Microbiology (3.3) Virology + Lab TechniquesDiverse Structure and Function of Viruses - classified by genetic homology Viral Infection and Diseases - virulence = ability of virus to induce disease in infected host - Avirulent strains replicate with no pathological or symptomatic consequence - no significant correlation b/t structure of viruses + diseases they induce! - DNA/RNA - Enveloped/Naked - Large/Small Genomes Brainpower Read More Overview viral infections (pic) Viral Hepatitis is Induced by Diverse Viruses Classification of Viruses Differential Diagnosis and Treatment - Proper differential diagnosis and treatment considers both molecular + medical virology based information. - How is virus transmitted, natural reservoir? - What disease is associated with each virus, common symptoms, risk factors? - What is distinctive about the virus that allows it to cause disease? - How is the virus identified clinically, how is diagnosis confirmed? - How is infection treated and prevented? Factors that Contribute to Infection Contributions to Viral Disease and Interventions What is a Virus? - viruses are NOT alive! +sense = you can translate a protein from it -sense = must make a + strand to translate Virus Structure - are very large macromolecular assemblies - too small to be seen by light microscopy - Many viral structures have been determined by electron microscopy (EM) - Single images of particles, acquire 1000's + analyze digitally
