Bacteriophages are viruses, which are obligate parasites of specific bacteria for the completion of their lifecycle. Bacteriophages could be the possible alternative to antibioticresistant bacterial diseases. With this objective, extensive research in different fields is published which are discussed in this article.
After a review of bacteriophage therapy, bacteriophages were found to be effective against the multidrug-resistant bacteria individually or synergistically with antibiotics. They were found to be more effective, even better than the bacteria in the development of a vaccine.
Apart from the bacteriophages, their cell contents like Lysin enzymes were found equally very much effective. Only the major challenge faced in phage therapy was the identification and characterization of bacteria-specific phages due to the wide genetic diversity of bacterial populations. Similarly, the threshold level of bacteriophages to act effectively was altered by ultraviolet radiation and heat exposure.
Thus, bacteriophage therapy offers promising alternatives in the treatment of antibioticresistant bacteria in different fields. However, their effectiveness is determined by a triad of bacteriophages (type & quantity), host (bacteria) and environmental factors.
噬菌体是病毒,是为完成生命周期而专门寄生在特定细菌上的必需寄生虫。噬菌体可能是对抗抗生素耐药性细菌疾病的可行选择。出于这个目的,广泛的研究在不同领域发表,本文对此进行了讨论。
在对噬菌体疗法进行审查后,发现噬菌体单独或与抗生素协同作用对多药耐药菌有效。它们被发现比细菌在疫苗开发方面更有效,甚至更好。
除了噬菌体,它们的细胞内容物,如溶菌酶,也同样非常有效。噬菌体治疗中面临的主要挑战是由于细菌种群的广泛遗传多样性,鉴定和表征细菌特异性噬菌体。同样,紫外线辐射和热暴露改变了噬菌体有效作用的阈值水平。
因此,噬菌体疗法在治疗不同领域的抗生素耐药菌方面提供了有前途的替代方法。然而,它们的有效性取决于噬菌体(类型和数量)、宿主(细菌)和环境因素的三联体。
