The continuing emergence of multi-drug resistant pathogens has sparked an interest in seeking alternative therapeutic options. Antimicrobial combinatorial therapy is one such avenue. A number of studies have been conducted, involving combinations of bacteriocins with other antimicrobials, to circumvent the development of antimicrobial resistance and/or increase antimicrobial potency. Such bacteriocin-antimicrobial combinations could have tremendous value, in terms of reducing the likelihood of resistance development due to the involvement of two distinct mechanisms of antimicrobial action. Furthermore, antimicrobial synergistic interactions may also have potential financial implications in terms of decreasing the costs of treatment by reducing the concentration of an expensive antimicrobial and utilizing it in combination with an inexpensive one. In addition, combinatorial therapies with bacteriocins can broaden antimicrobial spectra and/or result in a reduction in the concentration of an antibiotic required for effective treatments to the extent that potentially toxic or adverse side effects can be reduced or eliminated. Here, we review studies in which bacteriocins were found to be effective in combination with other antimicrobials, with a view to targeting clinical and/or food-borne pathogens. Furthermore, we discuss some of the bottlenecks which are currently hindering the development of bacteriocins as viable therapeutic options, as well as addressing the need to exercise caution when attempting to predict clinical outcomes of bacteriocin-antimicrobial combinations.
多重耐药病原体的不断出现引发了人们对寻找替代治疗方案的兴趣。抗菌联合疗法就是这样一种途径。已经开展了多项研究,涉及细菌素与其他抗菌剂的组合,以规避抗菌耐药性的产生和/或提高抗菌效力。就降低因两种不同抗菌作用机制而产生耐药性的可能性而言,这种细菌素 - 抗菌剂组合可能具有巨大价值。此外,抗菌协同相互作用在降低昂贵抗菌剂的浓度并将其与廉价抗菌剂联合使用从而降低治疗成本方面也可能具有潜在的经济意义。此外,细菌素联合疗法可以拓宽抗菌谱和/或降低有效治疗所需抗生素的浓度,从而有可能减少或消除潜在的毒性或不良副作用。在此,我们综述了发现细菌素与其他抗菌剂联合有效的研究,旨在针对临床和/或食源性病原体。此外,我们讨论了目前阻碍细菌素成为可行治疗选择的一些瓶颈,以及在试图预测细菌素 - 抗菌剂组合的临床结果时需要谨慎行事的必要性。
