“…Although WSSV was not detected in this study, the surveillance of this pathogen is relevant, because WSSV has been reported in more than 100 species of crustaceans, including numerous wild species [20]. Thus, early detection of a given disease is a key strategy for biosecurity and monitoring [21], because viral infections occur in all stages of the life cycle of the shrimp (eggs, larvae, post-larvae, juvenile, and adults) [21]. In natural conditions is difficult to evidence the effect of a given disease in wild populations [1].…”

A survey for Infectious Hypodermal and Haematopoietic Necrosis Virus (IHHNV) and White Spot Syndrome Virus (WSSV) was performed during two catching seasons of native shrimps in the Yucatan Coast in the Gulf of Mexico. The mtDNA COI barcode identified two endemic species; the southern pink shrimp Penaeus notialis (Pérez Fantante, 1967) and the northern pink shrimp Penaeus brasiliensis (Latreille, 1987) (previously described as Farfantepenaeus brasiliensis). The prevalence of IHHNV was of 18.18% in 2016, and of 8.57% in 2017. All organisms tested negative for WSSV. This is the first identification of wild shrimps in the state of Yucatan Mexico by mtDNA COI barcode as well as the first identification of IHHNV in such species. The presence of IHHNV in wild shrimps populations has a potential of persisting in the coast of Yucatan with putative detrimental effect on local fisheries because once established in natural waters and hosts; such pathogens are almost impossible to eradicate.

“…PL and juvenile shrimps are more susceptible to IHHNV infection than adults due to the presence of actively dividing cells [7,34,42]. IHHNVinfected females fail to develop embryos and also fail to hatch the eggs [3,59]. This virus is highly species-specific, particularly in terms of gross manifestations.…”

“…The transmission of IHHNV in the natural environment happens both by vertical and horizontal [6,41,54,[57][58][59]. The horizontal transmission of IHHNV in culture system occurs mainly through the ingestion of dead infected shrimp and by contact with water containing the virus.…”

“…This could be through the shedding of viral particles at the time of spawning and then ingestion by larvae at first feeding, or by the transmission of virus from oocytes to larvae [54]. The vertical transmission of IHHNV through female P. vannamei was confirmed by nested-PCR analysis of embryos and larvae produced by IHHNV-infected females fertilized by IHHNV-free males [59]. Zhang and Sun also reported IHHNV in ovarian tissues and fertilized egg of P. (Fenneropenaeus) chinensis [97].…”

“…A nested PCR has also been developed in India [67]. A different nested PCR based commercial kit was also developed for improved sensitivity of detection [59]. For the specific detection of infectious IHHNV, the primers IHHNV309F/R having 9-12 nucleotide mismatches with virus-related sequence can be used [83].…”

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.
