A research team led by Professor Li Jiakui of Huazhong Agricultural University has developed an innovative and portable smart PCR detection device. This breakthrough technology allows for the rapid on-site diagnosis of major infectious diseases in yaks, marking a significant step toward "intelligent, precise, and on-site" disease control in China's high-altitude pastoral areas. The device provides crucial technological support for biosecurity and rural vitalization on the plateau.

The device boasts three key advantages. The first is rapid diagnosis. Using advanced quantitative fluorescent PCR technology, it delivers results in as little as 40 minutes, boosting efficiency by over 90 percent compared to traditional methods. The second is portability and intelligence. Weighing less than 5 kilograms, it is designed to be durable and resistant to low temperatures. The built-in AI system allows for automatic analysis, enabling frontline workers to operate it after minimal training. And the last key advantage is precision. With over 50 percent higher sensitivity and specificity than conventional test strips, the device can accurately identify pathogens and quantify viral loads. This provides a scientific basis for early warning, medication, and treatment evaluation, filling a critical gap in molecular diagnostics for plateau regions.

Yaks are a vital strategic livestock species on the plateau, and disease control is essential for herders' livelihoods and ecological safety. The new device can accurately detect over 10 major infectious diseases, offering a revolutionary tool for early diagnosis and disease tracing. It is expected to prevent over 100 million yuan ($13 million) in annual economic losses for herders. Additionally, the precise diagnosis helps guide scientific medication use, reducing antibiotic abuse and enhancing the quality of yak products.

This device is a significant technological leap and a testament to the dedication of scientists in serving national strategic goals and rural vitalization.
