    Study Notes

    Microbiology: Viruses, Fungi, Protists, and Prions

    • Bacteriophages have lytic or lysogenic life cycles, transferring genetic material to bacteria.
    • Viruses are not cells, but small infectious particles consisting of nucleic acid enclosed in a protein coat.
    • Viruses are obligate intracellular parasites and have a limited host range for infection.
    • COVID-19, caused by SARS-CoV-2, is a coronavirus that primarily causes mild infections but can lead to severe disease in some individuals.
    • Vaccines, biotherapeutics, and test and trace strategies are potential solutions for controlling the COVID-19 pandemic.
    • Fungi are eukaryotes with diverse characteristics, including chitin cell walls and mycelia networks for absorption.
    • Fungal diseases include systemic, subcutaneous, cutaneous, and superficial mycoses, caused by various fungi species.
    • Fungi can produce toxic metabolic products and mycotoxins, leading to pathogenic properties like hallucinations and carcinogenic effects.
    • Algae, which contain chlorophyll and carry out oxygenic photosynthesis, exhibit diversity in forms and pigments.
    • Protozoa are unicellular organisms without cell walls, including amoebae, ciliates, flagellates, and sporozoans.
    • Prions are infectious proteins causing brain diseases in mammals, and they are resistant to UV irradiation and devoid of DNA or RNA.
    • Prion diseases include scrapie in sheep, mad cow disease, and Creutzfeldt-Jakob disease in humans.
