Infectious Myonecrosis Virus (IMNV)

Infectious myonecrosis (IMN) is a viral disease of penaeid shrimp caused by myonecrosis virus (IMNV). The genome of IMNV consists of a single, double-stranded RNA molecule of 7560 bp. The principal host species in which IMNV is known to cause significant disease outbreaks and mortalities is Penaeus vannamei.

Clinical signs of infected shrimps

  • Acute phase: white necrotic areas in striated (skeletal) muscles, especially in the distal abdominal segments and tail fan, which can become necrotic and reddened similar to the colour of cooked shrimp
  • Severely affected shrimp become moribund, and mortalities can be high immediately following a “stress” event and continue for several days
  • Lethargy
  • Loss of balance
  • Swimming on water surface during day time

Mortality rate
40% to 70% of affected populations

Infected shrimp types
Penaeid shrimp

Mode of transmission
Transmitted via water and from broodstock to progeny
