Comparison of blood, bone marrow aspirate, stool and urine cultures in the diagnosis of enteric fever.

A total of 288 specimens made up of 84 specimens each of blood, stool, urine and 36 specimens of bone marrow aspirates were collected from enteric fever patients. The blood specimen was used for cultural diagnosis and malaria parasite (MP) test, while serum from the blood was screened by Widal test. The remaining specimens (bone marrow aspirate, stool and urine) were only used for cultural diagnosis, but their cultural diagnostic sensitivity were only calculated from the patients whose Widal tests were positive.
