牲畜使用抗生素后体内产生的耐药基因可以转至人类病原体内吗?这个长期以来困扰人类的难题不久将会得以解决,因为分子生物学技术的发展可以帮助识别源自家畜的耐药基因。目前耐药性问题越来越严重,大多数学者认为滥用抗生素是其主要原因。当发生轻度感染而影响牲畜生长发育时,抗生素就被常规地加入到饲料中,从而导致定植或感染动物的细菌产生耐药性。现已
Can livestock-derived resistance genes be transferred into human pathogens after the use of antibiotics? This long-standing problem of humankind will soon be resolved because advances in molecular biology can help identify drug-resistant genes from livestock. At present, the problem of drug resistance is getting more and more serious. Most scholars think that abuse of antibiotics is the main reason. Antibiotics are routinely added to feed when mild infections occur which affect the growth and development of livestock, resulting in resistance to bacteria colonizing or infecting animals. Now
