Human protothecal infection is uncommon and could be localized or systemic disease. Disseminated Prototheca algaemia tends to occur in immunocompromised patients (solid organ transplants, hematological malignancies) with high mortality. Diagnosis could be missed or delayed due to unusual clinical presentation and/or under-recognition of characteristic microscopic features of Prototheca species. Combined approach that includes removal of source of infection and intravenous amphotericin B provides the best chance of cure.
人类原藻感染并不常见,可为局部或全身性疾病。播散性原藻血症往往发生在免疫功能低下的患者(实体器官移植、血液系统恶性肿瘤)中,死亡率很高。由于临床表现不寻常和/或对原藻属物种特征性微观特征认识不足,诊断可能会被漏诊或延误。包括去除感染源和静脉注射两性霉素B在内的联合治疗方法提供了最佳的治愈机会。
