摘要:
NDM-5基因是在动物源细菌尤其是鸡源大肠杆菌中主要流行的碳青霉烯类耐药基因,携带该基因的菌株呈现多重耐药性,传播能力强,被称为“超级细菌”。本研究以携带NDM-5基因的鸡源大肠杆菌SQ-C-E5为宿主菌,从污水中分离了对该细菌具有裂解作用的噬菌体,命名为vB_EcoM_Bp5。通过透射电镜观察,最佳感染复数测定,一步生长曲线绘制,杀菌试验,热稳定性及酸碱稳定性测定等试验分析该噬菌体的生物学特性。结果表明,该噬菌体为肌尾病毒科,其噬菌斑透亮,无晕圈,最佳感染复数为10,潜伏期为5 min,爆发期为65 min,该噬菌体在温度为30~60 ℃和pH为5~10时较稳定,并且噬菌体vB_EcoM_Bp5的裂解谱较广,对多株NDM-5阳性和阴性大肠杆菌都具有裂解作用。因此,噬菌体vB_EcoM_Bp5在防治携带NDM-5基因的大肠杆菌方面具有潜在应用价值。
Abstract:
NDM-5 gene is the most prevalent carbapenem resistance gene in bacteria of animal origin, especially Escherichia coli from chicken. The strains carrying the NDM-5 gene showed multidrug resistance and were easy to be spread, which were known as “superbug”. In this study, the E. coli SQ-C-E5 carrying NDM-5 from chicken was used as the host strain to isolate the lytic phage from the sewerage. The phage was designated vB_EcoM_Bp5 and its biological characteristics were analyzed by a series of test including transmission electron microscope, multiplicity of infection (MOI), one-step growth curve, bactericidal test, thermal tolerance and pH tolerance test. The results showed that the phage belonged to Myoviridae family and could form transparent plaque. The optimal multiplicity of infection(MOI) was 10, the latent period and burst period were 5 min and 65 min, respectively. The phage was stable when the temperature ranged from 30 ℃ to 60 ℃ and pH ranged from 5 to 10. Phage vB_EcoM_Bp5 had a wide host range and could lyse many NDM-5-positive E. coli isolates. Therefore, phage vB_EcoM_Bp5 has potential application value in the control of E. coli carrying NDM-5 gene.
