和多价系统中针对尿路致病性大肠杆菌、几种毒素(志贺样、霍乱、肉毒杆菌)和已知或新出现的病毒(流感、艾滋病毒、埃博拉和寨卡病毒)的粘附中断策略。本文综述了针对特定生物威胁靶点的抗黏附策略的预防和治疗潜力。

Opportunities and Challenges of Therapeutic Monoclonal Antibodies as Medical Countermeasures for Biodefense 治疗性单克隆抗体作为生物防御医学对策的机遇与挑战

Antibodies, naturally produced in the body as part of the immune response to infectious agents, can also be introduced artificially to treat infectious diseases. Advances in biotechnology in the last decades have made human or humanized monoclonal antibodies (mAbs) as therapeutics possible. These therapeutic mAbs currently enjoy unprecedented success and recognition of their potential. Unlike vaccines, therapeutic mAbs can confer instant and consistent protection against bio-threat agents when administered regardless of the recipient’s immune status. Therapeutic mAbs can be administered in higher levels than those elicited by vaccines, and thus provide a higher level of protection or treatment that is necessary in a biological attack where people are exposed to a higher exposure of agent concentration than that found in nature. Furthermore, therapeutic mAbs have substantial advantages over antimicrobial drugs, such as high specificity, low systemic toxicity, relatively long half-life, and no concerns over disrupting the body’s microbiome. Therapeutic mAbs can be used for both pre- and post-exposure protection; therefore, they have great value as effective medical countermeasures (MedCMs) against bio-threat agents. However, there are still some challenges to be overcome before therapeutic mAbs become ideal MedCMs against bio-threat agents. In this review, both opportunities and challenges in development of therapeutic mAbs are discussed.
体内自然产生的抗体,作为对传染病的免疫反应的一部分,也可以人工引入来治疗传染病。近几十年来生物技术的进步使人或人源化单克隆抗体(mab)成为治疗手段成为可能。这些治疗性单克隆抗体目前取得了前所未有的成功,其潜力得到了认可。与疫苗不同的是,治疗性单克隆抗体无论接受者的免疫状态如何,都能提供即时和一致的生物威胁剂保护。治疗性单克隆抗体的剂量可以比疫苗产生的剂量高,因此在人们暴露于比自然界中暴露的药剂浓度更高的生物攻击中,提供必要的更高水平的保护或治疗。此外,治疗性单克隆抗体与抗菌药物相比具有显著优势,如高特异性、低全身毒性、相对较长的半衰期,并且不担心破坏人体微生物群。治疗性单克隆抗体可用于暴露前和暴露后保护;因此,它们作为对抗生物威胁剂的有效医疗对策(MedCMs)具有重要价值。然而,在治疗性单克隆抗体成为理想的抗生物威胁药物之前,仍有一些挑战需要克服。在这篇综述中,讨论了治疗性单克隆抗体发展的机遇和挑战。

Parasitic worms, more commonly known as helminths, have a significant effect on global human health. However, this group of pathogens has been overlooked by bioterrorism researchers and analysts as possible agents who may be weaponised and deployed by terrorist groups or rogue states. For the first time, the dangers posed by these agents are highlighted along with the potential of the group for weaponisation. The first biodefense strategies against helminthic bioweapons are also proposed.

Bacillus anthracis, the causative agent of anthrax is considered as the most important biological warfare agent. This Gram-positive, spore forming bacterium has three modes of infection i.e. cutaneous, inhalational and gastrointestinal in human. The principal virulence factors of this bacterium consist of an anti-phagocytic capsule composed of poly-D-glutamic acid and a secreted tripartite bacterial toxin composed of protective antigen (PA), lethal factor (LF) and edema factor (EF). PA is the pivotal protein of the anthrax toxin complex and immune response to PA is central to protection against B. anthracis. In this study, overlapping portions of four different domains of PA were cloned and expressed. The recombinant proteins were purified and used for immunization in mice. The ELISA results showed that all the domains elicited high antibody titres in vaccinated animals. However domain PAD3-4 showed the highest immune response against PA. Among the IgG subtypes, IgG1 response was predominant in all the immunized groups followed by IgG2. This indicated the induction of Th2 type immune responses against all the recombinant protein vaccine candidates.

炭疽芽孢杆菌是炭疽的病原体,被认为是最重要的生物战制剂。这种革兰氏阳性孢子形成细菌有三种感染方式,即皮肤、吸入和胃肠道感染。该细菌的主要毒力因子是由聚d -谷氨酸组成的抗吞噬胶囊和由保护性抗原(PA)、致死因子(LF)和水肿因子(EF)组成的分泌性三方细菌毒素。PA是炭疽毒素复合物的关键蛋白,对PA的免疫反应是预防炭疽杆菌的核心。在这项研究中,克隆和表达了四个不同结构域的重叠部分。重组蛋白经纯化后用于小鼠免疫。酶联免疫吸附试验结果显示,所有结构域在接种动物中均能引起高抗体滴度。而结构域PAD3-4对PA的免疫应答最高。在IgG亚型中,所有免疫组均以IgG1应答为主,其次为IgG2。这表明对所有重组蛋白候选疫苗都能诱导Th2型免疫应答。该研究表明,单个结构域也具有作为炭疽候选疫苗的潜力。

PA is the pivotal protein of the anthrax toxin complex and immune response to PA is central to protection against B. anthracis. In this study, overlapping portions of four different domains of PA were cloned and expressed. The recombinant proteins were purified and used for immunization in mice. The ELISA results showed that all the domains elicited high antibody titres in vaccinated animals. However domain PAD3-4 showed the highest immune response against PA. Among the IgG subtypes, IgG1 response was predominant in all the immunized groups followed by IgG2.

A biological attack employing the deliberate spread of Ebola virus by radicalized health care workers is a significant public health and national security threat. The chain of custody for medical materials contaminated with Ebola can be vast, and opportunities for health care workers to self-infect themselves with Ebola exist. As demonstrated in recent years, Westerners will support Islamic terror organizations by carrying out attacks on domestic soil. This paper addresses scenarios by which Ebola virus could be disseminated into unsuspecting populations by health care workers. Also elucidated are risk mitigation methods.
激进的卫生保健工作者蓄意传播埃博拉病毒的生物袭击是对公共卫生和国家安全的重大威胁。受埃博拉病毒污染的医疗材料的监管链可能非常庞大,医护人员也存在自我感染埃博拉病毒的机会。正如近年来所证明的那样,西方人会通过在国内发动袭击来支持伊斯兰恐怖组织。本文讨论了埃博拉病毒可能通过卫生保健工作者传播到毫无戒心的人群中的情况。还阐明了降低风险的方法。
