  • 摘要: 为探究施用有机肥对土壤中抗性基因和整合酶基因分布的影响及其与土壤环境因子的相关关系,利用高通量PCR技术监测了鸡粪有机肥施用120 d后土壤中四环素类抗性基因、大环内酯类抗性基因、整合酶基因和土壤理化性质的变化情况。研究结果表明,施肥土壤的电导率、pH、有机质含量均明显增加,而土壤氧化还原电位由217.27 mV降低到154.47 mV。施肥土壤中钾、氮、磷、铅、铜和锌含量均上升。施加鸡粪有机肥120 d后,土壤中tetM、tetQ、tetW、tetG和tetX 5种四环素类抗性基因相对丰度分别增加了2.90、0.97、6.80、0.98和0.94倍,而erm35、ermB、ermT、ermX和ermF 5种大环内酯类抗性基因相对丰度分别增加了0.98、136.68、0.95、2.89和2.89倍;但erm36相对丰度降低了0.75倍,其中施肥后土壤中ermB丰度最高而erm36丰度最低。施用鸡粪有机肥后,土壤中intI1和intI3的丰度分别降低了4.71 × 10-5和2.57 × 10-7,而intI2的丰度增加了3.74 × 10-6。Network分析发现intI3与除ermB外的基因均呈显著负相关关系(R=-1.00,P<0.05)。
