ANTIBIOTIC RESISTANCE: A GLOBAL THREAT TO HUMAN HEALTH

There is an alarming worldwide increase in antibiotic resistance. According to a new WHO report, between 2018 and 2023, antibiotic resistance rose in over 40% of the pathogen-antibiotic combinations, with an annual average increase of 5-15%. Dr Tedros Adhanom Ghebreyesus, WHO Director General, says antimicrobial resistance (AMR) outpaces modern medical advances. The Global antibiotic resistance surveillance report 2025 covers eight common bacterial pathogens that are rising in antibiotic resistance. These pathogens, which include Acinetobacter spp., Escherichia coli, Klebsiella pneumoniae, Neisseria gonorrhoeae, Salmonella spp., Shigella spp., Staphylococcus aureus and Streptococcus pneumoniae, are significant due to their widespread prevalence and the severity of the diseases they cause.
Remoteness from laboratory diagnostic services usually means AMR screening is unavailable, and doctors need to prescribe without antibiotic sensitivity data. These situations can lead to prescribing inappropriate antibiotics, which can worsen the patient's condition, develop more resistant strains of bacteria, and increase healthcare costs. This not only risks the life of the patient but also contributes to the overuse of last resort antibiotics. Not surprisingly, AMR is highly prevalent in war zones, where emergency life-saving treatments must occur in the absence of access to clinical diagnostic services.
Point-of-care diagnostic technology that can identify the pathogen and its antibiotic resistance status will become critical as a toolkit for addressing this worldwide problem.
DNAiTECH’s Gen3 portable LAMP-CRISPR technology is a versatile solution deployed anywhere to identify such pathogens rapidly. Being a battery-powered device, operational for multiple days without recharge, it ensures that power constraints do not hinder the diagnostic process, making it a reliable tool in various settings, such as primary care, veterinary care, LMIC situations, and conflict zones. DNAiTECH’s technology employs the powerful isothermal method LAMP, with CRISPR as the secondary proof-reading reaction, providing high sensitivity and specificity. The images provided illustrate the effectiveness of DNAiTECH’s technology in identifying Staphylococcus aureus by targeting the 16s and femA gene targets, as well as detecting mecA, the AMR marker. This approach differentiates MSSA (methicillin-sensitive) and MRSA (methicillin-resistant) strains. The graphical time course shows the CRISPR readout at 0, 5 and 10 minutes of colour development.

SENEGAL BOUND!

I'm heading to Senegal tomorrow with technology and diagnostic kits. In December 2024, the Gen3 technology platform development began, leading to the successful delivery of alpha versions of innovative point-of-care devices in record time. Packed and ready are five portable Gen3 instruments and two battery-powered sample preparation devices. Tomorrow, I'm heading to Dakar with 140 diagnostic chips for yellow fever and measles.

Gratitude is extended to those who made this milestone possible. Institut Pasteur Dakar (IPD), especially Cheikh Tidiane Diagne , Andy Diouf, Oumar Ndiaye, and Oumar Faye, for reaching out to DNAiTECH. Canadian Grand Challenges for funding IPD, enabling these proof-of-concept projects. Sprout Agritech's investment in DNAiTECH supported this technology development. Acknowledgment to Drazen Jaksic and David Swarbrick for their brilliant design work, to the DNAiTECH team in Blenheim – Calum, Honey, and Leeann – for their hard work in integrating innovative biochemistry into this technology. Thanks to the DNAiTECH Board – Kevin Darling, Rick Christie, and Marie Leroux – for their tremendous support. This diverse and talented group has brought this milestone to life. Remembering the Maori proverb: "He aha te mea nui o te ao? He tāngata, He tangata, He tangata!" What is the greatest thing? It is people, it is people, it is people.

DNAiTECH's vision is to bring innovative point-of-care molecular diagnostics to detect pathogens, anywhere, for agritech, veterinary and biomedical applications. In 2024, we were approached by the Institut Pasteur de Dakar (IPD) for the development of rapid point-of-care tests for measles and yellow fever. We have worked on this project for the last 12 months, and during these past two weeks, we have completed a significant key milestone. Andy Diouf, a scientist with IPD travelled from Dakar to Blenheim and joined the team to test our hardware and chip technology on real-world measles and yellow fever RNA samples. We had a fantastic time with Andy. While the sample numbers were small, we are pleased to report 100% sensitivity and 100% specificity. The next milestone will be a real-world trial in the field in Senegal, with larger numbers of clinical samples and all the temperature and humidity challenges that will come with it. But we aim to be ready for it!

MEASLES POINT-OF-CARE DIAGNOSTICS

DNAiTECH is contributing to a new project, “Development of a Molecular Rapid Detection Test for Measles Virus Diagnosis” supported by Grand Challenges Canada funding to Fondation Institut Pasteur de Dakar.
Measles is a serious and highly contagious disease. It can cause serious problems, including brain swelling, chest infections, or death. Since covid, there has been a resurgence of measles cases worldwide, caused by a reduction in vaccination during the pandemic and a rise in vaccine hesitancy.
At DNAiTECH we have developed PLACID, “paper-based LAMP CRISPR integrated diagnostics. This is a diagnostic chip technology, enabling the definitive molecular detection of pathogens. We anticipate trials with PLACID diagnostic chips for measles and rubella to be tested with scientists from the Fondation Institut Pasteur de Dakar in Senegal in early 2025.

S-TECH: DNAiTECH'S SAMPLE PROCESSING TECHNOLOGY

In 2023 we launched S-TECH, our sample processing technology for our point-of-care diagnostics tests. S-TECH enables sample processing beyond the lab, without requiring the equipment of a modern laboratory. With S-TECH, nucleic acid samples can be prepared from any sample type. To date, the samples tested include tissue biopsies, nasal and throat swabs, blood samples, f***l samples, urine samples, plant tissue, soil samples, bacterial cultures, bee-hive samples and environmental water samples. For all of these sample types, the S-TECH nucleic acid extraction system uses two filters (A+B), the B filter incorporates the classical glass-fibre capture of DNA, yielding DNA that is inhibitor free and readily amplifiable by isothermal methods.

As well as nucleic acid extractions, another form of S-TECH can be used for the isolation of subcellular particles such as EV and microvesicles. The use of EV's in diagnostics is a rapidly growing area, isolation of EVs non-invasively has great potential for disease detection. By incorporating track-etched membranes into S-TECH, subcellular particles can be readily isolated using our S-TECH-EV filter. A video demonstrating the simplicity of using our single S-TECH-EV filter to isolate subcellular particles from urine is shown below.
