“…Similarly, an active hemocyte-producing HPT was detected after the recovery phase in infectious hypodermal and hematopoietic necrosis (IHHN) virus-infected shrimp and after fungal infection (Hose et al, 1984;Lightner et al, 1983). In a subsequent study in Penaeus japonicas, a similar rapid increase in newly released cells with ongoing DNA synthesis was detected after LPS injection and infection with Fusarium fungi (Sequeira et al, 1996).…”

Crustacean hemocytes are important mediators of immune reactions, and the regulation of hemocyte homeostasis is of utmost importance for the health of these animals. This review discusses the current knowledge on the lineages, synthesis and differentiation of hemocytes in crustaceans. Hematopoietic tissues, their origins, and the regulation of hematopoiesis during molting, seasonal variation and infection are discussed. Furthermore, studies concerning the molecular regulation of hemocyte formation in crustaceans are also described, and the different lineages and their molecular markers are discussed and compared with several insect species. Signaling pathways and the regulation of hematopoiesis by transcription factors are typically conserved among these arthropods, whereas cytokines and growth factors are more variable and species specific. However, considering the great diversity among the crustaceans, one should be cautious in drawing general conclusions from studies of only a few species.2

“…IHHNV was first reported in P. stylirostris and P. vannamei in early 1980s in the Americas [50,51] and later in P. monodon from Asia. Eventually, it was found to have been introduced by way of live black tiger shrimp [41,43,47].…”

“…IHHNV infection caused severe mortalities up to 90 % during 1981 in cultured P. (Litopenaeus) stylirostris postlarvae and juveniles in Hawaii, which were imported from commercial hatcheries in Costa Rica and Ecuador [41,50,51]. It has been reported to cause Runt deformity syndrome (RDS) in P. (Litopenaeus) vannamei [34] and P. monodon which is a chronic, non-lethal disease [51,66]. In this review, we discuss the recent progress on IHHNV, a major viral pathogen of penaeid shrimps worldwide.…”

Infectious hypodermal and hematopoietic necrosis virus (IHHNV) is one of the major viral pathogens of penaeid shrimps worldwide, which has resulted in severe mortalities of up to 90 % in cultured Penaeus (Litopenaeus) stylirostris from Hawaii and hence designated Penaeus stylirostris densovirus (PstDNV). IHHNV is distributed in shrimp culture facilities worldwide. It causes large economic loss to the shrimp farming industry. Our knowledge about the natural reservoirs of IHHNV is still scarce. Recent studies suggest that there is sufficient sequence variation among the isolates from different locations in Asia, suggesting multiple geographical strains of the virus. Four complete genomes and several partial sequences of the virus are available in the GenBank. Complete genome information would be useful for assessing the specificity of diagnostics for viruses from different geographical areas. Comparisons of complete genome sequences will help us gain insights into point mutations that can affect virulence of the virus. In addition, because of unavailability of shrimp cell lines for culturing IHHNV in vitro, quantification of virus is difficult. The recent progress in research regarding clinical signs, geographical distribution, complete genome sequence and genetic variation, transmission has made it possible to obtain information on IHHNV. A comprehensive understanding of IHHNV infection process, pathogenesis, structural proteins and replication is essential for developing prevention measures. To date, no effective prophylactic measure for IHHNV infection is available for shrimp to reduce its impact. This review provides an overview of key issues regarding IHHNV infection and disease in commercially important shrimp species.

“…Since then, a bewildering array of viruses has been described (from electron microscopy) in species such as the blue crab by Johnson (1983) and from shrimps (Sano et al, 1981;Lightner et al, 1983). Some (but not all) of the described viruses have been associated with disease and mortality, in captivity or in culture.…”

“…Some attention is being given to that risk, but adequately documented examples of disease introductions are rare so far for marine species. Specific illustrations include introduction of a parasitic copepod (Mytilicola orientalis) from Japan to the west coast of United States with introduced Pacific oysters (Crassostrea ffigas), and the introduction of a virus disease to Hawaii (and possibly elsewhere) with introductions of penaeid shrimps from Central and South America (Lightner et al, 1983). The shrimp virus, called Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV) is highly lethal to Penaeus styh'rostris and infective to P. vannamei and P. monodon.…”

It has become almost a truism that success in intensive production of animals must be based in part on development of methods for disease diagnosis and control. Excellent progress has been made in m e t h o d s o f d i a g n o s i s for major pathogens of cultivated fish, crustacean and molluscan species. In many instances these have proved to be facultative pathogens, able to exert severe effects in populations of animals under other stresses (marginal physical or chemical conditions; overcrowding). The concept of stress management as a critical prophylactic measure is not new, but its significance is being demonstrated repeatedly. The particular relationship of water quality and facultative pathogens such as Vibrio, Pseudomonas and Aeromonas species has been especially apparent.
