However, few attentions have been paid to the seasonal distribution of airborne pathogens, in particular their associations with antibiotic resistance genes (ARGs). To this end, two-week daily PM\n                    <jats:sub>2.5<\/jats:sub>\n                    samples were consecutively collected from Nanchang in four seasons, and the human-to-human pathogens were screened based on high-throughput sequencing. The results showed that there were 20 pathogenic taxa in PM\n                    <jats:sub>2.5<\/jats:sub>\n                    in Nanchang, and the highest relative abundance of pathogens was observed in winter (5.84%), followed by summer (3.51%), autumn (2.66%), and spring (1.80%). Although more than half of pathogenic taxa were shared by the four seasons, the analysis of similarities showed that pathogenic community was shaped by season (\n                    <jats:italic>r<\/jats:italic>\n                    \u2009=\u20090.16,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&amp;lt;\u20090.01). Co-occurrence network analysis disclosed significant interactions among pathogens in each season. Moreover, some dominant pathogens such as\n                    <jats:italic>Plesiomonas shigelloides<\/jats:italic>\n                    ,\n                    <jats:italic>Bacteroides fragilis<\/jats:italic>\n                    , and\n                    <jats:italic>Escherichia-Shigella<\/jats:italic>\n                    were hub pathogens. In addition, PICRUSt2 predicted that there were 35 high-risk ARG subtypes in PM\n                    <jats:sub>2.5<\/jats:sub>\n                    , and the pathogens had strongly positive correlations with these ARGs. Even some pathogens like\n                    <jats:italic>Plesiomonas shigelloides<\/jats:italic>\n                    ,\n                    <jats:italic>Bacteroides fragilis<\/jats:italic>\n                    ,\n                    <jats:italic>Aeromonas<\/jats:italic>\n                    ,\n                    <jats:italic>Citrobacter<\/jats:italic>\n                    , may be multi-drug resistant pathogens, including beta-lactam, aminoglycosides, chloramphenicol and multi-drug resistances, etc. Both air pollutants and meteorological conditions contributed to the seasonal variation of airborne pathogenic bacteria (\n                    <jats:italic>r<\/jats:italic>\n                    \u2009=\u20090.15,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&amp;lt;\u20090.01), especially CO, O\n                    <jats:sub>3<\/jats:sub>\n                    , PM\n                    <jats:sub>2.5<\/jats:sub>\n                    , temperature and relative humidity.
