A rapid and accurate point-of-care test for invasive pulmonary aspergillosis is presented. It takes advantage of lateral-flow technology using a specific monoclonal antibody that binds to an Aspergillus antigen secreted during pulmonary infections. The assay is compatible with serum and brochoalveolar lavage and represents a novel adjunct test for disease diagnosis.

Utilizing luciferase and in vivo imaging systems (IVIS) as a novel means to identify disease endpoints before clinical developments occur. IVIS has allowed us to visualize in real time the invasion of encephalitic viruses over multiple days, providing a more accurate disease model for future study. It has also allowed us to identify the potential protective features of antivirals and vaccines faster than currently utilized animal models. The capability to utilize individual animals over...

FAQs
Reliable assessment comes from combining evidence rather than depending on one signal. Field surveillance can reveal organisms directly, traps can indicate their presence, and symptom monitoring can show characteristic damage. Remote sensing adds broader spatial observation, while DNA-based assays test for genetic signatures. Together, these approaches strengthen detection and support confirmation before spread.
Early confirmation creates a practical decision point for biosecurity. Once a suspected organism or signature is verified, authorities can choose measures such as quarantine, eradication, or targeted management instead of waiting for a larger population. The timing matters because preventing establishment or expansion can reduce damage to biodiversity, agriculture, forestry, and ecosystem services.
Each method answers a different surveillance need. Visual inspection and symptom monitoring rely on observable organisms or damage, whereas traps provide a structured way to detect presence. Remote sensing can extend observation across areas, and DNA-based assays can confirm a characteristic genetic signature. Combining methods helps compensate for the limits of any single source of evidence.
A practical workflow begins with field surveillance, followed by observations from visual checks, traps, or symptoms. Remote sensing may broaden the area examined, while DNA-based assays can be used when genetic confirmation is needed. Findings are then evaluated to support confirmation and guide quarantine, eradication, targeted management, or continued monitoring.
Tool selection depends on the surveillance need. Visual inspection and symptom monitoring focus on organisms or damage, traps provide detection points, remote sensing supports broader observation, and DNA-based assays address genetic signatures. Using these options together can improve coverage and provide complementary evidence for decisions about suspected incursions.
In environmental work, the results inform protection of biodiversity and ecosystem services, while agricultural and forestry programs use them to reduce threats to crop production and forestry. Detection records also support long-term monitoring, allowing managers to track whether a response has succeeded or whether continued surveillance is needed.
