摘要:

泰乐菌素是中国养殖业广泛使用的抗菌促生长类兽用抗生素之一,它进入畜禽体后,其原形和代谢产物会随畜禽粪尿进入环境,与环境微生物产生互作效应,由此本文首先介绍了环境介质中泰乐菌素残留现状,然后综述了泰乐菌素与土壤微生物的互作效应。目前畜禽生产中使用的泰乐菌素是泰乐菌素A、B、C和D的混合物,其中泰乐菌素A占80%以上,因此泰乐菌素A也是泰乐菌素在环境中残留的主要形式,但在不同环境条件下,泰乐菌素A可转化为泰乐菌素B、C和D,而且已有研究表明在畜禽粪便、污水、土壤及水体等环境介质中均检测到泰乐菌素A及其代谢产物的残留。土壤中残留的泰乐菌素可与微生物产生互作效应,即一方面泰乐菌素可影响土壤中微生物的数量、群落结构和功能;另一方面土壤微生物在受到泰乐菌素胁迫时会产生和传播耐药基因以及可降解泰乐菌素微生物等。笔者还对今后该领域的研究进行了展望。

Abstract:

Tylosin (TYL) is one of the veterinary antibiotics which were widely used in animal husbandry in China.After absorbed by animal,the prototype and metabolites of TYL were excreted with urine and manure,which resulted in negative effect on the environmental microorganism.Firstly this article introduced the residue of TYL and its metabolites in the environmental medium as animal waste,soil and water.TYL was a mixture of Tylosin A (TYLA),Tylosin B (TYLB),Tylosin C (TYLC),and Tylosin D (TYLD),with TYLA been the major component accounting up to 80% to 90% of TYL,so TYLA was the main form of tylosin residues in the environment.But TYLA could be converted into TYLB,TYLC and TYLD in the different environmental conditions.Secondly this article summarized the interaction effects of tylosin residues with soil microorganism,including the impact of the TYL residues on the number,structure,and function of soil microorganism,and the adaption of soil microorganism to the TYL residues as the degradation of TYL residues,and the generation and transmission of antibiotic resistance genes.Finally the shortage of present research and direction of future research were also prospected.
