    Study Notes

    Microbiology Overview

    • Bacteriophages have lytic or lysogenic life cycles and can infect bacteria like Escherichia coli
    • Viruses are not cells, but small infectious particles consisting of nucleic acid enclosed in a protein coat, and replicate only in host cells
    • COVID-19, a coronavirus, predominantly causes mild infections but can lead to severe disease in some individuals
    • Vaccines and biotherapeutics show promise in combating COVID-19, but there are concerns about the duration of protection
    • Fungi are eukaryotes with diverse species, causing systemic, subcutaneous, cutaneous, and superficial mycoses
    • Fungal diseases can result from toxic metabolic products, allergic responses, and pathogenic properties like toxin production
    • Algae, containing chlorophyll, can be microscopic or macroscopic, with some species being pathogenic, causing red tide and fish deaths
    • Lichens are a symbiotic relationship between fungus and algae, where the fungus provides an anchor and the algae provide photosynthesis
    • Protozoa, unicellular organisms without cell walls, include amoebae, ciliates, flagellates, and sporozoans, some of which are pathogenic
    • Prions are infectious proteins causing brain diseases in mammals, propagating by converting normal proteins into the prion version
    • Prion diseases include scrapie in sheep, mad cow disease, and Creutzfeldt-Jakob disease in humans
    • Prions are distinct from conventional viruses, devoid of DNA or RNA, and are primarily composed of a protein called Prion
