Infectious myonecrosis is a viral disease caused by infectious myonecrosis virus. It affects Pacific white shrimp Penaeus vannamei, tiger shrimp P. monodon and blue shrimp P. stylirostris. IMN is associated with heavy losses in farmed shrimp of 40-70%. Originally reported from Brazil, outbreaks were first reported in Indonesia in May 2006. With the current spread of the disease there is a high threat of the disease spreading to neighbouring P. vannamei-producing countries.
