Give a brief description of protozoa, fungi, and helminths
What will be an ideal response?
Answer: Protozoa are single-celled, nucleus-containing microorganisms. Protozoa are much larger than bacteria and have complex internal structures. Types of protozoa include amoeboids, flagellates, ciliates, and sporozoans. Fungi can be single-celled or multi-celled organisms. They have a reproductive structure bearing spores, which are known allergens. Fungal infections are known as mycoses. Many mycoses are opportunistic infections. Helminths are parasitic worms and are complex, multicellular organisms. They often have well-developed reproductive systems capable of producing large numbers of offspring. Infections with helminths are often called infestations.
