Representavive photomicrographs of viral antigen positive cells (green) in different tissues of moribund and dead shrimp. WSSV was detected by IIF using a VP28-specific mouse monoclonal antibody and an FITC-conjugated goat-anti mouse IgG. The cells of connective tissue (CT) of the midgut were WSSV positive, while the epithelial cells (EP) were WSSV negative.
