MBX Microbix Biosystems Inc

Microbix Biosystems Inc. (TSX: MBX, OTCQX: MBXBF, Microbix®), a life sciences innovator, manufacturer, and exporter, announces that it is presenting results of a novel Quality Assessment Product (“QAP™”) for supporting patient diagnosis and tissue analysis relating to infection with the Herpes Simplex Virus (“HSV”) at the European Meeting on Molecular Diagnostics (“EMMD”) taking place in Noordwijk, The Netherlands, October 9 to 11, 2024.

At EMMD, Microbix will interact with key opinion leaders, collaborators, and customers that create and utilize the available assays to diagnose, screen, and direct treatment of HSV, many other infectious diseases, and other conditions such as cancers. Microbix will also be attending multiple scientific and clinical care lectures and discussions that are directly pertinent to its ever-growing portfolio of QAPs that help ensure the accuracy of molecular (i.e., “PCR”) tests and their workflows.

Also at EMMD, Microbix will present its poster titled “FFPE HSV-1 and HSV-2 simulated tissue sections mounted on slides for use as prospective quality controls in IHC and qPCR workflows.” The poster reviews the performance of a novel (RUO) QAP to support PCR-based detection of HSV and immunohistochemical analysis of Formalin-Fixed and Paraffin-Embedded (“FFPE”) tissue samples. Following presentation of the poster on the afternoon of October 9th, it will be made available at https://microbix.com.

In spite of efforts to detect, treat, and prevent the spread of HSV, it is estimated that over half of all people worldwide are chronically infected with a strain of this virus. Emerging research is also establishing that chronic infection with HSV is a risk factor for, and can lead to, severe conditions like esophagitis, hepatitis, pneumonia, encephalitis, cancer, and neurodegenerative disorders. More widespread diagnosis of HSV and detailed analysis of infected tissues may therefore be a route to prevention of the serious health consequences that can result from HSV infections. Microbix is pleased to support the more widespread use of such testing by helping to ensure its quality and accuracy.

Pavel Zhelev, Microbix’s Director of Product Management and a co-author of the poster commented, “We believe our latest QAP is the first test-control that is fully consistent and reproducible for supporting both molecular and immunohistochemical analyses of HSV-infected FFPE tissue samples. We are pleased to support cutting-edge science in this field of chronic infection and resulting genetic damage – building from our portfolio of industry-leading test-controls in liquid, Copan FLOQSwab, and FFPE formats.”

Microbix gratefully acknowledges two external collaborators on this work, namely Sunnybrook Research Institute (Canada), and QuidelOrtho Corporation (United States).
