Bone marrow aspirate and venous blood  was  collected  aseptically  from  the  cases  were  processed  simultaneously.  The  results  of these two cultures were compared. 

Results:  Total 60 cases  of Kala-azar were included in the study of which 32 were male  and 28 were  female.   Amastigote  form  of  Leishmania  donovani  were  detected  in  56  (93.33%)  samples with  high  titre  of  parasitemiae  and  119  (18%)  in  the  blood  sample  with  low  parasitemiae. Sensitivity and Specificity of the test was calculated of the bone marrow sample test have more sensitivity (98%) and specificity (100%) over the sensitivity (90%) and specificity (96%) of blood smear test.
