Development of silver nano-based indirect ELISA and Dot-ELISA methods for serological diagnosis of a bacterial fish pathogen Aeromonas veronii.

Rapid and accurate detection of bacterial pathogens is critical in controlling disease outbreaks affecting farmed fish. The present study aimed to develop a novel serological diagnostic approach using nano‑silver based Enzyme-linked immunosorbent assay (ELISA) for speedy detection of Aeromonas veronii infections in Nile tilapia.
