Globally, infectious diseases are still the first cause of human death. These diseases are extremely harmful to human health, causing immeasurable economic losses and seriously affecting social and economic development, and have become a public health issue that WHO focuses on. Therefore, the subject of pathogenic biology is an important part of basic medicine, and it is necessary to solve the key problems of pathogenic biology research in medicine.

In 2005, the Department of Pathogenic Biology of Dalian University obtained master's degrees in two disciplines, which can be awarded with a master's degree in pathogenic biology (with a duration of 3 years). The discipline of pathogenic biology relies on the teaching and scientific research platforms such as Dalian University School of Medicine, Medical Research Center, Department of Medical Laboratory, Department of Pathogenic Biology, Liaoning Key Laboratory of Bioorganic and Liaoning Key Laboratory of Physiology as technical support, which provides a good scientific research platform for postgraduate training. This discipline has academic exchanges and cooperation with key universities and famous universities in China such as Harvard University, Osaka Medical University and Oxford University. Using the interdisciplinary advantages of Dalian University, three characteristic research directions have been formed: anti-infective immunity and its regulation mechanism, pathogen diagnosis and pathogenesis based on microfluidic chip, genetic engineering antibody and pathogen diagnosis.

There are full-time teachers 1 1 person in the subject of pathogenic biology, including 4 professors and 5 people with overseas experience, 9 of whom have medium-term doctoral degrees, accounting for 83% of full-time teachers, and 6 teachers under 45 years old, accounting for 54.5% of full-time teachers. In the past five years, the discipline has hosted 6 national natural science funds and 6 provincial and ministerial funds, with a total research funding of 3.6 million yuan and an annual per capita research funding of 60,000 yuan. Published 50 papers, including SCI and EI retrieval 12; Authorized 1 national invention patents.
