Embodiment 1
[0013] The isolation and identification of embodiment 1 pathogenic bacteria
[0014] According to literature reports, there are three main pathogenic bacteria of turtle bacteriosis: Aeromonas sobria, Aeromonas hydrophila and Aeromonas caviae. Dying Chinese soft-shelled turtles suffering from typical symptoms of bacterial diseases such as red neck disease, perforation disease, rotting skin disease, red floor disease, and white floor disease were selected from several turtle farms in Yueyang and Changde, Hunan, as test materials. A total of 36 strains of the above three bacteria were identified, and 3 strains of bacteria were randomly selected for cultivation for further experiments.
Embodiment 2
[0015] The preparation of embodiment 2 Chinese medicine composition
[0016] Eucommia leaf water extract: provided by Hengxing Biological Company, Zhangjiajie City, Hunan Province. (The content of chlorogenic acid is up to 8%, and it is obtained by extracting Eucommia leaves as raw materials and using water as a solvent.
[0017] Jiuliguang water extract: take the dried stems and leaves (10kg) of the herbal medicine Jiuliguang plant as raw materials, pulverize them with a pulverizer, pass through a 60-mesh sieve, add 25Kg of distilled water and soak at room temperature for 30 minutes, add steam to heat to boiling, maintain boiling and soak for 40 minutes minutes, filtered, concentrated, and spray-dried to obtain 952 grams of light yellow powder.
[0018] The water extract of Jiuliguang and the water extract of Eucommia leaves are fed according to the weight ratio of 5:2, mixed by a small powder mixer, and the traditional Chinese medicine composition of the present invention i...
Embodiment 3
[0019] Embodiment 3 in vitro antibacterial test
[0020] Three strains of Aeromonas sobria, Aeromonas hydrophila and Aeromonas caviae were tested, all of which were isolated from the diseased soft-shelled turtle. Inoculate the strain in the broth culture solution, culture at 28°C for 24 hours, culture on a plate, and then dilute with sterile saline to contain 10 bacteria 6 CFU / ml, put in the refrigerator for later use.
[0021] The test drug is now dissolved in appropriate amount of distilled water to dissolve the composition of ① Eucommia leaf water extract ② Jiuliguang water extract ③ Jiuliguang water extract: Eucommia ulmoides leaf water extract = 5: 2, and then use broth culture solution respectively Proportionally diluted to prepare culture solutions containing extracts with different concentrations.
[0022] For the antibacterial test, a 40-well tissue culture plate was used, and 190 μl of culture solution with different drug concentrations and 10 μl of bacterial solut...
