The haematological profile in 20 culture proven patients with typhoid fever of varying age and of both sexes was studied. Significant changes observed were anaemia, leucopenia, eosinopenia, thrombocytopenia and sub-clinical disseminated intravascular coagulation. The bone marrow of typhoid patients showed myeloid maturation arrest, decrease in the number of erythroblasts and megakaryocytes with increased phagocytic activity of histiocytes.
