Brucellosis

Brucellosis is an infectious disease caused by various bacteria in the Brucella family. It is considered public health risk, as it can be transmitted to humans. In animals, this disease is characterized by miscarriage and reduced reproduction.

Brucellosis can also infect other animal species such as camels, buffalo, yaks, rodents and reindeer, as well as humans.

Contamination

TRANSMISSION OF BRUCELLOSIS

Direct contact

Transmission occurs through direct contact with infected animals, including contact with excretions, skin wounds, ocular conjunctiva and nasal mucosa.

Oral transmission

Transmission can also occur through ingestion of unpasteurized milk or dairy products.

SIGNS AND SYMPTOMS OF BRUCELLOSIS

Human

Acute febrile illness (undulating fever or Malta fever), which can become chronic and lead to serious complications affecting the muscles, cardiovascular system and central nervous system.

Animal

Miscarriages or lack of reproduction

ECONOMIC LOSSES

CONSEQUENCES ON HEALTH AND FOOD SECURITY 

Slaughtered animals

Movement restrictions and closure of national and international markets

Work-related disease for farmers and veterinarians without correct protection

Consumers falling ill due to unpasteurized products

HOW TO CONTROL AND PREVENT BRUCELLOSIS

Prevention: The best solution

Adequate biosafety and health measures
Helps reduce the spread of brucellosis to healthy animals.

Testing
Performing diagnostic tests periodically to determine status of the disease in order to establish eradication programs.

Vaccination
Vaccination is the most effective measure to prevent brucellosis and, therefore, the associated economic and healthcare losses.
