Abstract

The invention discloses a PCR diagnostic kit for porcine infectious pleuropneumonia, which comprises 400mu L of proteinase K with the concentration of 20mg / mL, 1000mu L of cracking solution, 1500mu L of TE buffer solution, 250mu L of PCR enzyme, 170mu L of ultra-pure water, 50mu L of MarkerDL2000, 40mu L of primer P1 and primer P2 which are mixed in the same volume and have the same concentration of 20mu M, 20mu L of negative control and 20mu L of positive control. By optimizing the PCR reaction conditions, the invention develops a PCR kit for detecting the actinobacillus of the porcine infectious pleuropneumonia; and by comparing the PCR detection result with the negative control and the positive control, detection conclusions can be obtained, thereby achieving the aim of quickly detecting whether a sample has porcine infectious pleuropneumonia or not. The invention has accurate detection result, quick and sensitive detection process, simple detection mode and good using effect.

Description

technical field [0001] The invention relates to a kit, in particular to a PCR diagnostic kit for porcine infectious pleuropneumonia. Background technique [0002] Porcine Contagious Pleuropneumoniae (PCP) is a porcine respiratory disease caused by Actinobacillus Pleuropneumoniae (APP), characterized by hemorrhagic, necrotizing pneumonia and chronic fibrinous pleuropneumonia. Pigs die or grow poorly, causing huge economic losses to the swine industry around the world (Sebunya T N K et al., 1983, Macinnes J L et al., 1988, Gram T et al., 2000). It became popular in our country in the 1980s, and has become widely popular in recent years and has become an upward trend. According to whether it depends on NAD, it can be divided into two biotypes: biotype I and biotype II. The serotypes 1, 5, 9, and 10 of biological type I are the most pathogenic. According to statistics, the popular serotypes in my country are 1, 2, 3, 5, 7, 10 and other types, with 1, 3, and 7 being the main t...
