Abstract
Organically raised swine had high fecal populations of chlortetracycline (CTC)-resistant (growing at 64 μg CTC/ml) Escherichia coli, Megasphaera elsdenii, and anaerobic bacteria. By comparison, CTC-resistant bacteria in feral swine feces were over 1,000-fold fewer and exhibited lower taxonomic diversity.
摘要
有机养殖的猪粪便中含有大量对氯四环素（CTC）具有耐药性的（在 64μg CTC/ml 下生长）大肠杆菌、巨球形菌属和厌氧菌。相比之下，野猪粪便中的 CTC 耐药菌要少 1000 多倍，且具有较低的分类多样性。
