In a groundbreaking development, UK-based iFAST Diagnostics is set to transform the landscape of antimicrobial susceptibility testing with its innovative impedance-based technology. This new approach promises to deliver test results in just three hours, a significant improvement over the traditional 48-72 hour timeframe. This advancement could play a crucial role in combating antimicrobial resistance, a growing global health threat.
The iFAST system leverages microchip technology to perform electrical analysis of bacterial samples. This method involves measuring changes in electrical impedance as bacteria interact with various antibiotics. The process begins with Gram staining and sample enrichment, followed by mixing bacteria into growth media within a 96-well plate containing freeze-dried antibiotics. After a two-hour incubation, the system uses multi-frequency impedance to detect changes in bacterial growth, providing data on drug resistance and minimum inhibitory concentrations for up to 15 antibiotics per sample.
This impedance-based approach offers several scientific advantages:
Speed: Traditional culture-based AST methods require 48-72 hours to yield results. In contrast, iFAST’s technology reduces this to under three hours, enabling faster clinical decision-making.
Accuracy: By analysing the electrical properties of bacteria, the system can detect subtle biophysical changes, allowing for precise identification of effective antibiotics1.
High Throughput: The microchip can analyse thousands of bacteria simultaneously, making it suitable for high-volume clinical settings.
The introduction of iFAST’s technology comes at a critical time. Antimicrobial resistance is a pressing issue, with predictions indicating a significant rise in drug-resistant infections by 2050 if effective interventions are not implemented1. The ability to quickly and accurately determine the most effective antibiotic treatment can save lives, particularly in severe cases such as sepsis.
iFAST’s system not only shortens the time to obtain AST results but also integrates seamlessly with existing pathogen identification methods like MALDI-TOF mass spectrometry. This compatibility ensures that the technology can be adopted without overhauling current laboratory workflows.
From an industry perspective, iFAST’s innovation positions it as a key player in the rapidly evolving market for rapid phenotypic AST systems. Competing technologies, such as BioMérieux’s Vitek Reveal and Selux Diagnostics’ Next Generation Phenotyping System, also aim to reduce turnaround times but vary in their approaches and specific applications.
iFAST Diagnostics’ impedance-based AST technology represents a significant leap forward in the fight against antimicrobial resistance. By providing rapid, accurate results, this system has the potential to improve patient outcomes and reduce the spread of drug-resistant infections. As iFAST prepares to launch its technology in the UK and expand globally, it stands poised to make a substantial impact on global healthcare.
In a significant move to bolster public health preparedness, the Centers for Disease Control and Prevention (CDC) has partnered with Alveo Technologies to develop a point-of-need molecular diagnostic (MDx) test for Avian Flu A(H5). This collaboration aims to enhance early detection and response capabilities for avian influenza, a virus with the potential to cause severe outbreaks in humans.
Alveo Technologies will utilize its proprietary IntelliSense molecular detection technology to create a rapid, multiplexed diagnostic test. This technology employs isothermal nucleic acid amplification, which allows for the detection and differentiation of multiple influenza strains, including Influenza A, B, and the H5 subtype, from a single sample.
Key scientific features of this technology include:
Speed and Efficiency: The IntelliSense platform can deliver results quickly, providing critical information at the point of need. This rapid turnaround is essential for timely intervention and treatment.
Multiplexing Capability: The ability to simultaneously test for multiple strains of influenza enhances the test’s utility, particularly in distinguishing between seasonal flu and avian flu strains.
Portability: The platform is designed to be portable and easy to use, making it suitable for deployment in various settings, from clinics to field operations.
The development of this point-of-need diagnostic test is a proactive step in addressing the threat posed by avian influenza. The H5 subtype has been detected in birds, poultry, and even humans in the United States, raising concerns about potential human-to-human transmission. By decentralizing testing capabilities, Alveo’s technology can reduce the burden on centralized laboratories and ensure that critical diagnostics are accessible where they are most needed.
From a public health perspective, this partnership is a strategic move to enhance surveillance and response efforts. The ability to quickly identify and differentiate influenza strains can significantly improve outbreak management and containment strategies. Moreover, the integration of real-time data reporting via a secure cloud-based portal ensures that health authorities can monitor and respond to emerging threats more effectively.
Alveo Technologies’ approach aligns with broader efforts to improve global health security. By providing rapid, accurate diagnostics at the point of need, the company is contributing to a more resilient healthcare system capable of responding to infectious disease threats.
The CDC’s collaboration with Alveo Technologies marks a pivotal advancement in the fight against avian influenza. The development of a rapid, point-of-need diagnostic test for the H5 subtype will enhance early detection and intervention, ultimately improving public health outcomes. As Alveo continues to innovate in the field of molecular diagnostics, its contributions will be vital in managing and mitigating the impact of infectious diseases.
