Abstract
White spot syndrome virus (WSSV), Taura syndrome virus (TSV) and Infectious hypodermal and haematopoietic necrosis virus (IHHNV) are three shrimp viruses responsible for major pandemics affecting the shrimp farming industry. Shrimps samples were collected from 12 farms in Zhejiang province, China, in 2008 and analyzed by PCR to determine the prevalence of these viruses. From the 12 sampling locations, 8 farms were positive for WSSV, 8 for IHHNV and 6 for both WSSV and IHHNV. An average percentage of 57.4% of shrimp individuals were infected with WSSV, while 49.2% were infected with IHHNV. A high prevalence of co-infection with WSSV and IHHNV among samples was detected from the following samples: Bingjiang (93.3%), liuao (66.7%), Jianshan (46.7%) and Xianxiang (46.7%). No samples exhibited evidence of infection with TSV in collected samples. This study provides comprehensive information of the prevalence of three shrimp viruses in Zhejiang and may be helpful for disease prevention control in this region
