AsianScientist (Jan. 12, 2023) – The world stood nonetheless in March 2020 when the World Well being Group declared a pandemic. Attributed to extreme acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the COVID-19 outbreak had compelled nations into lockdowns, disrupted livelihoods and overloaded healthcare techniques worldwide. Three years on and the results of the pandemic nonetheless linger.
But, COVID-19 will not be the world’s first infectious illness outbreak—and neither will or not it’s the final. A 2021 research expects the annual probability of an epidemic to extend threefold within the a long time to return, and that it will take lower than 60 years for one more pandemic to strike. With outbreaks periodically occurring, just like the Ebola epidemic in Africa, viral analysis and surveillance have turn into crucial.
“Many areas are hotbeds for novel and current viruses, which may emerge anytime. We have to be extra proactive in monitoring and managing them in addition to reducing them off earlier than they unfold like wildfire,” mentioned Dr Emily Leproust, Chief Govt Officer of Twist Bioscience.
Twist Bioscience is a world biotechnology firm with an expansive options portfolio catering to numerous fields, together with diagnostics and therapeutics. From next-generation sequencing (NGS) to deoxyribonucleic acid (DNA) synthesis, it gives revolutionary instruments for most cancers analysis, drug discovery and infectious illness surveillance. Its options middle on course enrichment, a scalable and cost-effective strategy that the corporate has perfected to allow areas of a genome to be remoted for extra exact and in-depth sequencing.
“Polymerase chain response (PCR) is a conventional approach to detect viruses in a pattern. Nonetheless, it’s liable to false negatives as it’s unable to find out the character of the virus or whether or not the virus has developed over time,” defined Dr Leproust. “Goal enrichment overcomes these shortcomings and is unbiased and agnostic sufficient to both pull down particular areas for sequencing or be used for broader assays.”
Considered one of Twist Bioscience’s goal enrichment options is the Complete Viral Analysis Panel for NGS to detect viruses—each recognized and novel—and to trace their mutation and transmission. The extremely sturdy panel can sequence and establish greater than 3,000 human and non-human viruses and over 15,000 viral strains in a single pattern. The panel also can establish particular person viral genomes, from coronaviruses to papillomaviruses to influenza A and B, in numerous advanced mixtures like wastewater and meals.
In keeping with Dr Leproust, the Complete Viral Analysis Panel is right for viral surveillance in communities due to the breadth and variety of its protection and its functionality of detecting novel viruses and variants. It may assist authorities our bodies and researchers to periodically acquire and take a look at wastewater samples for the presence of pathogens to observe viruses, perceive advanced ailments and stop potential outbreaks.
In truth, an earlier iteration of the Complete Viral Analysis Panel was used to find out the origin of the monkeypox virus through the 2017–2018 outbreak in Nigeria. “This panel is definitely the second iteration of our Pan Viral Panel. With the assistance of the US Military Medical Analysis Institute of Infectious Ailments (USAMRIID) and Illumina, we designed this preliminary panel and probes in 2017, which had been instrumental to discovering the primary monkeypox virus liable for the outbreak,” added Dr Leproust.
For a extra centered panel, Twist Bioscience gives the Respiratory Virus Analysis Panel, which detects widespread respiratory viruses, together with SARS-CoV-2, human rhinovirus and adenovirus. The panel can be able to detecting low viral hundreds and distinguishing between signs to pinpoint the precise viral trigger and establish co-infections.
“We developed the Respiratory Virus Analysis Panel following the success of our SARS-CoV-2 panel. There have been many clinicians who needed a software that may decide the presence of respiratory co-infections together with SARS of their sufferers. So, we expanded the panel’s scope and sensitivity to enhance our understanding of the etiology of respiratory ailments,” shared Dr Leproust.
Each the Complete Viral Analysis Panel and Respiratory Virus Analysis Panel comply with a easy sequencing workflow, making them simple to undertake in any molecular biology or diagnostics laboratory. The panels additionally include entry to One Codex, a cloud-based platform that analyzes the pattern and permits simple interpretation of the outcomes by studies and visible information.
At its core, Twist Bioscience is a number one innovator of DNA synthesis. Aside from its panels, it’s well-known for artificial controls that assist guarantee the standard, accuracy and sensitivity of NGS and reverse transcription PCR assays. These artificial controls are safer and extra accessible alternate options to reside viruses, and may help viral surveillance and illness detection. Twist Bioscience gives artificial controls for respiratory, SARS-Cov-2 (together with variants of curiosity and of concern) and monkeypox viruses.
“We have now leveraged our power in making correct artificial fragments at a scale that may be catered to any analysis assays, whether or not they’re based mostly on DNA or nucleic acid. Our totally artificial controls have been cut up into 5 or 6 particular person fragments however they signify the entire viral genome,” mentioned Dr Leproust.
Actual-world applicability is the target of any resolution, and Twist Bioscience’s options have been validated by a number of clinicians and researchers who additionally present suggestions that the corporate makes use of to refine its merchandise. However what units Twist Bioscience aside available in the market is how simply scalable its options are.
“Considered one of our distinctive benefits is that we will scale our goal enrichment options in response to a buyer’s analysis wants anytime, comparable to including extra virus species and strains to our panels. Our design and probe-making processes are so fine-tuned that we will accommodate a shopper’s request inside 4 weeks,” emphasised Dr Leproust.
Because the world prepares itself for future viral outbreaks whereas nonetheless reeling from the COVID-19 pandemic, Dr Leproust envisions sturdy and scalable options for viral surveillance as the way in which ahead: “Greater than 50 % of the world’s inhabitants is in Asia, and any outbreak right here could cause havoc. With options just like the Complete Viral Analysis Panel, we will monitor hotspots to detect new viruses early and hold our communities secure.”
