Steadfast – A complicated diagnostic package for detecting the extremely pathogenic H5N1 Avian Influenza Virus. Credit score: Diagnostics Growth Hub (DxD Hub)
The Diagnostics Growth Hub (DxD Hub), a nationwide platform hosted by the Company for Science, Expertise and Analysis (A*STAR), Singapore, in collaboration with the Nationwide Institute for Environmental Research (NIES), Japan, and the A*STAR Bioinformatics Institute (A*STAR BII), has efficiently developed Steadfast, a complicated diagnostic package for detecting the extremely pathogenic H5N1 Avian Influenza Virus (AIV).
This improvement marks a big breakthrough in avian influenza monitoring, reinforcing world efforts in pandemic preparedness.
Steadfast not solely gives fast detection of the extremely pathogenic H5N1 avian influenza virus (AIV) but in addition distinguishes between extremely pathogenic avian influenza (HPAI) and low pathogenic avian influenza (LPAI) strains, each of that are crucial for efficient management measures.
In contrast to typical sequencing strategies, which take two to 3 days for outcomes, this package can detect HPAI H5 strains (H5N1, H5N5, H5N6) in as little as three hours. This swift detection is essential for monitoring migratory birds, offering well timed warnings, and reinforcing biosecurity at poultry amenities.
HPAI strains, that are extremely deadly and unfold all through the physique of poultry, require fast culling of affected flocks to forestall extreme outbreaks. In distinction, LPAI strains are restricted to the respiratory and gastrointestinal tract and trigger delicate signs, permitting for much less drastic measures, resembling enhanced monitoring and biosecurity.
By enabling sooner identification of the particular pressure, the package permits for extra exact and well timed responses, considerably lowering transmission dangers and serving to to forestall probably devastating epidemics.
The extremely pathogenic H5N1 AIV is broadly unfold by birds, particularly poultry, by direct contact, contaminated surfaces, or contaminated droppings. Migratory wild birds typically carry the virus over lengthy distances, transmitting it to home poultry populations the place it may possibly set off extreme outbreaks.
As soon as contaminated, poultry act as reservoirs, probably spreading the virus to different birds and, in uncommon circumstances, to people who’ve shut contact. Regardless of restricted human transmission, H5N1 stays a crucial world concern attributable to its excessive mortality price and potential for mutation.
DxD Hub performed a key function within the improvement of the multiplex assay prototype take a look at kits, together with the design and improvement of avian scientific testing protocols, information evaluation, and assay optimization.
Validated by NIES, Japan’s main laboratory for avian influenza testing in wild birds, the package precisely categorised avian influenza viruses detected in wild birds in Japan between 2022 and 2024 as both excessive or low pathogenicity.
A*STAR BII supplied bioinformatics experience in virus sequence, construction, and evolution evaluation, supporting the combination of PCR diagnostics as a well timed, cost-effective complement to genomic surveillance. This enabled extra environment friendly detection and monitoring of ongoing H5N1 outbreaks.
This shut collaboration between DxD Hub, NIES and A*STAR BII was instrumental in refining the diagnostic package’s performance and making certain its effectiveness in detecting each HPAI and LPAI strains in real-world scientific and discipline purposes. This underscores the success of joint efforts to boost detection and management measures for avian influenza, serving to to curb the virus’s unfold and safeguard public well being.
“DxD Hub is pleased to have collaborated with global ecosystem partners like NIES and A*STAR BII to develop the H5N1 Avian Influenza Virus diagnostic test kit. This achievement reflects our shared commitment to enhancing zoonotic diseases surveillance and pandemic preparedness,” stated Dr. Weng Ruifen, Chief Government Officer of DxD Hub.
“Highly pathogenic avian influenza virus has caused mass mortality in chickens and wild birds not only in Japan but worldwide. Recently, infections have also been confirmed in seals, cats, cattle, and even from cattle to humans, drawing attention as a potential next pandemic virus,” stated Dr. Onuma Manabu, Head of the NIES Biodiversity Useful resource Conservation Workplace.
“Such occasions spotlight the virus’s fast mutation, emphasizing the significance of building an efficient surveillance system and creating sooner detection strategies that may promptly adapt to virus mutation to forestall the unfold of an infection.
“The kit developed in our joint project meets this demand, and its widespread use is expected to alleviate public anxiety and allow for a more flexible response to the spread of infection.”
“A*STAR BII is pleased to be part of this joint effort and to support the development of this advanced AIV diagnostic kit by lending our expertise in virus bioinformatics. Viral genomes evolve extremely quickly and often quietly, making speed and accuracy—through more discerning surveillance and rapid detection—critical for containing potential infectious disease outbreaks and minimizing zoonotic spillovers. With this kit, we can better safeguard food security, public health and economic stability in Singapore and around the world,” stated Dr. Sebastian Maurer-Stroh, Government Director of A*STAR BII.
