项目摘要

Project Summary Infectious diseases are caused by micro-organisms, such as bacteria, protozoa, viruses or fungi, which can be transferred through direct or indirect human contact. A viral infection occurs when a host's body is invaded by pathogenic viruses, such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19 and the current pandemic. This pandemic is the greatest public health challenge since the 1918 influenza pandemic and the biggest threat to destabilizing the global economy since World War II. As viruses tend to mutate quicker than other pathogenic agents (and thus newer strains emerge time and again), continuous research is required to combat infectious agents. For preclinical research, the most frequently used animal models are mice and rats. They offer an optimal combination of genetic proximity to humans, cost for breeding and colony maintenance possibilities due to their small size. Mice offer the broadest spectrum of available models. Rats are the second most frequently used mammal animal model. In fact, several SARS-CoV- 2 researchers are turning to rats. They are no more susceptible to COVID-19 than mice, but their larger size is an advantage, as, for example, researchers often want to do repetitive bleeding in an experiment but cannot do that with mice. Furthermore, as vaccine studies often assess how different doses affect antibody responses over several days, most toxicology studies of drugs also start in rat. To achieve intermittent infusions in most non-infectious disease research, the current prevailing administration modes for small animal research are manual (oral, intravenous, intraperitoneal, subcutaneous) requiring repeated handling by trained technicians. However, infectious disease researchers desire the least number of touchpoints possible with their infected animals, especially when sharp needles are involved The proposed FluidSync BSL3 system may aid the discovery of new treatments for COVID-19 by enabling candidate drugs to be administered to model animals infected with SARS-CoV-2 while minimizing investigator contact. It may also be used in the development of vaccines and antibodies. The system builds on the first and only wireless and tether-free administration system that can be used in animals as small as mice. The new system will have new capabilities including i) a medical-grade primary battery and ii) a programmable system-on-chip including Bluetooth telemetry transceiver, processor and memory. Ultimately, the FluidSync BSL3 microinfusion system would enable an intelligent instrumented vivarium system that addresses many BSL3 user requirements with benefits including increased productivity, reduced researcher exposure to potentially toxic drugs and disease vectors, ease of management of large-scale animal studies, and minimized animal handling to reduce white coat effects.

项目概要传染病是由细菌、原虫、病毒或真菌等微生物引起的，可以通过通过直接或间接的人际接触传播。当宿主的身体受到病毒入侵时，就会发生病毒感染致病病毒，例如严重急性呼吸综合征冠状病毒 2 (SARS-CoV-2)，该病毒导致了 COVID-19 和当前的大流行。此次疫情是自疫情爆发以来最大的公共卫生挑战 1918 年流感大流行是二战以来全球经济不稳定的最大威胁。由于病毒往往比其他病原体变异得更快（因此新的病毒株一次又一次地出现），需要持续研究来对抗传染源。对于临床前研究，最常用的是动物模型有小鼠和大鼠。它们提供了与人类的遗传接近度、成本的最佳组合由于其体型较小，因此具有繁殖和群体维持的可能性。小鼠提供最广泛的可用型号。大鼠是第二常用的哺乳动物模型。事实上，一些 SARS-CoV- 2 位研究人员正在转向老鼠。它们并不比老鼠更容易感染 COVID-19，但它们的体型较大这是一个优势，例如，研究人员经常想在实验中进行重复出血但无法做到与老鼠有关。此外，由于疫苗研究经常评估不同剂量如何影响抗体反应几天来，大多数药物的毒理学研究也在大鼠身上开始。为了在大多数非传染性疾病研究中实现间歇性输注，当前流行的给药方式小动物研究的模式是手动的（口服、静脉注射、腹膜内、皮下），需要由经过培训的技术人员重复处理。然而，传染病研究人员希望最少数量的可能与受感染的动物接触，尤其是涉及锋利的针头时拟议的 FluidSync BSL3 系统可以通过启用来帮助发现新的 COVID-19 治疗方法对感染 SARS-CoV-2 的模型动物施用候选药物，同时最大限度地减少调查员联系方式。它还可用于疫苗和抗体的开发。该系统建立在第一个也是唯一一个无线且无绳的管理系统，可用于小如小鼠的动物。新系统将具有新功能，包括 i) 医用级原电池和 ii) 可编程片上系统包括蓝牙遥测收发器、处理器和存储器。最终，FluidSync BSL3 微量输注系统将实现智能仪表化饲养系统满足许多 BSL3 用户需求，其优点包括提高生产力、减少研究人员接触潜在有毒药物和疾病媒介、易于管理大规模动物研究，以及尽量减少动物处理以减少白大衣效应。
