Purification and characterization of infectious myonecrosis virus of penaeid shrimp.
The causative agent of myonecrosis affecting cultured Penaeus vannamei in Brazil was demonstrated to be a virus after purification of the agent from infected shrimp tissues. Purified viral particles were injected into specific pathogen-free P. vannamei, resulting in a disease that displayed the same characteristics as those found in the original shrimp used for purification. The virus was named...
متن کاملCharacterization of newly revealed sequences in the infectious myonecrosis virus genome in Litopenaeus vannamei.
Infectious myonecrosis virus (IMNV) causes significant economic losses in farmed shrimp, where associated mortality in ponds can reach 70 %. To explore host/pathogen interactions, a next-generation sequencing approach using lymphoid organ tissue from IMNV-infected Litopenaeus vannamei shrimp was conducted. Preliminary sequence assembly of just the virus showed that there were at least an additi...
متن کاملHistoric emergence, impact and current status of shrimp pathogens in Asia.
It is estimated that approximately 60% of disease losses in shrimp aquaculture have been caused by viral pathogens and 20% by bacterial pathogens. By comparison, losses to fungi and parasites have been relatively small. For bacterial pathogens, Vibrio species are the most important while for viral pathogens importance has changed since 2003 when domesticated and genetically selected stocks of t...
متن کاملCurrent Status of Viral Diseases in Asian Shrimp Aquaculture
The giant or black tiger shrimp, Penaeus monodon, was formerly the dominant cultured shrimp species in Asia. Since approximately 2002, it has been essentially replaced by the domesticated American whiteleg shrimp P. vannamei. The change in dominant species has affected disease concerns. For both species, white spot syndrome virus (WSSV) and yellow head virus (YHV) are the most lethal. For P. mo...
متن کاملPrevalence of Two Economically Significant Viral Pathogens Wssv and Ihhnv in Farming Systems of the Exotic Shrimp Species Penaeus Vannamei (boone, 1931) in Southeast Coast of India
Penaeus vannamei (Pacific white legged shrimp), is an exotic shrimp species introduced to India in 2009, and is currently been extensively cultured along the Southeast coastal region of the Country. The expansion of the industry had resulted in mushrooming up of unapproved hatcheries and farms which do not implement adequate biosecurity measures or good management practices required for farming...
