Asst. Lect. Wasan Redha Hassan from the Department of Biology published a scientific article on “Modern Techniques for Molecular Detection of Microbial Pathogens.”
Recent years have witnessed significant advancements in molecular diagnostic techniques, leading to a qualitative leap in the diagnosis of microbial pathogens. These techniques have surpassed traditional methods, which were limited in speed, sensitivity, and accuracy. Molecular techniques now provide more reliable diagnoses, directly impacting the management of infectious diseases and reducing their spread. These techniques now represent an essential part of public health systems and clinical laboratories worldwide.
One of the most important reasons for using molecular techniques in microbial diagnostics is their reliance on a set of characteristics that make them the ideal choice for diagnosing pathogens. These characteristics include: high sensitivity, allowing the detection of very small amounts of the pathogen’s genetic material; excellent specificity and the ability to distinguish between genetically related species; speed in obtaining results compared to traditional culture; the ability to detect pathogens that are not cultureable or grow slowly; and the ability to directly detect pathogens from clinical samples without the need for microbial isolation.
However, despite the significant development of these techniques, several challenges remain. These include high costs, especially for NGS techniques; the need for trained personnel in molecular diagnostic laboratories; managing the large datasets generated by gene sequencing; and ensuring the quality and efficiency of molecular analysis in clinical laboratories.
