Abstract

The invention relates to an avian mycoplasma culture medium, a preparation method of an avian mycoplasma solution and applications of the avian mycoplasma culture medium and the avian mycoplasma solution, and belongs to the technical field of biology. The avian mycoplasma culture medium comprises a basal culture medium and auxiliary components, wherein the basal culture medium is a conventional avian mycoplasma liquid culture medium, and the auxiliary components comprise gelatin, Tween 80 and calcium chloride; a strain for production is mycoplasma galliscepticum or mycoplasma synoviae, the avian mycoplasma solution is produced by solution inoculation, culture and harvesting, and an avian mycoplasma vaccine is prepared. According to the preparation method, antigen content of the avian mycoplasma solution is increased, production technology is simplified, production cost is reduced, probability of occurrence of vaccine immunity side effects is reduced, and vaccine immunity effect is improved.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a preparation method of a mycoplasma avium culture medium, a mycoplasma avium bacterial liquid and an application thereof. Background technique [0002] Avian Mycoplasmosis (Avian Mycoplasmosis, AM) is an infectious disease of poultry caused by Mycoplasma avium. The common clinical pathogens are Mycoplasma Gallisepticum (MG) and Mycoplasma Synoviae (MS). Mycoplasma gallisepticum infection can cause Chronic Respiratory Disease (CRD), air sacculitis and sinusitis in poultry; Mycoplasma gallisepticum infection can cause symptoms such as joint swelling, synovial bursa and tendon inflammation, and parenchymal organ enlargement; Effective vaccine immunization is the main means of preventing and controlling the disease. [0003] At present, the production of mycoplasma avium vaccine mainly uses improved Frey's medium, CM2 medium, etc. to cultivate, and these mediums have a higher s...
