Abstract

Shiga toxin-producing (STEC) is a global foodborne bacterial pathogen that is often accountable for colon disorder or distress. STEC commonly induces severe diarrhea in hosts but can cause critical illnesses due to the Shiga toxin virulence factors. To date, there have been a significant number of STEC serotypes have been evolved. STECs vary from nausea and hemorrhoid (HC) to possible lethal hemolytic-based uremic syndrome (HUS), thrombotic thrombocytopenic purpura (TTP). Inflammation-based STEC is usually a foodborne illness with Shiga toxins ( and ) thought to be pathogenesis. The STEC's pathogenicity depends significantly on developing one or more Shiga toxins, which can constrain host cell protein synthesis leading to cytotoxicity. In managing STEC infections, antimicrobial agents are generally avoided, as bacterial damage and discharge of accumulated toxins are thought the body. It has also been documented that certain antibiotics improve toxin production and the development of these species. Many different groups have attempted various therapies, including toxin-focused antibodies, toxin-based polymers, synbiotic agents, and secondary metabolites remedies. Besides, in recent years, antibiotics' efficacy in treating STEC infections has been reassessed with some encouraging methods. Nevertheless, the primary role of synbiotic effectiveness (probiotic and prebiotic) against pathogenic STEC and other enteropathogens is less recognized. Additional studies are required to understand the mechanisms of action of probiotic bacteria and yeast against STEC infection. Because of the consensus contraindication of antimicrobials for these bacterial pathogens, the examination was focused on alternative remedy strategies for STEC infections. The rise of novel STEC serotypes and approaches employed in its treatment are highlighted.

摘要

产志贺毒素(STEC)是一种全球性的食源性病原体,通常会引起肠道紊乱或不适。STEC 通常会导致宿主严重腹泻,但由于志贺毒素的毒力因子,也可能导致严重疾病。迄今为止,已经有大量的 STEC 血清型进化而来。STEC 从恶心和痔疮(HC)到可能致命的溶血性尿毒症综合征(HUS)、血栓性血小板减少性紫癜(TTP)不等。基于炎症的 STEC 通常是一种食源性疾病,认为 Shiga 毒素(和)是发病机制。STEC 的致病性在很大程度上取决于产生一种或多种 Shiga 毒素,这些毒素可以抑制宿主细胞的蛋白质合成,导致细胞毒性。在管理 STEC 感染时,通常避免使用抗菌药物,因为细菌损伤和积累毒素的释放被认为是机体的自我保护机制。也有记录表明,某些抗生素会提高毒素的产生和这些物种的发展。许多不同的团体已经尝试了各种治疗方法,包括以毒素为重点的抗体、基于毒素的聚合物、共生剂和次生代谢物治疗方法。此外,近年来,人们重新评估了抗生素治疗 STEC 感染的疗效,其中一些方法令人鼓舞。然而,共生有效性(益生菌和益生元)对致病性 STEC 和其他肠道病原体的作用尚未得到充分认识。需要进一步的研究来了解益生菌和酵母对抗 STEC 感染的作用机制。由于对抗这些细菌病原体的抗生素存在共识禁忌,因此检查的重点是替代治疗 STEC 感染的策略。强调了新型 STEC 血清型的出现及其治疗方法。
