The invention belongs to the technical field of biotechnology and relates to the sequences of five oligonucleotide aptamers for specifically identifying staphylococcus aurei and use thereof. The fivesinge-chain DNA oligonucleotide aptamers for specifically identifying the staphylococcus aureus are obtained by a bacterial subtraction SELEX technology. After FITC is marked, the five aptamers are proved by fluorescent staining to be capable of specifically identifying the strain of the staphylococcus aurei. After being used in combination, the five ligands can improve sensibility in identification of target bacteria and the ratios of detected different staphylococcus aureus strains and the detected staphylococcus aurei in different growth states. Therefore, the sequences of the five aptamershave wide application prospects in quick detection of the staphylococcus aurei in samples including suspected terrorist attack biological agents and identification of the staphylococcus aurei and other gram-positive cocci.

An extraction method of the fly intestinal microorganism total DNA (deoxyribonucleic acid) relates to the technical field of experiment of molecular biology. The phenol-chloroform method is the traditional method for extracting bacterial DNAs, but the method is generally used in the DNA extraction of pure bacteria cultured in the laboratory. As the matrix ingredients and microorganisms of the environment sample are more complicated, the phenol-chloroform method and the kit method have the defects such as low cell lysis rate and large DNA loss when used for extracting total DNA; and the residual enzyme inhibitor in the extract can affect the subsequent polymerase chain reaction (PCR) amplification effect and the enzymatic reaction effect. Therefore, the extraction method is improved in the aspects such as the sample pretreatment, the operating step and the reagent solution; and in the method, the sodium-tris-EDTA (STE) buffer is used to pretreat the sample and lysozyme is used to ensure the completely splitting of Gram-positive cocci. When the fly intestinal microorganism total DNA extracted by the method is used for PCR amplification and 16S rRNA (ribosomal ribonucleic acid) library construction, the effect is better than that of domestic and import kits. The operating steps of the method are simple, and the pollution of the operating process to the sample and the damage of the operating process to DNA molecules can be effectively reduced.
