Overview

Top of page

Infectious myonecrosis is a disease of penaeid shrimp, most notably the whiteleg shrimp Litopenaeus vannamei, caused by infection with infectious myonecrosis virus (IMNV) (Poulos et at., 2006). IMNV first emerged in north-eastern Brazil, but spread to Indonesia in 2006, likely by careless importation of shrimp aquaculture stocks (Flegel, 2012; Lightner et al., 2012). IMNV causes necrosis of the skeletal muscle of distal segments and the tail fan and has resulted in large economic losses in both Brazil and Indonesia. Mortality in ponds can reach 70% (Poulos and Lightner, 2006).

Infectious myonecrosis is on the list of diseases notifiable to the World Organisation for Animal Health (OIE). For further information on this disease from OIE, see the website: www.oie.int

Hosts/Species Affected

Top of page

The principal host species in which IMNV is known to cause significant disease outbreaks and mortalities in farmed populations is the whiteleg shrimp Litopenaeus vannamei (Poulos et at., 2006). Litopenaeus stylirostris and Penaeus monodon have been infected experimentally with IMNV, but mortalities did not occur (Tang et al., 2005).

Distribution

Top of page

IMNV was first reported from Brazil, but since 2006 from Indonesia. IMNV has not been reported from other countries in Asia (Flegel, 2012).
