Diagnosis of brucellosis meningitis

Clinical symptoms of brucellosis are extremely variable. Most commonly, onset occurs 1-2 months after exposure. In the acute form, brucellosis takes the form of a flulike illness, with fever, sweats, malaise, anorexia, headache, myalgia, and back pain.

In the undulant form (< 1 year from onset of illness), symptoms include undulant fevers, arthritis, and orchiepididymitis in males. Neurological sequelae occur in as many as 5% of patients. In the chronic form (>1 year from onset), a chronic fatigue syndrome–like picture with depression and arthritis is typical.

Other complications of brucellosis include granulomatous hepatitis, spondylitis, anemia, leukopenia, thrombocytopenia, uveitis, optic neuritis, papilledema, and endocarditis. Diagnosis is confirmed by the isolation of bacteria from the Brucellaceae family from a bacterial culture or an increase over time in antibodies in the blood that are specific for Brucella species.
