Effect of Livestock Manure on Antibiotic-Resistant Endophytic Bacteria in Vegetables

摘要：
选取常食农田茎叶类蔬菜——上海青和芹菜为研究对象,探讨禽畜粪肥对蔬菜抗生素抗性内生菌的影响.结果表明:施加粪肥的农田上海青及芹菜样品的根、茎、叶中抗阿莫西林、头孢氨苄、四环素的单抗性内生细菌的数量均比未施加粪肥组高,它们的相对百分比含量比未施加组高出9~19倍.其中,从施加禽畜粪肥上海青中分离获得的多重抗生素抗性细菌-嗜麦芽寡养单胞菌,可能引起多种人类疾病,尤其值得关注.
In this paper, we investigated the effects of application of livestock manure on antibiotic-resistant endophytic bacteria in pakchoi and celery wl^ich are often consumed as popular stems and leafy Vegetables. The result indicated that the count and proportion of endophytic bacteria resistant to Amoxicilln trihydrade, Cephalexin monohydrate or Tetracyclin Hydrachloride in root, stem and leaf of manure-fertililzed pakchoi and celery was 9-19 folds higher than that in manure-free pakchoi and celery. Notably, Stenotrophomonas rnaltophilia of these bacteria is an opportunistic pathogen to humans and can cause various disease infections.
