Pathogen Characteristics

Top of page

Necrotizing hepatopancreatitis bacterium (NHPB) is a pleomorphic, rickettsia-like obligate intracellular pathogen of Litopenaeus vannamei, the whiteleg shrimp, that cannot be cultivated in cell-free media (Loy et al., 1996). The geographic range is limited to the Western Hemisphere (Lightner et al., 2012). The Gram-negative organism is motile by means of eight flagella located at the basal apex. The bacteria present two morphological variants consisting of a rod-shaped organism (0.25 by 0.9 μm) and a helical form (0.25 by 2 to 3.5 μm). Phylogenetic analysis, inferred from 16S rRNA and gyrase B gene sequences, places this bacterium within the order Rickettsiales. The proposed classification of NHPB is “Candidatus Hepatobacter penaei” (Nunan et al., 2013).
