Identification of identification of Hepatopancreatic Parvo-like Virus (HPV) in cultured Penaeus semisulcatus from the Islamic Republic of Iran

During the period from August ۱۹۹۷ to March ۱۹۹۸, two thousand samples of cultured Penaeus semisulcatus postlarvae and subadults were collected from five hatcheries and ۲۰ growout farms distributed in three provinces along the costs of Persian Gulf and the Oman Sea. Based on growth signs, LM and TEM histopathology, Hepatopancreatic Parvo-like Virus (HPV) were identified from the samples. The HPV particles most often appeared in spherical, but occasionally in angular forms. The particles in hepatopancreatocyte sections, averaged ۲۲-۲۴nm in diameter.
