Microbial Risks Caused by Livestock Excrement: Current Research Status and Prospects

Abstract

Livestock excrement is a major pollutant yielded from husbandry and it has been constantly imported into various related environments. Livestock excrement comprises a variety of microorganisms including certain units with health risks and these microorganisms are transferred synchronically during the management and utilization processes of livestock excrement. The livestock excrement microbiome is extensively affecting the microbiome of humans and the relevant environments and it could be altered by related environmental factors as well. The zoonotic microorganisms, extremely zoonotic pathogens, and antibiotic-resistant microorganisms are posing threats to human health and environmental safety. In this review, we highlight the main feature of the microbiome of livestock excrement and elucidate the composition and structure of the repertoire of microbes, how these microbes transfer from different spots, and they then affect the microbiomes of related habitants as a whole. Overall, the environmental problems caused by the microbiome of livestock excrement and the potential risks it may cause are summarized from the microbial perspective and the strategies for prediction, prevention, and management are discussed so as to provide a reference for further studies regarding potential microbial risks of livestock excrement microbes.

Effects of antibiotic resistance genes on health risks of rivers in habitat of wild animals under human disturbance – based on analysis of antibiotic resistance genes and virulence factors in microbes of river sediments

“…Microbial risk is indeed a significant aspect of “One Health” (Wu et al., 2023), and it is also an important component for assessing environmental health risks (Abdugheni et al., 2023). Antibiotic resistance genes (ARGs) in microbes represent a critical concern when evaluating microbial risks (Li et al., 2022; Shao et al., 2018).…”
