Prevalence of Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV) in Farmed Procambarus clarkii of the Middle and Lower Reaches of the Yangtze River in China.

ABSTRACT: Procambarus clarkii is an important economic aquaculture species worldwide. Infectious hypodermal and hematopoietic necrosis virus (IHHNV) infects numerous crustacean hosts, including P. clarkii. However, there have been few reports on the prevalence of IHHNV in P. clarkii. In this study, 200 farmed P. clarkii were collected from Anhui, Jiangsu, Zhejiang, Hunan, Hubei, and Sichuan provinces in China. PCR detection was employed per the protocol by the World Organization for Animal Health (WOAH) to identify and detect the presence of IHHNV. The positive rate of IHHNV in different provinces ranged from 16.7 to 56.7%, and the overall IHHNV-positive rate was 38.5%. IHHNV strains isolated in this study related closely to infectious IHHNV and split into two major disti
