Naegleria fowleri is a pathogenic amoeboflagellate most prominently known for its role as the etiological agent of the Primary Amoebic Meningoencephalitis (PAM), a disease that afflicts the central nervous system and is fatal in more than 95% of the reported cases. Although being fatal and with potential risks for an increase in the occurrence of the pathogen in populated areas, the organism receives little public health attention. A great underestimation in the number of PAM cases reported is assumed, taking into account the difficulty in obtaining an accurate diagnosis. In this review, we summarize different techniques and methods used in the identification of the protozoan in clinical and environmental samples. Since it remains unclear whether the protozoan infection can be successfully treated with the currently available drugs, we proceed to discuss the current PAM therapeutic strategies and its effectiveness. Finally, novel compounds for potential treatments are discussed as well as research on vaccine development against PAM.
福氏耐格里阿米巴是一种致病性变形鞭毛虫,最为人所知的是它作为原发性阿米巴脑膜脑炎(PAM)的病原体,这种疾病会侵袭中枢神经系统,在超过95%的报告病例中是致命的。尽管具有致命性,且在人口密集地区该病原体有增加出现的潜在风险,但该生物体很少受到公共卫生关注。考虑到获得准确诊断的困难,据推测报告的PAM病例数量被严重低估。在这篇综述中,我们总结了用于在临床和环境样本中鉴定这种原生动物的不同技术和方法。由于目前尚不清楚现有的药物能否成功治疗原生动物感染,我们进而讨论了当前PAM的治疗策略及其有效性。最后,还讨论了潜在治疗的新型化合物以及针对PAM的疫苗开发研究。
