Abstract

The invention relates to an in vitro diagnostic reagent and a preparation method thereof and in particular relates to a rapid detection kit for drug susceptibility of mycoplasma bovis and a preparation method of the rapid detection kit. The invention provides the rapid detection kit for the drug susceptibility of the mycoplasma bovis; the kit comprises a mycoplasma culture solution, a drug susceptibility plate and an antibiotic drug. The mycoplasma culture solution is prepared from the following components according to the content: 10 to 15g of PPLO (Pleuropneumonia-like Organism) powder, 2 to4g of oligopeptide, 100 to 500mg of morroniside, 2 to 6g of yeast powder, 1 to 3g of glucose, 1.5 to 4.5g of sodium pyruvate, 80 to 120mL of an MEM culture medium, 2mL of a 1 percent (w / v) phenol redsolution, 100 to 300mL of horse serum, 0.3 million units of penicillin and 700 to 800mL of ddH2O. The culture solution provided by the invention can be used for rapidly promoting the growth of the mycoplasma bovis and detection can be finished within 20 to 24h; the rapid detection kit has stable performance and strong specificity.

Description

technical field [0001] The invention relates to an in vitro diagnostic reagent and a preparation method thereof, in particular to a rapid detection kit for drug sensitivity of Mycoplasma bovis and a preparation method thereof. Background technique [0002] Mycoplasma bovis (mycoplasma bovis) is one of the important pathogens that cause mastitis, calf pneumonia and arthritis in adult cows. It is highly contagious and often mixed with other pathogenic bacteria, seriously threatening the health of cattle. caused huge economic losses. Mycoplasma bovis was first isolated from the milk of cows with mastitis in 1961. Since the first report of mycoplasma pneumonia in my country in 2008, there have been cases of mycoplasma pneumonia deaths in calves and cases of mycoplasma mastitis in adult cows in cattle farms. . The incidence of the disease is high, improper treatment or death of calves, often mixed with other bacteria or viruses, the clinical symptoms are complex and diverse, so ...
