Questions: Microbiology involves the study of microscopic organisms or agents, including which of the following: Bacteria Viruses Protozoa Fungi Helminths

The correct answers are:

• Bacteria
• Viruses
• Protozoa
• Fungi
• Helminths

Explanation for each option:

1. Bacteria: Correct. Microbiology involves the study of bacteria, which are microscopic, single-celled organisms.

2. Viruses: Correct. Viruses are also studied in microbiology, as they are microscopic agents that can infect living organisms.

3. Protozoa: Correct. Protozoa are single-celled eukaryotic organisms that are studied in microbiology.

4. Fleas: Incorrect. Fleas are not microscopic; they are visible to the naked eye and are typically studied in entomology, not microbiology.

5. Fungi: Correct. Fungi, including yeasts and molds, are studied in microbiology, especially those that are microscopic.

6. Helminths: Correct. Although helminths (parasitic worms) are often macroscopic, their eggs and larvae are microscopic, and they are studied in microbiology, particularly in the context of parasitology.

In summary, microbiology encompasses the study of bacteria, viruses, protozoa, fungi, and helminths, but not fleas.
