Three Arab children with neonatal brucellosis are described. The first presented with late neonatal hyperbilirubinaemia, the second with a septicoemia-like picture and the third was born prematurely and presented with respiratory distress. The diagnosis of brucellosis was based on a positive blood culture and on a high or rising titre of antibodies to the Brucella organism. All the three neonates responded well to antibiotic therapy as monitored by a Brucella titre of less than 1:40 and a negative blood culture 10 weeks after the onset of therapy. The three mothers had Brucella infections during pregnancy and the Brucella agglutination titre of the breast milk was high. No Brucella microorganism was isolated from the breast milk. The mode of transmission of brucellosis in neonates is discussed.
