Description

technical field

[0001] The invention belongs to the field of culture medium, in particular to a medium for efficiently cultivating Haemophilus paragallinitis gallinarum, and also relates to a preparation method and application of the medium. Background technique

[0002] Haemophilus paragallinarum is a Gram-negative bacillus, which is one of the important opportunistic pathogenic bacteria and hospital-acquired infection bacteria. Haemophilus paragallinitis caused by it is a contact infectious disease that harms poultry and wild birds such as chickens, turkeys and pheasants. The morbidity and mortality of the disease are usually 10 to 30%, but some chicken farms infected with Haemophilus paragallinitis have a mortality rate as high as 75%. Once Haemophilus paragallinitis infection occurs in chicken flocks in a certain area, the disease will become an endemic disease, which is difficult to completely eradicate, and often breaks out repeatedly, causing huge economic losses.
