Overview

Top of page

Necrotising hepatopancreatitis (NHP) is a disease of penaeid shrimp caused by infection with a Gram-negative, pleomorphic intracellular alphaproteobacterium (Lightner et al., 1992; Loy et al., 1996) preliminarily called “Candidatus Hepatobacter penaei” (Nunan et al., 2013), also known as necrotizing hepatopancreatitis bacterium (NHPB).

NHPB resides and multiplies in the epithelial cells of the hepatopancreas of several penaeid species, and has caused significant disease outbreaks and mortalities in farmed shrimp, particularly the whiteleg shrimp Litopenaeus vannamei (Lightner and Redman, 1994; Ibarra-Gámez et al., 2007). First reported in 1985 in a Texas shrimp farm (Frelier et al., 1992), NHP is considered as a serious problem for the shrimp farming industry in the Western Hemisphere (reviewed by Gollas-Galván et al., 2014).

Necrotizing hepatopancreatitis 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

Distribution

Top of page

NHPB appears to have a Western Hemisphere distribution (Lightner et al., 2012). The bacterium has caused significant disease outbreaks and mortalities in farmed shrimp in the Americas (reviewed by Gollas-Galván et al., 2014).
