Abstract: Objective The study aims to understand Leptospira infection in rodents at key ports along the Belt and Road.Methods Rodents were caught at 10 border ports using night trap methods and tissues or blood samples were collected to detect the infection of Leptospira by gradient PCR and subsequent sequencing.Results A total of 356 rodents were captured from 10 ports.Morphological identification revealed 2 orders,5 families,15 genera,and 20 species.The positive rate for Leptospira infection was 1.97%by nucleic acid testing.Among them,4 cases were Leptospira borgpetersenii in the northern ports,and the rest 3 cases were L.interrogans in the southern ones.Conclusions With the different composition of rodents at different key ports along the Belt and Road,the bacteria in rodents,especially for Leptospira,differ between different port areas,suggesting the urgent need for monitoring,prevention,and control.
