Embodiment 1
[0027] Embodiment 1 Akkermansia muciniphila bacterial agent preparation
[0028] Preparation of active bacterial agents: Akkermansia muciniphila BAA-835 was cultured strictly anaerobically in brain heart infusion medium supplemented with 2% (m / v) type III mucin. Centrifuge the bacterial solution in the logarithmic growth phase at 4°C and 8000g for 10 minutes, remove the supernatant, wash the bacterial sludge twice with sterile physiological saline, and resuspend the bacterial sludge in glycerol with a volume fraction of 30% (v / v) , optionally, it can be stored in a -80°C refrigerator.
[0029] Preparation of inactivated bacteria: Akkermansia muciniphila BAA-835 was cultured strictly anaerobically in brain heart infusion medium supplemented with 2% (m / v) type III mucin. Centrifuge the bacterial solution in the logarithmic growth phase at 4°C and 8000g for 10 minutes, remove the supernatant, wash the bacterial sludge twice with sterile physiological saline, and resuspend the ba...
Embodiment 2
[0031] Embodiment 2 The preparation of the medicine containing Akkermansia muciniphila
[0032] The bacterial suspension containing Akkermansia muciniphila BAA-835 living cells or inactivated cells prepared in Example 1 is mixed with the auxiliary materials to obtain a liquid preparation; optionally, compression molding is made into tablets; alternatively, the liquid The formulation is dried to obtain a powder; alternatively, the powder is used as a filling to prepare capsules.

Embodiment 3
[0034] Example 3 Akkermansia muciniphila BAA-835 for the treatment of chronic pancreatitis
[0035] (1) Establishment of chronic pancreatitis model:
[0036] 8-week-old 20-23g female C57BL / 6J mice were randomly divided into control group (CON), inflammation model group (CAE), Akkermansia muciniphila BAA-835 live bacteria treatment group (CAE+L), Akkermansiamuciniphila BAA-835 Pasteurized inactivated bacteria treatment group (CAE+K), 8 animals in each group, provided controlled feeding conditions. The chronic pancreatitis model was induced by intraperitoneal injection of cerulein. Dissolve cerulein in normal saline, inject cerulein (50 μg / kg body weight) every hour for 6 consecutive injections, three days a week for four weeks. Mice in the CON group were given an equal volume of saline. During the modeling period, each mouse in the CAE+L group was given 5×10 3% glycerol by intragastric administration every day. 9CFU / mL of Akkermansia muciniphila live bacteria solution 200 μ...
