Happy Friday! Since Tuesday was Valentine’s day, it was fitting to have a super romantic story about Ebola super-spreaders and their role in causing most of the cases. Have you ever wondered why killer viruses are on the rise or what some of these infectious disease terms mean?
ASM Biothreats 2017 Highlights
If you missed this event or weren’t able to make some of the sessions, check out our overview! GMU sent four graduate biodefense students to ASM’s biothreats conference to not only aid in their education, but also to report back for our readers. With their unique backgrounds, we’ve got articles on the FDA’s Animal Rule, international biosecurity efforts, and more. Check out the link above and you’ll find a special edition post with all of our highlights.
A Step Closer Towards Human Embryo Editing
A new report from an international committee put together by the U.S. National Academy of Science and the National Academy of Medicine found that a clinical trial regarding DNA editing of a human embryo “might be permitted, but only following much more research” on risks and benefits, and “only for compelling reasons and under strict oversight.” Consideration would be given to couples who are both afflicted with serious genetic disease and editing is “really the last reasonable option” for them to have a healthy child. While some applaud this as a first step towards a very specific and narrow subset of DNA altering, “others see the report as lowering the bar for such experiments because it does not explicitly say they should be prohibited for now. ‘It changes the tone to an affirmative position in the absence of the broad public debate this report calls for,’ says Edward Lanphier, chairman of the DNA editing company Sangamo Therapeutics in Richmond, California.” You can read the full report here.
The Biotechnological Wild West: the Good, the Bad, and the Underknown of Synthetic Biology
GMU Biodefense PhD student and Predoc at Lawrence Livermore National Laboratory, Yong-Bee Lim, is taking on the 2017 ASM Biothreats conference and the pipette-slinging world of synthetic biology. Lim first focuses on the panel at ASM’s conference, which looked at the current state of synbio and where the future might take us. Like most things in life, there’s also a flip side to that coin – the negative aspects of this new technology. “While the benefits derived from synthetic biology are great, presenters noted that it suffers from the dual-use dilemma: the same information applied to beneficial uses could also be repurposed for nefarious purposes. Dr. Hassell noted that synthetic biology increases biologically-derived risks through three mechanisms. First, synthetic biology can be used to enhance existing microbial threats; synthetic biology allows actors to more easily manipulate the characteristics of microbes, including increasing environmental stability and introducing hypervirulence. Secondly, traditional methods of restricting access to biological select agents and toxins (BSATs) may be less effective in an age where synthetic biology can be used to construct microbes de novo. Finally, synthetic biology can be used to construct novel threats that are meant to subvert countermeasures.” Lastly, one of the most interesting components to this presentation and Lim’s article is the underknown components to synethic biology. The erosion of the knowledge and technical barriers and the rise of the do-it-yourself (DIY) practitioners all give way to a new frontier in terms of benefits and dangers.
Broad Institute Wins CRISPR Patent
This week, the U.S. Patent Office appeal board ruled that the dispute regarding the discoveries between the University of California, Berkeley and the Broad Institute do not overlap. “The ruling is a win for the Broad Institute, which had asked for the finding of no interference. It will be able to retain its valuable patents, which cover the use of CRISPR in human and animal cells. In a statement, Berkeley said it “respects” the decision but still maintains that Berkeley biochemist Jennifer Doudna and European collaborator Emmanuel Charpentier were the first to invent the CRISPR system.” The CRISPR patent dispute has brought to light the most foundational question of who truly owns the patent rights to CRISPR work in animals and plants. This new development doesn’t mark the end of the CRISPR dispute, as many expect Berkeley to appeal the decision and the Broad Institute’s patent is facing dispute from other researchers, including the Rockefeller University. While the CRISPR patent road may have been smoothed for a bit, it will continue to remain rocky and cause ripples for business developments and the biotech industry.
Defense Civil Support: DoD, HHS, and DHS Should Use Existing Coordination Mechanisms to Improve Their Pandemic Preparedness
In this Government Accountability Office (GAO) report, they found that the DoD should utilize guidance developed to aid in support of civil authorities (specifically HHS and DHS). “HHS and DHS have plans to guide their response to a pandemic, but their plans do not explain how they would respond in a resource-constrained environment in which capabilities like those provided by DOD are limited. DOD coordinates with the agencies, but existing coordination mechanisms among HHS, DHS, and DOD could be used to improve preparedness. HHS’s Pandemic Influenza Plan is the departmental blueprint for its preparedness and response to an influenza pandemic.” The GAO’s goal was to assess the DoD’s plans and processes to support civil authorities during a pandemic, of which they found that the existing coordination mechanisms should be used to explore opportunities to improve preparedness if their capabilities are limited.
