Abstract

Populations of the Pacific blue shrimp, Penaeus stylirostris, reared at the University of Arizona's experimental shrimp culture facility on Oahu in Hawaii from late 1980 through 1981, were severely affected by a highly acute and lethal disease of viral etiology. Also found to be susceptible to the disease were P. vannamei and P. monodon. The disease was named infectious hypodermal and hematopoietic necrosis (IHHN) disease to describe the principal lesions observed. The histopathology of acute and subacute IHHN disease in these species was dominated by the presence of conspicuous eosinophilic intranuclear-inclusion bodies of the Cowdry type A variety in ectodermally (especially the cuticular hypodermis) and mesodermally (especially the hematopoietic tissues) derived tissues that were undergoing necrosis. Electron microscopy of affected tissues demonstrated the presence of two or three types of virus-like particles with cubic morphology and diameters of 17 to 27 nm that suggest IHHN virus to be either a parvo- or picornavirus.
