Pathogenic bacterium immunity detection chips

The utility model provides a pathogenic bacterium immunity detection chip, comprising a carrier. The carrier is provided with bacterial antibody probes which are fixed by chemical groups of amino or aldehyde groups and are different from each other, and the bacterial antibody probes are arranged in array on the carrier. The utility model carry out direct detection to a sample without pretreatment, separation or cultivation; when simultaneously detecting various bacteria in a sample, the bacteria need to be separated from each other. Only sample supernatant liquid need to be added to the carrier which is dressed with antibody; after incubation of 10-50 minutes, the species of the bacteria can be determined according to the bacteria combined on corresponding antibody of each point in order to carry out correct evaluation the bacteria containing condition of the sample. The result obtained by the utility model can detect whether the sample contains bacteria and can report the number of the species of the bacteria contained in the sample, so no further bacteria species identification is needed. The result is reliable, the detection is labor-saving and time-saving, the detecting speed is fast, and the pathogenic bacterium immunity detection chip can realize high-throughput detection.
