Diagnostic Considerations

The signs and symptoms of brucellosis can be nonspecific and can mimic those of many other diseases; therefore, meticulous attention is needed in making the diagnosis and in treating patients. The primary diagnostic pitfall is failure to consider possible Brucella infection in a patient with history that suggests a possible source of infection (eg, a farmer, a traveler to an endemic region, or a veterinarian).

In addition to the conditions listed in the differential diagnosis, other problems to be considered include the following:

  • Collagen-vascular disease
  • Erythema nodosum
  • Fever of unknown origin
  • Malignancy (eg, lymphoma)
  • Rickettsial diseases
  • Sacroiliitis
  • Vasculitis
