Study Notes
Viral Pathogenesis and Pandemics, Fungal and Protist Infections, and Prions
- Viruses can penetrate and grow inside host cells, inhibit host DNA/RNA and protein synthesis, and cause a Cytopathic effect (CPE).
- COVID-19, caused by a Coronavirus (SARS-CoV-2), is highly problematic due to its large number of asymptomatic carriers, effective human-to-human spread, and severe disease in some individuals.
- Vaccines and biotherapeutics show promise in combating COVID-19, with many drugs and monoclonal antibodies in the pipeline.
- Faster and cheaper tests are being developed for pandemic control through test and trace strategies.
- Fungi are eukaryotes with chitin cell walls and diverse species, including molds and mushrooms, and can cause mycoses with varied pathogenic properties.
- Fungal diseases, such as systemic mycoses and superficial mycoses, are caused by toxic metabolic products and parasitic properties of fungi.
- Ergot toxin from Claviceps purpurea and Aflatoxin from Aspergillus are examples of pathogenic properties of fungi.
- Fungi can be filamentous (molds) or macroscopic (mushrooms) and unicellular (yeasts), with different modes of reproduction and pathogenic potential.
- Algae, containing chlorophyll and carrying out oxygenic photosynthesis, are a large and diverse group, including pathogenic species like red tide dinoflagellates and Pfeisteria.
- Lichens are a symbiotic relationship between fungi and algae, while protozoa are unicellular organisms without cell walls, with various groups like amoebae, ciliates, flagellates, and sporozoans, some of which are pathogenic.
- Prions are infectious proteins that cause brain diseases in mammals, propagate by converting normal proteins into the prion version, and are associated with diseases like scrapie in sheep, mad cow disease, and Creutzfeldt-Jakob disease in humans.
- Prions are distinct from conventional viruses, devoid of DNA or RNA, and composed primarily of a protein called Prion.
