Description
Technical field
A kind of the invention belongs to animal virology and technical field of molecular biology, more particularly it relates to fluorescence
The primer of quantitative PCR detection bacillus rhusiopathiae suises, probe, test kit and method.
Background technology
Pig erysipelas are acute, the hot infectious disease of the one kind being caused by bacillus rhusiopathiae suises, and it is mainly characterized by hyperpyrexia, acute loses
Mass formed by blood stasis, skin rash block (subacute), chronic libman-Sack endocarditis and cutaneous necrosis and multiple non suppurative arthritis.Primary disease was once
Through being referred to as one of China's " three big infectious disease ", in recent years, gradually fade out the regarding of people with intensivization development pig erysipelas of raising pigs
Open country, but this disease is not cleaned completely, and area has fragmentary appearance always throughout the country, causes serious warp to pig farmer
Ji loss.
In Swine Production, conventional pig erysipelas attenuated vaccine strain carries out immune prevention and control, effect is significant to pig erysipelas.In recent years, in
Herd, release one after another swine fever, pig erysipelas, pig lung plague three of the vaccine producer such as Guangdong Yongshun is lived Seedling, a shot can prevent 3 kinds of biographies
Catch an illness, effect is close with 3 kinds of single Seedlings, simple and effective.However, because pig erysipelas are similar with pig lung plague pasteurellosis bacilluss nutritional need,
Two kinds of antibacterials are cultivated in same culture dish and interfere, and it is inaccurate that this will result in trigeminy vaccine finished product vaccine antigen content detection,
And attenuated vaccine is higher to antigen content requirement, antigenic content is low to cause immune efficacy low, and antigenic content height then can affect
The safety of vaccine.
Generally using viable bacteria culture counting method, the bacterium number containing in vaccine is measured in prior art, concrete grammar
For：With normal saline, vaccine is diluted to after 1 part/milliliter, takes 1 milliliter to do 10 times and be serially diluted, each dilution factor changes one
Vaccine is rule of thumb diluted to corresponding multiple by dilution tube, selects suitable dilution bacterium solution inoculation blood agar culture
Base flat board 3,0.1 milliliter of each plate, cultivate 24～48 hours, perusal bacterium colony, and in flat board ground points, calculate 3
The average colony number of flat board, is multiplied by extension rate and is multiplied by 10 again, the total bacteria count contained by as every part vaccine.
The method major defect that viable bacteria cultivates counting method is that the detection used time is longer, and same vaccine has two kinds of nutritional needs similar
Antigen, then can interfere.Detection duration is because needing to do antibacterial culturing, needs 24～48 hours；After vaccine dilution
Inoculation plating medium is it is impossible to determine inoculation position, two bacterium colonies overlap or cover, then be unable to accurate counting.In addition, it is thin
There is potentially danger in bacterium culture.
In sum, detection bacillus rhusiopathiae suises content that is simply accurate in the urgent need to one kind, not disturbed by other antibacterials
Detection method.Quantitative fluorescent PCR is so that high specificity, sensitivity is high, reproducible, fireballing plurality of advantages becomes molecular biosciences
Learn the important tool in research, because it detects specific nucleic acid, therefore testing result will not be affected by other cause of diseases, can be applicable to
The content detection of bacillus rhusiopathiae suises.
