brucellosis
MONDO:0005683
Brucellosis is a bacterial infection that spreads from animals to people via unpasteurized dairy products or by exposure to contaminated animal products or infected animals. Animals that are most commonly infected include sheep, cattle, goats, pigs, and dogs. Brucellosis can cause of range of signs and symptoms, some of which may persist or recur. Initial symptoms may include fever, sweats, malaise, anorexia, headache, fatigue, and/or pain in the muscles, joints, and/or back. Symptoms that may persist or recur include fevers, arthritis, swelling of the testicle and scrotum, swelling of the heart (endocarditis), neurologic symptoms (in up to 5% of cases), chronic fatigue, depression, and/or swelling of the liver or spleen. People who are in jobs or settings that increase exposure to the bacteria are at increased risk for infection. Antibiotics are used to treat brucellosis. Recovery may take a few weeks to several months, and relapses are common. Death from brucellosis is rare, occurring in no more than 2% of cases.

Brucellosis
Brucellosis is a zoonotic disease spread primarily via ingestion of unpasteurized milk from infected animals. It is also known as undulant fever, Malta fever, and Mediterranean fever. The causative agents, Brucella, are small, Gram-negative, nonmotile, nonspore-forming, rod-shaped (coccobacilli) bacteria. They function as facultative intracellular parasites, and can cause lifelong chronic disease. Four species infect humans: B. abortus, B. canis, B. melitensis, and B. suis. B. abortus is less virulent than B. melitensis and is primarily a disease of cattle. B. canis affects dogs. B. melitensis is the most virulent and invasive species; it usually infects goats and occasionally sheep. B. suis is of intermediate virulence and chiefly infects pigs. Symptoms include profuse sweating and joint and muscle pain. Brucellosis has been recognized in animals and humans since the early 20th century.
