Aspergillus Galactomannan for Diagnosing Invasive Aspergillosis miceli

No abstract text is available yet for this article.

An established diagnosis of invasive aspergillus is seldom achieved premortem. Conventional laboratory diagnostic methods such as culture and microscopy, although very useful when positive, are insensitive and time-consuming, resulting in late diagnosis and treatment and contributing to high mortality rates. As a result, routine antifungal prophylaxis and early empirical treatment have been recommended. The use of sensitive and rapid non-culture-based diagnostic assays for the detection of Aspergillus antigens (using commercially available tests to detect galactomannan and 1, 3 β-D-glucan) or detection of genomic DNA sequences may allow a shift in emphasis from empirical to preemptive therapy, especially when substantiated by suggestive radiological findings...

The diagnosis of invasive fungal infections (IFI) remains a challenge, particularly for diseases caused by filamentous fungi such as Aspergillus species. Unfortunately, many patients affected by these conditions are not identified before autopsy. Therefore, there is a need for new diagnostic methods for IFI. Galactomannan is a soluble antigen released during hyphal growth in tissues. A commercially available sandwich ELISA assay that detects galactomannan has been used in Europe for many years and is now approved for use in the USA...
