Description
Technical field
The present invention relates to technical field of microbial detection, in particular it relates to a kind of detection Acute Hepatic pancreatic necrosis cause of disease
LAMP kit.
Background technology
Penaeus Vannmei Deaths syndrome (EarlyMortality Syndrome, EMS) is defined as urgency in Thailand
Property Hepatopancreatic necrosis it is sick (Acute HepatopancreaticNecrosis disease, AHPND).It was found out from 2009
Begin, Acute Hepatic pancreatic necrosis (AHPND) breaks out in the world.But often recognized in early stage such case by raiser
Do not drawn attention to be fry quality problem.The disease is typically after seedling is thrown 20 to 30 days, and disease spreads rapidly, and the death rate shows
Write and rise.After morbidity, prawn typically exhibits:The symptom such as lethargic sleep, apocleisis, slow-growing, color is pale, soft shell.By Acute Hepatic
The prawn death rate may be up to 100% caused by pancreatic necrosis, very harmful to shrimp farming, the first half of the year in 2011, Hainan, Fujian,
The death loss of Guangdong and some areas of Guangxi is up to 80%.International food and agricultural organization FAO statistical result showeds in 2011, Malaysia
West Asia Penaeus Vannmei and Penaeus monodon yield total output dropped to 40000 tons by 70000 tons in 2010, the region of the disease
The extent of injury has been over white spot syndrome.In Vietnam, in June, 2011, cultivating penaeus monodon industry by unprecedented loss, its
Middle Tra Vinh saves 6200 hectare of cultivation by crushing blow, dead prawn sum about 3.3 hundred million tails, direct economic loss
12000000000 Dongs(Total about 3,800,000 RMB);The north hectare of cultivation of village province 20000 is disaster-stricken, the Dong of economic loss 1,500,000,000,000
(About 4.7 hundred million RMB).
Research data shows that AHPND cause of disease is a kind of Acute Hepatic pancreatic necrosis cause of disease for carrying the plasmid PVA1 that causes a disease
Specific strain.The PVA1 plasmids carry two encoding toxin protein genes, are separately encoded PirA and PirB toxin proteins.PirA
Prawn Hepatopancreatic necrosis can be caused with PirB toxin proteins, so as to which AHPND diseases occur.At present for PVA1 plasmids or
The regular-PCR detection method of PirA and PirB toxin proteins, but such method is high for equipment and personnel requirement, cost
It can be in any more, it is difficult to promote on a large scale.
Ring mediated isothermal amplification (loop-mediated isothermal amplification, LAMP) technology is a kind of
Novel isothermal nucleic acid amplification method, improved in the technology of traditional PCR technique, devise 4 or 6 it is different special
