Abstract:
Objective To monitor rodent species in the southern Fujian ports of China and investigate the natural pathogens they carry. Methods Rodents were captured using night-trapping and cage method across 17 port areas in southern Fujian in 2023. Morphological identification was performed to classify the captured specimens. Tissues from the liver, spleen, lungs, kidneys, and bladder were harvested for nucleic acid extraction. Nested and conventional PCR method were used to detect seven pathogens: Yersinia pestis, Hantavirus, pathogenic Leptospira, Borrelia burgdorferi, Bartonella, Orientia tsutsugamushi, and Anaplasma phagocytophilum. The Chi-square test was used to analyze the distribution of rodents and the status of natural pathogen infections across the study sites. Results A total of 161 rodents across five species belonging to two orders, two families, and three genera were captured. Suncus murinus was the dominant species(72.67 %), followed by Rattus tanezumi(13.04 %). Six pathogens were detected, with an overall positivity rate of 18.01%. Bartonella had the highest positivity rate(11.18%), followed by pathogenic Leptospira(4.97%), Borrelia burgdorferi(2.48%), Orientia tsutsugamushi(1.86%), Seoul virus(1.24%), and Anaplasma phagocytophilum(0.62%). Co-infections were noted in five rodents, representing 17.24% of those that tested positive, and one rodent was infected with four pathogens. No Y. pestis or Hantaan virus was detected in the captured rodents. Conclusions The rodents in the southern Fujian ports are naturally infected with multiple pathogens, including Bartonella, pathogenic Leptospira, and Seoul virus. Enhanced monitoring of rodent populations and the implementation of preventive and control measures for rodent-borne diseases are essential.
