“xenodiagnosis”的用法和例句:
- Xenodiagnosis is a diagnostic method used to detect parasitic infections, such as Chagas disease, by allowing uninfected vectors to feed on a patient and then examining the vectors for the presence of pathogens.
(异种诊断是一种通过让未感染的媒介生物叮咬患者,然后检查媒介生物中是否存在病原体来诊断寄生虫感染(如查加斯病)的方法。)
- In areas where Chagas disease is endemic, xenodiagnosis remains a valuable tool for confirming Trypanosoma cruzi infections when other tests yield inconclusive results.
(在查加斯病流行地区,当其他检测结果不明确时,异种诊断仍是确认克氏锥虫感染的重要工具。)
- The procedure involves laboratory-bred reduviid bugs (kissing bugs) that are allowed to bite the patient; after several weeks, the bugs’ feces are tested for the parasite.
(该过程涉及实验室饲养的锥蝽(接吻虫),让它们叮咬患者;几周后,检测锥蝽的粪便中是否存在寄生虫。)
- Xenodiagnosis is particularly useful for detecting chronic Chagas disease, where parasitemia levels in the patient’s blood are too low to be identified by conventional methods.
(异种诊断对检测慢性查加斯病特别有用,因为此时患者血液中的寄生虫水平过低,常规方法难以识别。)
- Although xenodiagnosis is highly specific, it is not widely used today due to the time required (several weeks) and the need for specialized insectaries.
(尽管异种诊断特异性很高,但由于耗时(数周)且需要专门的昆虫饲养设施,如今未得到广泛应用。)
- Researchers have explored alternatives to xenodiagnosis, such as PCR-based tests, but xenodiagnosis still provides direct evidence of parasite viability.
(研究人员已探索异种诊断的替代方法,如基于PCR的检测,但异种诊断仍能直接提供寄生虫存活性的证据。)
- In the mid-20th century, xenodiagnosis played a key role in understanding the transmission cycle of Chagas disease and identifying asymptomatic carriers.
(20世纪中叶,异种诊断在理解查加斯病传播周期和识别无症状感染者方面发挥了关键作用。)
- Patients undergoing xenodiagnosis are monitored for allergic reactions to the vector bites, though severe complications are rare.
