Infections caused by Candida species have been increased dramatically worldwide due to the increase in immunocompromised patients. For the prevention and cure of candidiasis, several strategies have been adopted at clinical level. Candida infected patients are commonly treated with a variety of antifungal drugs such as fluconazole, amphotericin B, nystatin, and flucytosine. Moreover, early detection and speciation of the fungal agents will play a crucial role for administering appropriate drugs for antifungal therapy. Many modern technologies like MALDI-TOF-MS, real-time PCR, and DNA microarray are being applied for accurate and fast detection of the strains. However, during prolonged use of these drugs, many fungal pathogens become resistant and antifungal therapy suffers. In this regard, combination of two or more antifungal drugs is thought to be an alternative to counter the rising drug resistance. Also, many inhibitors of efflux pumps have been designed and tested in different models to effectively treat candidiasis. However, most of the synthetic drugs have side effects and biomedicines like antibodies and polysaccharide-peptide conjugates could be better alternatives and safe options to prevent and cure the diseases. Furthermore, availability of genome sequences of Candida albicans and other non-albicans strains has made it feasible to analyze the genes for their roles in adherence, penetration, and establishment of diseases. Understanding the biology of Candida species by applying different modern and advanced technology will definitely help us in preventing and curing the diseases caused by fungal pathogens.
由于免疫功能低下患者数量的增加,念珠菌属引起的感染在全球范围内急剧增加。为了预防和治疗念珠菌病,临床上采取了多种策略。念珠菌感染患者通常用多种抗真菌药物治疗,如氟康唑、两性霉素B、制霉菌素和氟胞嘧啶。此外,真菌病原体的早期检测和鉴定对于给予适当的抗真菌治疗药物将起到关键作用。许多现代技术,如基质辅助激光解吸电离飞行时间质谱(MALDI-TOF-MS)、实时聚合酶链反应(PCR)和DNA微阵列,正被用于准确快速地检测菌株。然而,在长期使用这些药物期间,许多真菌病原体产生耐药性,抗真菌治疗受到影响。在这方面,联合使用两种或更多种抗真菌药物被认为是应对不断上升的耐药性的一种替代方法。此外,许多外排泵抑制剂已被设计并在不同模型中进行测试,以有效治疗念珠菌病。然而,大多数合成药物都有副作用,而抗体和多糖-肽缀合物等生物药物可能是预防和治疗这些疾病的更好选择和安全选择。此外,白色念珠菌和其他非白色念珠菌菌株的基因组序列的可用性使得分析这些基因在黏附、侵袭和疾病发生中的作用成为可能。通过应用不同的现代先进技术来了解念珠菌属的生物学特性,肯定会帮助我们预防和治疗由真菌病原体引起的疾病。
