Bovine brucellosis

What is bovine brucellosis?

Bovine brucellosis, or Bang's disease is one of the most common forms of brucellosis. The disease is caused by brucella - slow-moving, the ubiquitous bacteria. The source of infection - pets. The incubation period can last from two weeks to several months. At the onset of the disease symptoms can be different - from obshey weakness to severe headaches, diarrhea, fever, and chills. Then there is the characteristic fluctuation of body temperature in an infected person. At regular intervals, it goes up to 41°C, and then returning to normal. In medicine, a temperature variation is called undulating fever. Danish scientist, physician and veterinarian Bernhard Bang (1848-1932) was the first who studied and described an infectious disease.. Today the disease is often called brucellosis.

Symptoms of bovine brucellosis

  • Severe headaches.
  • Fluctuations in body temperature.
  • Diarrhea.
  • Chill.
  • Fever.

Causes of bovine brucellosis

This infectious disease is caused by the bacterium Brucella. People get bovine brucellosis from sick animals in the vast majority of cases. The bacteria are transmitted through contact with contaminated milk, meat, urine, feces, amniotic fluid of animals. Cases of transmission from person to person recorded only rarely.

Treatment of bovine brucellosis

Antibiotics impact on agents of brucellosis, as in all bacteria. Antibiotics are prescribed in combination with sulfonamides. After recovery, the person should be observed for several months. With timely treatment prognosis is favorable. Brucellosis can be vaccinated, but it is effective only for a few weeks.

Bovine brucellosis

If detected a case of brucellosis, workers livestock farms and slaughterhouses, farmers must take appropriate preventive measures. Sick animals pass to slaughter infected dairy and meat products consumed or destroyed after heat treatment. The causative organism is also found in secretions of infected animals, so in order to avoid its spread disinfect pens. Purebred animals are isolated and make them vaccinated. People also need vaccinations.

With suspected brucellosis should seek emergency medical attention.

To confirm the diagnosis, the doctor makes a laboratory analysis of blood or urine. If this is indeed brucellosis, the physician should report the disease to the appropriate public health authorities.

Course of the disease

First, the patient experiences a general malaise, loss of appetite and sleep disturbance. Then the temperature is increased, headache, pain in joints and muscles appear. Cervical and axillary lymph nodes increases. The liver and spleen are also increasing. At this time, fluctuations in body temperature observed. With proper treatment sequelae after recovery the patient can be identified. With delayed treatment the disease can get chronic and last for a very long time (about 2-3). In this case, Brucella affects the internal organs: heart, lungs, liver and brain. Damage to the nervous system leads to mental disorder. Sometimes a person who has had the disease Bang, there is increased irritability, sensitivity, sweating.

Brucella have high activity in the environment. In water, they can survive 5 minutes in the soil - 3 minutes, frozen meat - more than five months, in cow's milk - about 45 days.

Undulant fever

Brucella can cause not only bovine brucellosis, but also a so-called undulant fever. In the past, the disease was very common in the Mediterranean countries. The source of infection - pets (goats, sheep). Infection usually occurs through the alimentary.
