Brucellosis in man--II. Isolation of the causative organisms with special reference to blood picture and urine constituents.
Blood and urine samples were collected from 50 patients with febrile splenomegaly suspected to be Malta fever in Sharkia fever hospitals, Egypt. Blood samples were subjected to isolation of Brucellae; blood counts and erythrocyte sedimentation rate. Urine analysis. Four strains of brucella were isolated. Two of these isolated first from the 50 patients and typed as Br. melitensis Biotype I and the others were recovered secondly and thirdly from serologically positive patients and typed as Br. abortus Biotype I. All the strains from positive serology, titre ranging from 1/160-1/640. Br. melitensis is more readily isolated from the blood than Br. abortus. Blood picture of serologically positive Malta fever showed three patients with mild leukopenia; two with relative lymphocytosis; two with secondary anaemia and three with accelerated erythrocyte sedimentation rate. Urine analysis revealed five patients with albuminuria.
