Background
- Causes brucellosis, also called Malta fever
Microbiology
- Facultative intracellular, Gram-negative coccobacillus
- Catalase-positive, oxidase positive, nitrate positive, and urease positive
- Risk group 3 organism
- When suspected, plates should be sealed and it should not be set up for mass spectrometry
Epidemiology
- Zoonotic transmission transmitted by ingesting contaminated food (such as unpasteurized milk products), direct contact with an infected animal, or inhalation of aerosols
Clinical Manifestations
- Exposure to unpasteurized milk products or animals
- Undulating fever
- Headache, arthralgia, night sweats, fatigue, anorexia
- Arthritis, spondylitis, osteomyelitis
- Orchitis and epididymitis
- Foul-smelling sweat
