Infections and Influencing Factors of Pathogens inalong the Zengjiang River in Guangzhou, China.

Abstract

can carry and transmit various zoonotic pathogens. Some studies were conducted to investigate a few zoonotic pathogens in Guangzhou, China, but no coinfections were investigated or specifically mentioned. Studies on the infections and the influencing factors of various zoonotic pathogens inalong the Zengjiang River in Guangzhou have not been carried out.In this study,was captured in November 2020 and September 2021 along the Zengjiang River, and was tested forspp.,spp.,,, Hantavirus (HV),spp., and severe fever with thrombocytopenia syndrome virus (SFTSV) by the RT-PCR. Logistic regression analysis was used to determine the impact of habitat and demographic factors on the infections and coinfections of the surveyed pathogens.In 119, the detection rates ofspp.,spp.,,, and HV were 46.2%, 31.9%, 5%, 0.8%, and 18.5%, respectively.spp. and SFTSV were negative. The triple coinfection rate ofspp.,spp., and HV was 11.8%. In addition, the coinfection ofspp.,spp., andwas 0.8%. Dual coinfection ofspp. andspp.,spp. and HV,spp. and,spp. and, and HV andwas 9.2%, 3.4%, 1.7%, 1.7%, and 0.8%, respectively. Infections of these pathogens inwere found in habitats of banana plantation, grassland, and bush. Weight affected the infection ofspp.,spp., or HV inalong the Zengjiang River not only carried various potentially zoonotic pathogens but also had a variety of coinfections. Surveillance of the density and pathogens inshould be strengthened to reduce the incidence of relevant zoonotic diseases.
