Brucella can cause brucellosis, or brucellosis for short, which is a zoonotic, chronic, contagious and harmful disease. When the immune function is sound, the general brucellosis cure can completely remove the bacteria. When the immune function is not sound, the bacteria may be lifelong, easy to relapse.
1. Sound immune function: brucellosis is caused by Brucella infection, invades the human body through skin or mucous membrane, grows and reproduces in human cells, and forms local primary lesions. When the immune function is normal, the germs can be cleared through active treatment, cellular immunity and humoral immunity to achieve the state of being cured without carrying the germs in the body.
2. Inadequate immune function: when the immune function of the body is defective, even after the cure, part of the bacteria are swallowed by phagocytes can be brought into the tissues and organs to form new foci of infection, easy to recur and may become chronic infection, which may be lifelong with bacteria.
When suffering from brucellosis, it should be actively treated under the guidance of doctors, and high-risk occupational groups should be properly vaccinated.
