Evaluation of lateral flow devices for rabies diagnosis in decomposed animal brain samples.

ABSTRACT:

Background

The Direct Fluorescent Antibody Test (DFAT), the standard rabies confirmatory test, is less sensitive when used with decomposed brain samples, a frequent issue in rabies-endemic regions. This study evaluates the diagnostic accuracy of the ADTEC lateral flow device (LFD) for rabies post-mortem diagnosis using decomposed brain samples.

Methods

We used 34 animal heads submitted with a cold chain to an animal diagnostic laboratory located in central Philippines including 26 DFAT-positive and eight DFAT-negative samples. After defrosting the heads, the entire brain was extracted and left at room temperature to induce decomposition. The decomposition status was scored after 1 day, 3 days, and 4 days at room temperature. DFAT and LFD were performed using the brain sample
