SBS-YHSV-Shrimp
Yellow Headed Syndrome Virus (Shrimp)
This disease caused by the yellow headed virus(YHV) a positive sense single stranded RNA virus related to coronavirus and arteriviruses. A closely related virus is the gill-associated virus(GAV),which is the type species of the genes okavirus.
YHSV leads to death after 2-4 days, YHSV is a viral infection of shrimp and prawn
HISTORY:- First detected in 1990 Thailand and in Australia 1995 in formed fields and spread through out the World.
FAMILY:-Roniviridae
SPECIES:-YELLOW HEAD VIRUS
PHYLUM:-pisurivicota
GENUS:-Okavirus
This disease is named because of change in the appearance of hepto pancreas from brown to yellow.
TREATMENT:-
-
Treatment consists of binding to the -COOH end of the single strand RNA. Genetic silencing to Next generation.
-
Already existing reproductive protein denaturation.
-
Observed change of color within 8 Hrs from yellow to brown.
YHSV Caused to both shrimps and prawn:-
Crustaceans may have several common names but only one common name is provided in this list. Note: the terms "shrimp" and "prawn" can both be used.
-
Euphausia superba (Antarctic krill)
-

-
Yellow head disease is a RNA based viral disease related to coronaviruses and arteriviruses which occurs in species like Penaeus monodon (giant tiger prawn).
-
YHD is a highly lethal, and contagious, killing shrimp quickly.
-
This disease is caused by Yellow head virus(YHV).
-
Prevention/Treatment: New molecule is invented which prevents/cure by virucidal and virustatic activities.
-
The spread of the disease is controlled by Virustatic and virucidal activities performed by the same molecule.
-
This molecule can be administered as aqua feed supplement .
-
For Each viral cycle terms wise doses can be administered to prevent YHD in shrimp culture .
-
This leads to stress relieving to the shrimp where YHD is a stress related disease.
-
We have screened 900 new molecules and selected 1 molecule among them to prevent and control YHD.
-
Prevention consists of treating each viral cycle, we are treating the shrimp to free from YHV and whenever shrimp is effected with YHV.
-
The Dosage can be customized to suit specific pond/area/country salinities
