Eukaryotic organisms contain a nucleus surrounded by a membrane. Sleeping sickness and malaria are caused by protozoans which are eukaryotic organisms. Sleeping sickness is caused by Trypanosoma, while malaria is caused by Plasmodium. Typhoid and cholera on the other hand, are caused by bacteria. They are prokaryotic in nature i.e., they do not contain a membrane bound nucleus.
