Microbix & Bulgaria’s NCIPD Execute Supply Agreement

MISSISSAUGA, Ontario and SOFIA, Bulgaria, July 08, 2025 (GLOBE NEWSWIRE) -- Microbix Biosystems Inc. (TSX: MBX, OTCQX: MBXBF, Microbix^®), a life sciences innovator, manufacturer, and exporter, and the National Center for Infectious and Parasitic Diseases of Bulgaria (“NCIPD”), announce an agreement whereby NCIPD will supply a portfolio of pathogen seedstocks for production of Microbix quality assessment products (“QAPs™”).

Following detailed discussions and a meeting at NCIPD in Sofia, Bulgaria, attended by Microbix’s CEO and NCIPD’s Director, the parties have executed a multi-year agreement under which NCIPD will supply organisms to Microbix on an exclusive basis in exchange for a license fee, material-transfer fees, and royalties on net sales of related QAPs. Through this collaboration with NCIPD, Microbix expects to commercialize multiple new QAPs (also known as test-controls) that will help ensure the accuracy and quality of multiple tests for diagnosing infectious diseases, thereby improving human health and well-being around the world. QAPs are inactivated and stabilized mimetics of patient samples, used to validate testing.

Founded in 1881, NCIPD was a pioneer of the modern fight against contagious and parasitic diseases and has since remained at the forefront of such national and international research. It is a national institution within the Ministry of Health, hosts all National Reference Laboratories, and provides postgraduate training in epidemiology, microbiology, virology, parasitology, and immunology. In 2007, the European Center for Disease Control (ECDC) in Stockholm designated NCIPD as a leading national “competent body” in the field of infectious and parasitic diseases. From its work, NCIPD has developed an extensive collection of bacteria, parasites, and viruses, which have clear provenance and have been extensively characterized.

In turn, Microbix has been a leading international producer of biological ingredients for nearly 40 years. It has leveraged its expertise to become a global leader in creating and manufacturing QAPs, which are used to regularly validate the whole workflow of diagnostic tests and thereby help ensure their ongoing accuracy. Microbix now offers approximately 300 QAPs for supporting infectious disease diagnostics tests and expects to meaningfully increase that number via its agreement with NCIPD.

Professor Dr. Iva Christova, Director of the NCIPD, commented, “International relationships are an integral part of our mandate at NCIPD, so we’re pleased to add Microbix as an active expert collaborator. It is critical that all tests to diagnose infections are optimally accurate, so NCIPD is delighted to have microorganisms from our library incorporated into QAPs that will support clinically-important tests.”

Pavel Zhelev, Director of Product Management at Microbix, also commented, “As a Bulgarian-Canadian, it was a delight to foster this agreement between Microbix and NCIPD. Bringing these two synergistic parties together enables the creation of new and innovative QAPs to help ensure the accuracy of emerging tests for bacterial, parasitic, and viral infections. We are grateful for the trust NCIPD is placing in Microbix through this collaboration.”
