Which of the following diseases is not caused by bacteria ?

The correct answer is Amoebiasis.

Key Points

• Amoebiasis is a parasitic infection caused by the protozoan Entamoeba histolytica, not bacteria.
• This disease is transmitted via contaminated food and water and primarily affects the intestines.
• Symptoms include diarrhea, abdominal pain, and dysentery, making it distinct from bacterial infections.
• Unlike bacterial diseases such as Typhoid, Cholera, and Diphtheria, Amoebiasis is classified as a protozoal disease.
• Effective treatment involves anti-parasitic medications like metronidazole or tinidazole, which target protozoa rather than bacteria.

Additional Information

• Typhoid: A bacterial infection caused by Salmonella typhi, spread through contaminated food and water.
• Cholera: A bacterial disease caused by Vibrio cholerae, leading to severe diarrhea and dehydration.
• Diphtheria: Caused by Corynebacterium diphtheriae, it affects the throat and respiratory system and can be life-threatening.
• Bacteria vs Protozoa: Bacteria are single-celled prokaryotic organisms, while protozoa are single-celled eukaryotic organisms, often causing diseases like Amoebiasis and Malaria.
• Prevention of Amoebiasis: Ensure proper sanitation, drink clean water, and maintain good hygiene to avoid protozoal infections.
