MGI Contributes to Rapid Detection and Surveillance of COVID-19 Omicron Variant
SHENZHEN, China, Dec. 15, 2021 /PRNewswire/ -- MGI Tech Co., Ltd. ("MGI"), a global life science leader and innovator, is playing an instrumental role in the global battle against the omicron variant of COVID-19 with its DNBSEQ™ and ATOPlex technologies. As a responsible global company, and as omicron begins to rapidly spread around the world, MGI's innovative equipment has been used in the detection, monitoring, surveillance, and tracing of the new variant to safeguard the global community in more than 70 countries worldwide to date.
Supporting detection of omicron in South Africa's wastewater with rapid sequencing and ATOPlex technology
In light of the increasing dominance of the omicron variant in South Africa, researchers across the country are turning to MGI to ramp up their screening efforts and manage the spread of COVID-19 through sequencing of wastewater samples. Wastewater surveillance is key to pandemic management as it can rapidly identify COVID-19 hotspots and circulating variants, which can in turn inform a rapid public health response.
The South African Medical Research Council (SAMRC) was the first report of the Omicron variant being detected in the City of Cape Town's wastewater system and the detection coincides with an increase in cases in the city. "At the South African Medical Research Council, our team used the MGI ATOPlex technology and the DNBDEQ-G50* to sequence SARS-COV-2 from wastewater samples collected from wastewater treatment plants across South Africa. This technology was instrumental in confirming the presence of omicron at in a sample collected at Cape Town International Airport before omicron was first announced". Said Prof Craig Kinnear, Human Geneticist and Platform Manager of the SAMRC Genomics Centre.
MGI ATOPlex technology is a two-step multiplex PCR method which amplifies all viral fragments in one tube providing target enrichment, amplification, and library construction in one simple process. It is relatively cheap, available, and fast in comparison to other PCR methods. It is an ultra-short amplicon-based method (106-199bp) which can capture more shorter fragments direct from a clinical sample or environmental sample and is more likely to obtain a complete viral genome sequence. Moreover, ATOPlex introduces a DNA spike-in control in the two-step multiplex PCR process. The DNA spike-in control was co-amplified with SARS-CoV-2 coupled to count-based analysis to accurately detect SARS-CoV-2, quantify its viral load, and measure the cross-contamination1.
ATOPlex is designed to work in tandem with MGI's DNBSEQ™ genetic sequencing technologies, such as the DNBSEQ-G50*, DNBSEQ-G400*, and DNBSEQ-T7*.
Enabling the discovery of the first case of the omicron variant in Sweden and Saudi Arabia
In addition to the detection and surveillance of omicron in South Africa, MGI has supported other nations to detect the first cases of the variant in their country. Its ATOPlex technology was integral in supporting the National Pandemic Center (NPC) at Karolinska Institutet in Sweden to discover its first case of the COVID-19 omicron variant. In Saudi Arabia, MGI supplied its ATOPlex technology and DNBSEQ-G400* rapid sequencing platform to support the Kingdom's Ministry of Health, which was responsible for detecting the first case of the omicron variant from a citizen coming from North Africa.
