Abstract

The present invention relates to a pig's viral disease diagnosing gene chip, a preparation method using the diagnostic gene chip and an application for detecting infectious diseases.

Description

Diagnostic gene chip for pig virus disease and uses thereof
The application is the mandate Chinese patent of submitting on December 12nd, 2,002 02155408.0, and denomination of invention is divided an application for " poultry and/or disease of domestic animals diagnostic gene chip and uses thereof ".
Invention field
The present invention relates to be used to diagnose the diagnostic gene chip of virus diseases of pigs, and the purposes of utilizing the preparation method of described diagnostic gene chip and being used to detect transmissible disease.
Background of invention
In recent years, China's livestock industry has obtained the high speed development.For a long time, hindering animal husbandry development and the subject matter that influences aquaculture production is the threat that the threat that described poultry and/or domestic animal suffer from eqpidemic disease, particularly chicken and pig suffer from transmissible disease.Owing to adopted the feeding manner of intensification, the transaction circulation of chicken, pig is accelerated, and makes the transmissible disease of pig and chicken become more complicated, usually shows as multiple infective pathogen polyinfection, causes the difficulty in the medical diagnosis on disease, the also corresponding greatly increase of difficulty of prevention and cure.It is reported, in the transmissible disease of 27 kinds of chickens of investigation, two or more transmissible disease of polyinfection, account for 65.1% of case sum, wherein the concurrent infection with infectious bursal disease is maximum, and usually concurrent newcastle disease of while also merges diseases such as intestinal bacteria, infectious laryngotracheitis sometimes.Also have report, part large scale of pig farm field, Beijing piglet mass mortality at the beginning of nineteen ninety-five, mortality ratio is that the mortality ratio of 63.21%, ten age in days piglet is 100%, exactly owing to transmissible gastroenteritis of swine, epidemic diarrhea and rotavirus concurrent infection cause.
At present, there are many difficulties in the detection for above-mentioned poultry and/or the common eqpidemic disease of domestic animal.To poultry and/or domestic animal, though particularly the diagnosis of pig and chicken transmissible disease has certain methods at present, suppress (HI) method, agar diffusion method and ELISA method etc. as isolation of virus, blood clotting (HA) method, blood clotting, there is more defective in above-mentioned traditional detection method.On the one hand, because domestic animal to be measured has generally all inoculated the vaccine of described disease, so can not diagnose with the serology that detects antibody.And viral isolating method commonly used generally needs the time in one to two week just to go out the result.Also have and detect all more complicated such as viral ELISA method, fluorescent antibody technique, need the time generally to take three days, specificity and susceptibility are not as gene chip.As for the PCR method is the comparison sensitivity, causes false positive, particularly RT-PCR to be difficult to operation but be easy to pollute, and is difficult for promoting.Above-mentioned all methods can only detect a kind of cause of disease at every turn, waste time and energy, and are unfavorable for the infection of the compound infective pathogen of mass detection simultaneously.
Biochip technology is a new and high technology that develops rapidly in life science in recent years, it mainly is the miniature organism chemical analysis system that makes up on the solid phase chip surface by micro-processing technology and microelectronics, with realize pair cell, protein, DNA and other multiple biotic components accurately, fast, the detection of bulk information.Biochip commonly used is divided into three major types: i.e. gene chip, protein chip and chip lab.The principal feature of biochip is a high-throughput, microminiaturization and automatization.
The inventor is applied to poultry and/or domestic animal with above-mentioned biochip technology first, the transmissible disease detection range of chicken and pig particularly, prepared the diagnostic gene chip that to diagnose multiple cause of disease by one-time detection, thereby solved the problem that existing eqpidemic disease diagnostic techniques can not single test detects multiple cause of disease simultaneously effectively, the transmissible disease that has realized required sample size is few, sensitive, special, quick, expense is cheap poultry and/or domestic animal, particularly pig and/or chicken detects.
Summary of the invention
One aspect of the present invention relates to a kind of gene chip that is used to diagnose the poultry and/or the disease of domestic animals, and it is selected from:
