Reproduction of nodavirus disease was performed by experimental infection of sea bass eggs during fertilization or at larval stage 4 with 2 genetically distinguishable nodavirus strains (Sb1 and Sb2) isolated from sea bass collected along the Atlantic and Mediterranean French coast. The pathogenicity of the virus strains was assigned after detection of the virus by ELISA and immunohistochemistry (IHC). The Atlantic (Sb1) strain was more pathogenic than the Mediterranean (Sb2) strain during the fertilization step whilst both strains were pathogenic following experimental exposure of 4 d old larvae. Virus lesions developed in the brain 4 to 6 d following experimental exposure. Experimental ELISA proved very sensitive for detecting the nodavirus in Sb1 or Sb2...
