QUESTION: Which of the following disease is not caused by bacteria?

A  Cholera

B   Typhoid

C  Tuberculosis

D  Malaria

ANSWER:    Malaria


Aspect Bacterial Diseases Protozoan Diseases
Causative agent ·        Caused by bacteria (single-celled microorganisms). ·        Caused by protozoa (single-celled eukaryotic organisms).
Cell Structure ·        Have distinct cell walls and cellular structures. ·        Lack cell walls and have more complex cellular structures.
Cell Type ·        Bacteria are prokaryotic cells without a nucleus. ·        Protozoa are eukaryotic cells with a distinct nucleus.
Shape and size ·        cocci

·        bacilli

·        Spiral

·        Typically smaller, with some exceptions.

·        Amoeboid

·        Flagellated

·        Ciliated

·        Generally larger and more complex.

Transmission ·        Through air

·        Through infected water

·        Through direct contact

·        Through contaminated water and food Through vectors e.g., mosquitoes

·        Through direct contact

Examples of Diseases ·        Tuberculosis

·        Cholera

·        Streptococcal infections

·        Typhoid

·        Malaria

·        Amoebic dysentery

·        Giardiasis

·        Sleeping sickness also known as African trypanosomiasis

Mode of Reproduction ·        Through binary fission ·        Through binary fission

·        Through budding etc.

Treatment ·        Many bacterial diseases are treatable with antibiotics. ·        Treated using antiprotozoal drugs.
Host Range ·        Bacterial diseases can infect humans, animals, and plants. ·        Protozoan diseases often have specific hosts, including humans and animals.
Immune Response ·        Bacterial infections usually elicit an immune response. ·        Protozoan infections may trigger immune responses, but some protozoa can evade immune detection.
Disease Mechanisms ·        Bacteria cause diseases through production of toxins and invasion of host tissues etc. ·        Protozoa cause diseases by damaging host tissues, interfering with normal functions.
Prevention ·        Prevention involves hygiene, sanitation, vaccination and antibiotics. ·        Prevention includes water and food safety, vector control and public health measures.
