鸡源结肠弯曲菌耐药性分析

为了解江苏省鸡源结肠弯曲菌的流行情况和药物敏感性,对江苏省不同规模化养鸡场、农贸市场和超市的鸡泄殖腔样品和鸡肉产品进行结肠弯曲菌的分离及PCR鉴定;采用纸片扩散法测定分离株对17种抗菌药物的敏感性。结果显示,从750份样品(禽肉产品和泄殖腔棉拭子)中分离到81株结肠弯曲菌,分离率为10.8%。耐药性试验结果显示,80%以上菌株对头孢曲松、妥布霉素、诺氟沙星、环丙沙星、林可霉素和甲氧苄氨嘧啶耐药,其中甲氧苄氨嘧啶耐药率达99%,对美罗培南和氟苯尼考保持高度敏感。所有测试菌株出现多重耐药,优势耐药谱为LIN/CRO/CN/T/NOR/CIP。调查结果为结肠弯曲菌防控提供参考依据。

Closing crop yield and efficiency gaps for food security and sustainable agriculture

正The world population is estimated to reach 10 billion by 2050. The rise in population coupled with improving living standards will require a doubling of the crop yield to fulfill food demand and livestock feed, which means crop yield will need to increase by 60–110% between 2005 and 2050(Tilman et al. 2011).
