Abstract:

The aim of this study was to investigate the bacterial community structure and the characteristics of pathogenic bacteria in the air of sheepfold. We selected ten different sheep farms to take air samples. The Illumina MiSeq sequencing with 16S rRNA V3-V4 variable region was adopted to analyze the bacterial community structures of the air in sheepfold. A total number of 33 408 operational taxonomic units (OTUs) were obtained from air samples under the similarity level of 97%. We have got bacteria comprising groups of 25 phyla, 66 classes, 123 orders, 253 families, 547 genera, and 444 species. Analysis of microbial diversity and summarize pathogens with higher abundance in sheepfolds, which provides the basis for the disinfection and medication for sheep farm. The diversity, abundance, and characteristics of the main pathogens in air samples were analyzed in this study, which would be a helpful reference for disease prevention and control in sheepfold.
