Brucella

Brucella
The number one cause of bacterial zoonotic infections worldwide.
  • Brucella bacteria are associated with livestock; epidemics among farm animals lead to economic devastation.
Brucella melitensis, Brucella abortus and Brucella suis
Brucella melitensis is associated with most human infections.
  • Intracellular pathogens that cause chronic infections with granuloma formation, particularly in the reticuloendothelial system.
  • Treatment includes doxycline and streptomycin or rifampin; relapse is common.
  • Brucellosis mimics other infectious diseases; because of this, diagnosis is often delayed.
Brucellosis
  • Early infection is characterized by undulant fever with chills, sweating, coughing, vomiting, and weakness.
  • Advanced infection is systemic with multi-organ effects and increased risk of abortion.
