Brucellosis of cow type


What is cow-type brucellosis?

Brucellosis cow type, or Bang's disease - one of the most common forms of brucellosis . It is caused by brucella - a sedentary, ubiquitous bacteria. The source of the infection is domestic animals. The incubation period can last from two weeks to several months. At the onset of the disease, the symptoms can be different - from general weakness to severe headaches, diarrhea, fever and chills. Then a characteristic fluctuation of body temperature is noted. At certain intervals, it rises to 41 ° C, then normalizes. In medicine, such a temperature fluctuation is called an undulating fever. For the first time this infectious disease was studied and described by a Danish scientist, physician and veterinarian Bernhardt Bang (1848-1932 gg.). Today, the disease is often called brucellosis.

Causes of cow-type brucellosis

This infectious disease is caused by brucella bacteria. In the vast majority of cases, people become infected from sick animals. Bacteria are transmitted through contact with infected milk, meat, urine, feces, amniotic fluid of animals. Cases of transmission of infection from person to person are recorded very rarely.

Treatment of cow-type brucellosis

The pathogens of brucellosis , like all bacteria, are treated with antibiotics, which are prescribed in combination with sulfonamides. After recovery, a person is monitored for several months. With timely treatment, the prognosis is favorable. Brucellosis can be vaccinated, but it is effective only for several weeks.

If a case of brucellosis is detected, workers of livestock farms, meat processing plants and farmers should take appropriate preventive measures. Sick animals are given for slaughter, infected dairy and meat products are destroyed or consumed only after heat treatment. The causative agent of the disease is also found in the secretions of sick animals, therefore, to avoid its spreading, the paddocks are disinfected. Pedigree animals are isolated and vaccinated. People are also shown vaccination.

If you suspect a brucellosis, you should immediately call your doctor.

To confirm the diagnosis, a laboratory analysis of blood or urine is done. If this is really brucellosis, then the doctor should report the disease to the relevant health authorities.

Cervical and axillary lymph nodes, liver, spleen are enlarged. There is a fluctuation in body temperature. With proper treatment after recovery of residual phenomena in the patient is not noted. With untimely treatment, the disease can take a chronic form and last very long (about 2-3). In this case brucella affect the internal organs: heart, lungs, liver and brain. The defeat of the nervous system leads to frustration of the psyche. Sometimes a person who has undergone Bang's disease shows increased irritability, sensitivity, and sweating.

Brucella highly active in the external environment. In water, the viability is 5 minutes, in the soil - 3 minutes, in frozen meat - more than 5 months, in cow's milk - about 45 days.
