Histology of S. paramamosain challenged with WSSV. (a) Example of normal subcuticular epidermis lacking WSSV lesions and consistent with the negative PCR test kit and real time PCR results. (b) Example of a hepatopancreatic tissue lesion resembling those caused by crustacean microsporidians undergoing spore development. (c) Example of a hepatopancreatic lesion showing large eosinophilic cytoplasmic inclusions of unknown nature and also hematocytic aggregation typical of severe bacterial infections. (d) Example of small cytoplasmic inclusions adjacent to the nuclei of connective tissue cells.
