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

Management
