Question

Black water fever and enlarged spleen is caused by

• A. Tryanosoma cruzi
• B. Salmonella typhi
• C. Leismania donovani
• D. Plasmodium falciparum

Answer 1

The correct option is D Plasmodium falciparum

Blackwater fever is a complication of malaria in which red blood cells burst in the bloodstream (haemolysis), releasing haemoglobin directly into the blood vessels and into the urine, frequently leading to kidney failure. Spleen becomes enlarged during malaria because of filtering out of excessive destroyed RBC after the haemolysis and occurs not only during malaria, during many infectious/non infectious diseases following with the RBC haemolysis.

Thus, the correct answer is option D.