Global Health Security Transparency
Global health security is a finicky creature as it requires cooperation and transparency from all countries. One weak link in the chain can cause an international public health crisis. No More Epidemics is imploring countries to publish their Joint External Evaluations (JEE) performed by the GHSA (Global Health Security Agenda). As of now, only Ethiopia, Liberia, Peru, Uganda, UK, and the U.S. have openly shared their JEE’s. “Knowledge of baseline data provided by the JEE will result in more effective programming, prevention and detection of infectious disease outbreaks and early response. The JEE and roadmap processes are critical tools for civil society to use in developing appropriate and adequate programming to help countries close health systems gaps and become IHR-compliant. Transparency and accountability are vital in addressing global health threats. No More Epidemics urges all countries carrying out their Joint External Evaluations to make the results publicly available and for these to be made available on the World Health Organization’s Strategic Partnership Portal, the online repository for tracking funding, donor profiles and country level data.” Information sharing is also a mechanism for strengthening partnerships among countries.
Webinar on Ebola’s Aftermath
Doctors Without Borders (MSF) will be hosting this live webinar on Thursday, February 23rd at 8pm EST. Following the publication of the book, The Politics of Fear: Médecins Sans Frontières and the West African Ebola Epidemic, the MSF webinar will do a deep-dive into the 2014/2015 outbreak and the lessons learned. This event will include a panel of MSF experts, who were directly involved in the MSF response in West Africa.
Fighting Antimicrobial Resistance with Physics
The battle against antimicrobial resistance (AMR) isn’t slowing and the proposed strategies emphasize the need for increased research and development of new antimicrobial agents, which means we’re running out of options. Swinburne University is trying a new tactic though – physics. “Elena Ivanova was studying physical surfaces that could repel bacteria before they even had time to settle. In clinical settings, such as hospitals and dental practices, 80% of infections are caused by bacteria that cling to surfaces in such densities that no antibiotic can remove them. First, she tried making surfaces so smooth that bacteria would, theoretically, simply slide off. Although that was the case for some bacteria, many others—such as the common Staphococcus aureus, or staph—still managed to cling on and multiply.” This is where Greg and Jolanta Watson come in – they have amassed a huge collection of biological samples in their laboratory. Ivanova and the Watsons communicated back and forth regarding natural properties that might make bacteria incapable of sticking to and growing on surfaces. Starting with cicada wings, Ivanova found that it was able to kill one of the two main types of bacteria, which was a partial success. Next, a gecko’s skin was tested, which revealed a wealth of knowledge. “Green had added a sample of the small, rod-shaped bacterium that causes gingivitis, Porphyromonas gingivalis, to the surface. In total, he added around 10 million microbes every day for a week. What’s more, this mass of microbes was given everything that they needed for a good life: a constant temperature of 98.6˚ F, an atmosphere without oxygen, and a daily ration of food. Regardless, after the week, nearly all were punctured and torn, their cellular carcasses strewn over the gecko skin. ‘Bacteria are trying to move and settle on the surface,’ Green says. ‘And they’re just getting spiked and skewered by these long hairs’.” Looking to nature, these researchers have focused on the physics of repelling bacterial growth, which may help broaden the arsenal against resistant germs.

- Surprise Us, Mr. Trump – A Letter From the Global Health Community – In this editorial article from The Lancet Global Health, the authors point to the role of the U.S. in the WHO Executive Board and the future of WHO leadership. “Two legislative bills introduced in early January in the US House of Representatives and Senate are seeking to withhold funds from the UN and open a way for the USA to leave the global body, and therefore withdraw membership of WHO.” The current political and global health atmosphere is unsettled, which has many concerned about the future of U.S. involvement in global health programs.
- CRISPR Creates TB-Resistant Cattle – Chinese researchers have created tuberculosis resistance in cattle using CRISPR/Cas9. “As the researchers reported today in Genome Biology, they used somatic nuclear transfer to get the edit into an egg cell, creating 11 cows in vitro with NRAMP1 (nine using Cas9 nickase) and demonstrating that the gene provided increased resistance to tuberculosis.Moreover, they said that while the Cas9 nickase did not completely eliminate off-target edits, it did reduce them, especially when compared to standard Cas9 which creates double-strand breaks and is much more likely to create indel mutations via the non-homologous end-joining DNA repair pathway.”
